cc15df57b1 powerpc/85xx: verify the localbus device tree address before booting the OS
The localbus controller node in the device tree is typically a root node,
even though the controller is part of CCSR.  If we were to put the lbc
node under the SOC node, then the 'ranges' property in the lbc node would
translate through the 'ranges' property of the parent SOC node, and we
don't want that.

Since the lbc is a separate node, it's possible for the 'reg' property to
be wrong.  This happened with the original version of p1022ds.dts, which
used a 32-bit value in the 'reg' address, instead of a 36-bit address.

2f3a71f235 mpc8xxx: update module_type values from JEDEC DDR3 SPD Specification
Newer JEDEC DDR3 SPD Specifications define several additional values for
the DDR3 module_type field which were undefined when this code was

f2717b47ea powerpc/85xx: clean up and document the QE/FMAN microcode macros
Several macros are used to identify and locate the microcode binary image
that U-boot needs to upload to the QE or Fman.  Both the QE and the Fman
use the QE Firmware binary format to package their respective microcode data,
which is why the same macros are used for both.  A given SOC will only have
a QE or an Fman, so this is safe.

Unfortunately, the current macro definition and usage has inconsistencies.
For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman
firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address
of NAND.  There's no way to know by looking at a variable how it's supposed
to be used.

In the future, the code which uploads QE firmware and Fman firmware will
be merged.

fbc20aab11 powerpc/85xx: always implement the work-around for Erratum SATA_A001
On the P1022/P1013, the work-around for erratum SATA_A001 was implemented
only if U-Boot initializes SATA, but SATA is not initialized by default.  So
move the work-around to the CPU initialization function, so that it's always
executed on the SOCs that need it.

4108508a96 powerpc/85xx: Add workaround for erratum A-003474
Erratum A-003474: Internal DDR calibration circuit is not supported

Impact:
Experience shows no significant benefit to device operation with
auto-calibration enabled versus it disabled. To ensure consistent timing
results, Freescale recommends this feature be disabled in future customer
products. There should be no impact to parts that are already operating
in the field.

Workaround:
Prior to setting DDR_SDRAM_CFG[MEM_EN]=1, do the following:
1. Write a value of 0x0000_0015 to the register at offset
	CCSRBAR + DDR OFFSET + 0xf30
2. Write a value of 0x2400_0000 to the register at offset
	CCSRBAR + DDR OFFSET + 0xf54

33c875366e powerpc/85xx: fixup flexcan device tree clock-frequency
Make the fixup matchable with dts and kernel.  Update the compatible from
"fsl,flexcan-v1.0" to "fsl,p1010-flexcan" and Change the "clock-freq"
property to "clock-frequency".  We also change flexcan frequency from
CCB-clock to CCB-clock/2 according to P1010 spec.

We now keep the old interfaces to make previous kernel work. They should
be removed in the future.

43f082bb7f powerpc/85xx: Add workaround for erratum CPU-A003999
Erratum A-003999: Running Floating Point instructions requires special
initialization.

Impact:
Floating point arithmetic operations may result in an incorrect value.

Workaround:
Perform a read modify write to set bit 7 to a 1 in SPR 977 before
executing any floating point arithmetic operation. This bit can be set
when setting MSR[FP], and can be cleared when clearing MSR[FP].
Alternatively, the bit can be set once at boot time, and never cleared.
There will be no performance degradation due to setting this bit.

d3983ee853 font: split font data from video_font.h
While video_font.h is useful even without referencing the font data, it
is not possible to be included multiple times because it defines font
data array right in the header.

This patch splits the font data array into video_font_data.h and so now
video_font.h can be included multiple times.  This at least solves the
code duplication in board/mcc200/lcd.c.

cca4e4aec1 Reduce build times
U-Boot Makefiles contain a number of tests for compiler features etc.
which so far are executed again and again.  On some architectures
(especially ARM) this results in a large number of calls to gcc.

This patch makes sure to run such tests only once, thus largely
reducing the number of "execve" system calls.

Example: number of "execve" system calls for building the "P2020DS"
(Power Architecture) and "qong" (ARM) boards, measured as:
	-> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board>
	-> grep execve /tmp/foo | wc -l

	Before: After:	Reduction:
==================================
P2020DS 20555	15205	-26%
qong	31692	14490	-54%

As a result, built times are significantly reduced, typically by
30...50%.

a2c1229c39 powerpc/85xx: use fdt_create_phandle() to create the Fman firmware phandles
Function fdt_create_phandle() conveniently creates new phandle properties
using both "linux,phandle" and "phandle", so it should be used by all code
that wants to create a phandle.

The Fman firmware code, which embeds an Fman firmware into the device tree,
was creating the phandle properties manually.  Instead, change it to use
fdt_create_phandle().

* As there are only 4 physical cores sdest can only be 0 to 3
* We assign dqrr & frame data LIODNs for all portals so if they
  are utilized the proper mapping tables can be setup uniquely
  (PAMU stashing)
* We set Portal 6-10 to LIODN offsets 1-5 as the global LIODN
  assignments are tuned around an assumption of at most 5
  partitions.

1605cc9e1b powerpc/mpc86xx: Disable translation for BAT setup
We really shouldn't be overwriting bat registers with translation enabled,
especially when we're executing code using one of them for translating
the current instruction stream.  Instead, disable address translation
while doing the final BAT setup.

In order to do this, setup_bats has to move back to asm code, because we
require translation to be enabled to have a stack for C code.  The yucky
thing about that is that the assembler doesn't like ULL so we have to
switch to using HIGH/LOW pairs for physical addresses that are > 32 bits
in length.

6f5e1dc531 powerpc/8xxx: Add support for interactive DDR programming interface
Interactive DDR debugging provides a user interface to view and modify SPD,
DIMM parameters, board options and DDR controller registers before DDR is
initialized. With this feature, developers can fine-tune DDR for board
bringup and other debugging without frequently having to reprogram the flash.

To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header
file and set an environment variable to activate it. Syntax:

setenv ddr_interactive on

After reset, U-boot prompts before initializing DDR controllers
FSL DDR>

The available commands are
print      print SPD and intermediate computed data
reset      reboot machine
recompute  reload SPD and options to default and recompute regs
edit       modify spd, parameter, or option
compute    recompute registers from current next_step to end
next_step  shows current next_step
help       this message
go         program the memory controller and continue with u-boot

The first command should be "compute", which reads data from DIMM SPDs and
board options, performs the calculation then stops before setting DDR
controller. A user can use "print" and "edit" commands to view and modify
anything. "Go" picks up from current step with any modification and
compltes the calculation then enables the DDR controller to continue u-boot.
"Recompute" does it over from fresh reading.

Unified DDR driver is maintained for better performance, robustness and bug
fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of
overall improvement. It requires changes for board files to customize

To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx
in the header file. No more boards will be accepted without such definition.

Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1

The Frame Manager (FMan) on QorIQ SoCs with DPAA (datapath acceleration
architecture) is the ethernet contoller block.  Normally it is utilized
via Queue Manager (Qman) and Buffer Manager (Bman).  However for boot
usage the FMan supports a mode similar to QE or CPM ethernet collers
called Independent mode.

Additionally the FMan block supports multiple 1g and 10g interfaces as a
single entity in the system rather than each controller being managed
uniquely.  This means we have to initialize all of Fman regardless of
the number of interfaces we utilize.

Different SoCs support different combinations of the number of FMan as
well as the number of 1g & 10g interfaces support per Fman.

We add support for the following SoCs:
 * P1023 - 1 Fman, 2x1g
 * P4080 - 2 Fman, each Fman has 4x1g and 1x10g
 * P204x/P3041/P5020 - 1 Fman, 5x1g, 1x10g

6ca88b0958 powerpc/85xx: relocate CCSR before creating the initial RAM area
Before main memory (DDR) is initialized, the on-chip L1 cache is used as a
memory area for the stack and the global data (gd_t) structure.  This is
called the initial RAM area, or initram.  The L1 cache is locked and the TLBs
point to a non-existent address (so that there's no chance it will overlap
main memory or any device).  The L1 cache is also configured not to write
out to memory or the L2 cache, so everything stays in the L1 cache.

One of the things we might do while running out of initram is relocate CCSR.
On reset, CCSR is typically located at some high 32-bit address, like
0xfe000000, and this may not be the best place for CCSR.  For example, on
36-bit systems, CCSR is relocated to 0xffe000000, near the top of 36-bit
memory space.

On some future Freescale SOCs, the L1 cache will be forced to write to the
backing store, so we can no longer have the TLBs point to non-existent address.
Instead, we will point the TLBs to an unused area in CCSR.  In order for this
technique to work, CCSR needs to be relocated before the initram memory is
enabled.

Unlike the original CCSR relocation code in cpu_init_early_f(), the TLBs
we create now for relocating CCSR are deleted after the relocation is finished.
cpu_init_early_f() will still need to create a TLB for CCSR (at the new
location) for normal U-Boot purposes.  This is done to keep the impact to
existing U-Boot code minimal and to better isolate the CCSR relocation code.

3b4a226305 video: Add SHARP LQ084S3LG01 LCD support on P1022DS
The SHARP LQ084S3LG01 is a TFT LCD used on the P1022DS (revision "C") board.
This device only supports 800x600 resolution, so if that resolution is selected,
assume that this is the device.  The device is attached to the LVDS port
on the P1022DS board.

The existing 800x600 entry (for the PDM360NG board) is actually 800x480,
so we fix that.  To support two different 800x resolutions, the Y-resolution
is now passed to fsl_diu_init() and both values are used to pick the proper
fb_videomode structure.

The data for the 800x600 video mode is originally from Jiang Yutang.

We used <usb.h> for USB_MAX_DEVICE.  However this requires we actual
build in support for USB into u-boot (which should not be required for
device tree fixup).

At this time no FSL SoC that utilizies this code (83xx/85xx) has more
than 2 USB controllers.  So we replace USB_MAX_DEVICE with a local
define FSL_MAX_NUM_USB_CTRLS.

If/when a device shows up with more than 2 controllers we can easily
bump this value or refactor into a proper define per SoC.

Introduce ft_verify_fdt(), a function that is called after the device tree
has been fixed up, that displays warning messages if there is a mismatch
between the physical addresses of some devices that U-Boot has configured
with what the device tree says the addresses are.

This is a particular problem when booting a 36-bit device tree from a
32-bit U-Boot (or vice versa), because the physical address of CCSR is
wrong in the device tree.  When the operating system boots, no messages are
displayed, so the user generally has no idea what's wrong.

26002826c7 powerpc/85xx: remove SERDES4 soft-reset work-around
Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a
bank soft-reset after the bank was configured and enabled, even though
enabling a bank causes it to reset.  Because the reset was required for
multiple errata, it was not properly enclosed in an #ifdef, and so was
not removed with all the other rev1 errata work-arounds.

Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if
bank 2 is enabled, but this was not being done for SERDES protocols 0xF
and 0x10.  The bank reset also happened to enable bank 3 (apparently an
undocumented feature).  Simply removing the reset breaks these two
protocols.

It turns out that every time we call enable_bank(), we do want at least
one lane of the bank enabled, either because the bank is supposed to be
enabled, or because we need the clock from that bank enabled.

For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we
call enable_bank(), because that array is used elsewhere to determine if
the bank is available.

Note that the side effect of these changes is that the work-arounds for
these two errata are now linked.  Specifically, if SERDES-A001 is
enabled, then we need SERDES-8 enabled as well.

Because this was the only SERDES bank soft-reset, there is no need to
implement a work-around for erratum SERDES-A003.

Also fix an off-by-one error in a printf().

APM errata CHIP_21 for the 405EX/EXr (from the rev 1.09 document dated
4/27/11) states that rev D processors may wake up with the wrong feature
set.  This patch implements the APM-proposed workaround.

To enable this patch for your board, add the appropriate define for your
CPU to your board header file.  See kilauea.h for more information.  The
following variants are supported:

#define CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_SECURITY

Please note that if you select the wrong define, your board will not
boot, and JTAG will be required to recover.

Tested on custom boards using:

d90fdba6ca powerpc/85xx: Implement work-around for P4080 erratum SERDES-A001
Bank powerdown through RCW[SRDS_LPD_Bn] for XAUI on FM2 and SGMII on FM1
are swapped.

Erratum SERDES-A001 says that if bank two is kept disabled and after bank
three is enabled, then the PLL for bank three won't lock properly.  The
work-around is to enable and then disable bank two after bank three is
enabled.

ba8e76bd49 powerpc: use 'video-mode' environment variable to configure DIU
Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration.  Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.

The old definition of the "monitor" environment variable only determines
which video port to use for output.  This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port.  The
resolution was hard-coded into board-specific code.  The Linux command-line
arguments needed to be hard-coded to the proper video definition string.

865ff85640 fsl: Change fsl_phy_enet_if to phy_interface_t
The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum.
This meant that drivers which used fsl_phy_enet_if to deal with
PHY interfaces would have to convert between the two (or we would have
to have them mirror each other, and deal with the ensuing maintenance
headache). Instead, we switch all clients of fsl_phy_enet_if over to
phy_interface_t, which should become the standard, anyway.

e820a131f4 fsl_ddr: Don't use full 64-bit divides on 32-bit PowerPC
The current FreeScale MPC-8xxx DDR SPD interpreter is using full 64-bit
integer divide operations to convert between nanoseconds and DDR clock
cycles given arbitrary DDR clock frequencies.

Since all of the inputs to this are 32-bit (nanoseconds, clock cycles,
and DDR frequencies), we can easily restructure the computation to use
the "do_div()" function to perform 64-bit/32-bit divide operations.

On 64-bit this change is basically a no-op, because do_div is
implemented as a literal 64-bit divide operation and the instruction
scheduling works out almost the same.

On 32-bit PowerPC a fully accurate 64/64 divide (__udivdi3 in libgcc) is
over 1.1kB of code and thousands of heavily dependent cycles to compute,
all of which is linked from libgcc.  Another 1.2kB of code comes in for
the function __umoddi3.

It should be noted that nothing else in U-Boot or the Linux kernel seems
to require a full 64-bit divide on my 32-bit PowerPC.

Build-and-boot-tested on the HWW-1U-1A board using DDR2 SPD detection.

b5c8753fa1 powerpc/85xx: Fixup determining PME, FMan freq
On CoreNet based SoCs (P2040, P3041, P4080, P5020) we have some
additional rules to determining the various frequencies that PME & FMan
IP blocks run at.

We need to take into account:
* Reduced number of Core Complex PLL clusters
* HWA_ASYNC_DIV (allows for /2 or /4 options)

On P2040/P3041/P5020 we only have 2 Core Complex PLLs and in such SoCs
the PME & FMan blocks utilize the second Core Complex PLL.  On SoCs
like p4080 with 4 Core Complex PLLs we utilize the third Core Complex
PLL for PME & FMan blocks.

On P2040/P3041/P5020 we have the added feature that we can divide the
PLL down further by either /2 or /4 based on HWA_ASYNC_DIV.  On P4080
this options doesn't exist, however HWA_ASYNC_DIV field in RCW should be
set to 0 and this gets a backward compatiable /2 behavior.

dd50af2515 powerpc/8xxx: Add hwconfig APIs to address early parsing used by DDR init
There are several users of the hwconfig APIs (8xxx DDR) before we have
the environment properly setup.  This causes issues because of the
numerous ways the environment might be accessed because of the
non-volatile memory it might be stored in.  Additionally the access
might be so early that memory isn't even properly setup for us.

Towards resolving these issues we provide versions of all the hwconfig
APIs that can be passed in a buffer to parse and leave it to the caller
to determine how to allocate and populate the buffer.

We use the _f naming convention for these new APIs even though they are
perfectly useable after relocation and the environment being ready.

We also now warn if the non-f APIs are called before the environment is
ready to allow users to address the issues.

Finally, we convert the 8xxx DDR code to utilize the new APIs to
hopefully address the issue once and for all.  We have the 8xxx DDR code
create a buffer on the stack and populate it via getenv_f().

a09b9b68d4 powerpc/8xxx: Refactor SRIO initialization into common code
Moved the SRIO init out of corenet_ds and into common code for
8xxx/QorIQ processors that have SRIO.  We mimic what we do with PCIe
controllers for SRIO.

We utilize the fact that SRIO is over serdes to determine if its
configured or not and thus can setup the LAWs needed for it dynamically.

We additionally update the device tree (to remove the SRIO nodes) if the
board doesn't have SRIO enabled.

Introduced the following standard defines for board config.h:

CONFIG_SYS_SRIO - Chip has SRIO or not
CONFIG_SRIO1 - Board has SRIO 1 port available
CONFIG_SRIO2 - Board has SRIO 2 port available

(where 'n' is the port #)
CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot
CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup)
CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup)

[ These mimic what we have for PCI and PCIe controllers ]

7ea3871e06 MPC8xxx DDR: align informational prints
Add spaces to cause the informational prints to line up with
the ones from init_func_ram() in board.c.  Output now looks like
this:

....
DRAM:  Detected 4096 MB of memory
       This U-Boot only supports < 4G of DDR
       You could rebuild it with CONFIG_PHYS_64BIT
       DDR: 2 GiB (DDR2, 64-bit, CL=5, ECC off)
....

line up and changed to start with "LBC SDRAM" instead of the
confusing "SDRAM".

38dba0c2ff mpc85xx boards: initdram() cleanup/bugfix
Correct initdram to use phys_size_t to represent the size of
dram; instead of changing this all over the place, and correcting
all the other random errors I've noticed, create a
common initdram that is used by all non-corenet 85xx parts.  Most
of the initdram() functions were identical, with 2 common differences:

1) DDR tlbs for the fixed_sdram case were set up in initdram() on
some boards, and were part of the tlb_table on others.  I have
changed them all over to the initdram() method - we shouldn't
be accessing dram before this point so they don't need to be
done sooner, and this seems cleaner.

2) Parts that require the DDR11 erratum workaround had different
implementations - I have adopted the version from the Freescale
errata document.  It also looks like some of the versions were
buggy, and, depending on timing, could have resulted in the
DDR controller being disabled.  This seems bad.

The xpedite boards had a common/fsl_8xxx_ddr.c; with this
change only the 517 board uses this so I have moved the ddr code
into that board's directory in xpedite517x.c

This will initially only be used by TQM85xx, but could be

the name of this define is not 85xx-specific.  WIMGE is a
fairly universal concept, so any ppc platforms that require

c08e5cf7c7 POWERPC: enable --gc-sections and -ffunction-sections -fdata-sections
The switch from archive libraries to partial linking has introduced a
number of problems, that are non-trivial to solve.  For example, it is
no longer possible to include individual object files in the linker
script as we did before for example in the case of boards with
embedded environment to fill up the gap caused by the need to align
the environment on flash erase block boundaries.

The best (but unfortunately not easiest) approach to address this
problem is to enable -ffunction-sections (and -fdata-sections) so
we can again (and even in much finer granularity) place certain code
where we want it.  When doing this step, it seems only consequent to
also add --gc-sections which has the added benefit of reducing the
memory footprint of the U-Boot image (both in flash and in RAM).

Unfortunately, this requires changes to a lot of linker scripts.

fa11dbe56d arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings work
As we try to get rid of board specific config.mk files we must
provide a way for board specific settings of the LDSCRIPT variable
(path to the linker script) where needed.

We now implement the following hierarchy:

- Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board
  config file.
- If CONFIG_SYS_LDCONFIG is not set, and the system is booting from
  NAND (CONFIG_NAND_SPL is set), then a board specific linker
  script board/$(BOARDDIR)/u-boot-nand.lds gets used.
- If we are not booting from NAND, we test if a processor specific
  linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we
  use that.
- As default, arch/powerpc/config.mk gets used.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

553f09823c Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZE
CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be
some end address; to make the meaning more clear we rename it into
CONFIG_SYS_INIT_RAM_SIZE

No other code changes are performed in this patch, only minor editing
of white space (due to the changed length) and the comments was done,
where noticed.

Note that the code for the PATI and cmi_mpc5xx board configurations
looks seriously broken.  Last known maintainers on Cc:

9d64c6bb4a 85xx: Add support for not releasing secondary cores via 'mp_holdoff'
Some OSes require that secondary cores not be initialized when they
are booted (eg VxWorks).  By default when U-Boot is compiled with the
CONFIG_MP option all secondary cores are brought out of reset and held
in spinloops.  Setting the "mp_holdoff" environment variable to 'yes'
or '1' will cause U-Boot to leave secondary cores in their default
state.

The memory test is performed after DDR initialization when U-boot stills runs
in flash and cache. On recent mpc85xx platforms, the total memory can be more
than 2GB. To cover whole memory, it needs be mapped 2GB at a time using a
sliding TLB window. After the testing, DDR is remapped with up to 2GB memory
from the lowest address as normal.

If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for
further debugging.

e95a0611f2 powerpc/85xx: fix rev.2 job queue LIODN error storm
pumping line-rate traffic though a p4080 rev.2, which
is configured to encrypt packets prior to forwarding through
an IPsec tunnel, gets this error:

of_platform ffe302000.jq: DECO: desc idx 22: LIODN error. DECO was trying
to share from itself or from another DECO but the two Non-SEQ LIODN
values didn't match or the "shared from" DECO's Descriptor required that
the SEQ LIODNs be the same and they aren't.

Since high traffic rates cause DECOs to begin to start sharing
shared descriptors amongst themselves, and DECOs inherit job queue
LIODNs when accessing shared descriptors, and a recently discovered
rev.2 h/w erratum requires all sharing job queues in a partition
have same liodn assignment, reassign the first job queue's liodn
assignment to the rest.

e02d449644 ppc4xx: Cleanup of PVR detection code in cpu.c
This patch cleans the PVR detection code in check_cpu() up a bit.
Basically the strings are better seperated, resulting in an easier
to understand and maintain code version.

The #ifdef's couldn't be removed easily because of two reasons:

- Some SoC revisions have the same PVR, so need a way to differentiate
  between those two SoC's.
- In some case statements registers only available in this SoC variant
  are referenced.

Instead I moved the CONFIG_440 #ifdef a bit, so that 405 platforms don't
add this 440 detection code and vice versa. Resulting in this U-Boot
image size change:

405EX (Kilauea):     408 bytes less
440EPx (Sequoia):    604 bytes less
460EX (Canyonlands): 564 bytes less

afabb498b7 ppc4xx: Big header cleanup part 2, mostly PPC405 related
This cleanup is done by creating header files for all SoC versions and
moving the SoC specific defines into these special headers. This way the
common header ppc405.h and ppc440.h can be cleaned up finally.

As a part from this cleanup, the GPIO definitions for PPC405EP are
corrected. The high and low parts of the registers (for example
CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in
the wrong order. This patch now fixes this issue by switching these
xxxH and xxxL values. This brings the GPIO 405EP port in sync with all

This patch changes the behaviour of the fdt_fixup_nor_flash_node()
function. Now it doesn't patch the size of the "reg" property with the
chip-select size, but with the size returned from the new function
flash_get_bank_size(). This function will return per weak default the
flash size of the bank (bank = chip-select numer) detected by the flash
driver. If this does not fit your needs, this function may be overridden
by a board specific one.

For this the parameters needed to be changed. So I intentionally squashed
the PPC4xx stuff using this routine into this patch. Otherwise it would
not be git-bisectable anymore.

The board specific function for the AMCC/APM Ebony eval board is now
included in this patch version.

cdb749778a Rename getenv_r() into getenv_f()
While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function.  This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
vs. getgrent_r, etc.).

Unfortunately this was a misleading name, as in U-Boot the "_r"
generally means "running from RAM", i. e. _after_ relocation.

To avoid confusion, rename into getenv_f() [as "running from flash"]

58eb869ffc ppc4xx: Add "ecctest" command to test/simulate ECC errors
This patch adds the "ecctest" command to test and simulate ECC errors
(single bit and/or double bit) while running from SDRAM. Currently only
the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT).

This is done by copying and calling functions, modifying the SDRAM
controller operation mode, in internal SRAM/OCM.

For correctable ECC errors (single bit) only the status will be printed
since the DDR2 controller doesn't provide the faulting address:

=> ecctest 1000000 1
Using address 01000000 for 1 bit ECC error injection
ECC: Correctable error

Uncorrectable ECC errors (double bit) will also display the faulting
address:

=> ecctest 1000000 2
Using address 01000000 for 2 bit ECC error injection
ECC: Uncorrectable error at 0x0001000000

To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST
in the board config header.

Tested on katmai and t3corp.

adopt a common name for the immap layouts that include the lbc - this was
previously known as either im_lbc or lbus; use the former.

In addition, create accessors for the BR/OR regs that use in/out_be32
and use those instead of the mismash of access methods currently in play.

54841ab50c Make sure that argv[] argument pointers are not modified.
The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands.  Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".

This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:

int main (int argc, char **argv)
{
	while (--argc > 0 && **++argv == '-') {
/* ====> */	while (*++*argv) {
			switch (**argv) {
			case 'd':
				debug++;
				break;
			...
			default:
				usage ();
			}
		}
	}
	...
}

The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell.  With the modification, the compiler will prevent this with
an
	error: increment of read-only location '*argv'

N.B.: The code above can be trivially rewritten like this:

	while (--argc > 0 && **++argv == '-') {
		char *arg = *argv;
		while (*++arg) {
			switch (*arg) {
			...

4978e60584 ppc4xx: Cleanup Boot/FLASH TLB reassignment for PPC440/460
Background Info:
Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via
init.S) to speed up the boot process. In relocate_code (start.S) the
cache inhibit attribute for this TLB is set to disable cache. This is
needed for the CFI FLASH driver.

This patch now cleans this code up:
- CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not
  defined in the top of this file. This way, we can remove an ugly
  #ifdef in this code.
- Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..."
  statement with "#if defined(CONFIG_440)".
- Remove unnecessary cache invalidate calls resulting in faster bootup.

066003b2c5 ppc4xx: Enable overwriting of default scan window for IBM DDR2 controller
This patch makes it possible to overwrite the default auto-calibration
scan window (SDRAM_WRDTR.[WDTR], SDRAM_CLKTR.[CKTR] values) with
board specific values. The parameters of the weak default function are
corrected as well. This way we don't need the casts any more.

This feature will be used by an upcoming PPC460GT board port.

By not defining CONFIG_SYS_PCI_MASTER_INIT and CONFIG_SYS_PCI_TARGET_INIT,
PCI support (host and adapter) will not be enabled. But it's still
possible to use the U-Boot PCI infrastructure for the PCIe ports.

This configuration option is needed for a new 460GT board, which uses

This commit implements a workaround at least for the most blatant
problem: using memcpy() from NOR flash. We rename the assembler
routine into __memcpy() and provide a wrapper, which will use a
byte-wise copy loop for unaligned source or target addresses when
reading from NOR flash, and branch to the optimized __memcpy()
in all other cases, thus minimizing the performance impact.

Tested on lite5200b and TQM5200S.

This code also supports two different bootcount versions:

a) Use 2 separate words (2 * 32bit) to store the bootcounter
b) Use only 1 word (2 * 16bit) to store the bootcounter

Version b) was already used by MPC5xxx.
