0118033b67 powerpc/85xx: implement check for erratum A-004849 work-around
The work-around for erratum A-004849 ("CoreNet fabric (CCF) can exhibit a
deadlock under certain traffic patterns causing the system to hang") is
implemented via the PBI (pre-boot initialization code, typically attached
to the RCW binary).  This is because the work-around is easier to implement
in PBI than in U-Boot itself.

It is still useful, however, for the 'errata' command to tell us whether
the work-around has been applied.  For A-004849, we can do this by verifying
that the values in the specific registers that the work-around says to
update.

1956e431f8 powerpc/85xx/p5040: add CONFIG_SYS_PPC64, del CONFIG_SYS_FSL_ELBC_MULTIBIT_ECC
The P5040 has an e5500 core, so CONFIG_SYS_PPC64 should be defined in
config_mpc85xx.h.  This macro was absent in the initial P5040 patch because
it crossed paths with the patch that introduced the macro.

Also delete CONFIG_SYS_FSL_ELBC_MULTIBIT_ECC, since it's not used in the
upstream U-Boot.  It's a holdover from the SDK.

e76cd5d4cf 8xxx: Change all 8*xx_DDR addresses to 8xxx
There were a number of shared files that were using
CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and
several variants (DDR2, DDR3). A recent patchset added
85xx-specific ones to code which was used by 86xx systems.
After reviewing places where these constants were used, and
noting that the type definitions of the pointers assigned to
point to those addresses were the same, the cleanest approach
to fixing this problem was to unify the namespace for the
85xx, 83xx, and 86xx DDR address definitions.

This patch does:

s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g

All 85xx, 86xx, and 83xx have been built with this change.

c97cd1ba48 spl/85xx: new SPL support
Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL
and CONFIG_SPL_BUILD, respectively.  CONFIG_NAND_SPL can be removed once
the last mpc85xx nand_spl target is gone.

CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't
seem right to overload it for meaning SPL as well as nand_spl does.  Even
if it's somewhat appropriate for the main u-boot, the SPL itself isn't
(necessarily) ramboot, and we don't have separate configs for SPL and
main u-boot.  It was also inconsistent, as other platforms such as
mpc83xx didn't use CONFIG_RAMBOOT in this way.

8bc50f0b6d powerpc/mpc8xxx: move LAW code into arch/powerpc/cpu/mpc8xxx
It's arch code and not a driver, so move it where it belongs.  When it
originally went into drivers/misc there was no 8xxx CPU directory.

This will make new-SPL support a little easier since we can keep the CPU
stuff together and not need to pull stuff in from drivers/misc.

7f0a22ff25 powerpc/mpc85xx: fix TLB alignment
In the RAMBOOT/SPL case we were creating a TLB entry starting at
CONFIG_SYS_MONITOR_BASE, and just hoping that the base was properly
aligned for the TLB entry size.  This turned out to not be the case
with NAND SPL because the main U-Boot starts at an offset into the image
in order to skip the SPL itself.

Fix the TLB entry to always start at a proper alignment.  We still assume that
CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary
thus requiring multiple TLB entries.

c60795f41d usb: use linux/usb/ch9.h instead of usbdescriptors.h
Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.

As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.

Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.

This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

eef1cf2d5c include/linux/byteorder: import latest endian definitions from linux
u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives.  Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h.  They come with 'const' added for some swab functions, so
fix those up, too:

include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]

Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).

We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:

macb.c:54:0: warning: "barrier" redefined [enabled by default]

In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)).  This fixes
arch/powerpc/lib/bootm.c:

bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'

powerpc sparse builds yield:

the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was

19e4a00965 powerpc/boot: Change the compile macro for SRIO & PCIE boot master module
Currently, the SRIO and PCIE boot master module will be compiled into the
u-boot image if the macro "CONFIG_FSL_CORENET" has been defined. And this
macro has been included by all the corenet architecture platform boards.
But in fact, it's uncertain whether all corenet platform boards support
this feature.

So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add
a special macro for every board which can support the feature. This
special macro will be defined in the header file
"arch/powerpc/include/asm/config_mpc85xx.h". It will decide if the SRIO
and PCIE boot master module should be compiled into the board u-boot image.

may make an inaccurate calculation, resulting in a non-optimal tap point.

eb53941206 powerpc/mpc85xx: software workaround for DDR erratum A-004468
Boot space translation utilizes the pre-translation address to select
the DDR controller target. However, the post-translation address will be
presented to the selected DDR controller. It is possible that the pre-
translation address selects one DDR controller but the post-translation
address exists in a different DDR controller when using certain DDR
controller interleaving modes. The device may fail to boot under these
circumstances. Note that a DDR MSE error will not be detected since DDR
controller bounds registers are programmed to be the same when configured
for DDR controller interleaving.

f31cfd1925 powerpc/mpc8xxx: Fix DDR initialization waiting for D_INIT
When ECC is enabled, DDR controller needs to initialize the data and ecc.
The wait time can be calcuated with total memory size, bus width, bus speed
and interleaving mode. If it went wrong, it is bettert to timeout than
waiting for D_INIT to clear, where it probably hangs.

Fix handling quad-rank DIMMs in a system with two DIMM slots and first
slot supports both dual-rank DIMM and quad-rank DIMM.

For systems with quad-rank DIMM and double dual-rank DIMMs, cs_config
registers need to be enabled to maintain proper ODT operation. The
inactive CS should have bnds registers cleared.

Fix the turnaround timing for systems with all chip-selects enabled. This
wasn't an issue before because DDR was running lower than 1600MT/s with
this interleaving mode.

Fix DDR address calculation. It wasn't an issue until we have multiple
controllers with each more than 4GB and interleaving is disabled.

It also fixes the message of DDR: 2 GiB (DDR3, 64-bit, CL=0.5, ECC off)
when debugging DDR and first DDR controller is disabled. With the fix,
the first enabled controller information will be displayed.

The liodn offsets are interleaved to get better cache
utilization. As an example, given 3 pci controllers,
the following liodns are generated for the pci endpoints:

d59c557049 powerpc/srio: Workaround for srio erratrm a004034
Erratum: A-004034
Affects: SRIO

Description: During port initialization, the SRIO port performs
lane synchronization (detecting valid symbols on a lane) and
lane alignment (coordinating multiple lanes to receive valid data
across lanes). Internal errors in lane synchronization and lane
alignment may cause failure to achieve link initialization at
the configured port width.

An SRIO port configured as a 4x port may see one of these scenarios:

1.	One or more lanes fails to achieve lane synchronization.
	Depending on which lanes fail, this may result in downtraining
	from 4x to 1x on lane 0, 4x to 1x on lane R (redundant lane).

2.	The link may fail to achieve lane alignment as a 4x, even
	though all 4 lanes achieve lane synchronization, and downtrain
	to a 1x. An SRIO port configured as a 1x port may fail to complete
	port initialization (PnESCSR[PU] never deasserts) because of
	scenario 1.

Impact: SRIO port may downtrain to 1x, or may fail to complete
link initialization. Once a port completes link initialization
successfully, it will operate normally.

320d53da60 powerpc mpc85xx: Only clear TSR:WIS in watchdog_reset.
We should only write TSR_WIS to the SPRN_TSR register in
reset_85xx_watchdog.

The old code would cause the timer interrupt to be acknowledged when the
watchdog was reset, and we would then get no more timer interrupts.
This bug would affect all mpc85xx boards that have the watchdog enabled.

move most of mpc8xx hooks from cmd_ide.c into ide_preinit() and newly created
ide_init_postreset() (invoked after calling ide_reset after ide_preinit),

confusingly, these hooks are used by more than just mpc8xx-based boards, and
therefore are placed in arch/ppc/lib/

Move the registration of serialN_device ports from default

The newly implemented mpc512x_serial_initialize() function, which is
implemented inside of the mpc512x serial driver allows encapsulation
of serialN_device within the mpc512x serial driver itself.

Also, remove the exports of serialN_device from include/serial.h
as they are no longer needed. This is simply because the implementation of
default_serial_console() is wrapped into the mpx512x serial driver and
the default console is picked by CONFIG_SERIAL<N> macro in config file.

e5ab702a6c powerpc: re-add bi_ip_addr to bd_t struct
Since commit 50a47d0523
(net: punt bd->bi_ip_addr) booting old 2.4.x ppc kernels
is broken due to changed offsets of the fields in struct bd_t.
Offsets of the fields after removed bi_ip_addr are wrong,
causing wrong bus clocks and console baudrate configurations
and various other issues. Re-add the bi_ip_addr field to preserve
backward compatibility with older ppc kernels. Setting bi_ip_addr
in board.c is not really needed, grepping in the 2.4 linux tree
shows that bi_ip_addr is not accessed there. Adding bi_ip_addr
to struct bd_t for other arches isn't needed it seems. bd_t is
not used by other arches in the 2.4 linux tree.

33eee330cc powerpc/fsl-corenet: work around erratum A004510
Erratum A004510 says that under certain load conditions, modified
cache lines can be discarded, causing data corruption.

To work around this, several CCSR and DCSR register updates need to be
made in a careful manner, so that there is no other transaction in
corenet when the update is made.

The update is made from a locked cacheline, with a delay before to flush
any previous activity, and a delay after to flush the CCSR/DCSR update.
We can't use a readback because that would be another corenet
transaction, which is not allowed.

We lock the subsequent cacheline to prevent it from being fetched while
we're executing the previous cacheline.  It is filled with nops so that a
branch doesn't cause us to fetch another cacheline.

Ordinarily we are running in a cache-inhibited mapping at this point, so
we temporarily change that.  We make it guarded so that we should never
see a speculative load, and we never do an explicit load.  Thus, only the
I-cache should ever fill from this mapping, and we flush/unlock it
afterward.  Thus we should avoid problems from any potential cache
aliasing between inhibited and non-inhibited mappings.

NOTE that if PAMU is used with this patch, it will need to use a
dedicated LAW as described in the erratum.  This is the responsibility
of the OS that sets up PAMU.

b5f7c8732a powerpc/corenet_ds: Master module for boot from PCIE
For the powerpc processors with PCIE interface, boot location can be
configured from one PCIE interface by RCW. The processor booting from PCIE
can do without flash for u-boot image. The image can be fetched from another
processor's memory space by PCIE link connected between them.

The processor booting from PCIE is slave, the processor booting from normal
flash memory space is master, and it can help slave to boot from master's
memory space.

When boot from PCIE, slave's core should be in holdoff after powered on for
some specific requirements. Master will release the slave's core at the
right time by PCIE interface.

Environment and requirement:

master:
    1. NOR flash for its own u-boot image, ucode and ENV space.
    2. Slave's u-boot image is in master NOR flash.
    3. Normally boot from local NOR flash.
    4. Configure PCIE system if needed.
slave:
    1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
    2. Boot location should be set to one PCIE interface by RCW.
    3. RCW should configure the SerDes, PCIE interfaces correctly.
	4. Must set all the cores in holdoff by RCW.
	5. Must be powered on before master's boot.

For the master module, need to finish these processes:
    1. Initialize the PCIE port and address space.
    2. Set inbound PCIE windows covered slave's u-boot image stored in
       master's NOR flash.
	3. Set outbound windows in order to configure slave's registers
	   for the core's releasing.
    4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2"
	   or "PCIE3" using the following command:

			setenv bootmaster PCIE1
			saveenv

81fa73bab0 powerpc/corenet_ds: Get rid of the CONFIG_SRIOBOOT_SLAVE_PORTx macro
When compile the slave image for boot from SRIO, no longer need to
specify which SRIO port it will boot from. The code will get this
information from RCW and then finishes corresponding configurations.

This has the following advantages:
	1. No longer need to rebuild an image when change the SRIO port for
	   boot from SRIO, just rewrite the new RCW with selected port,
	   then the code will get the port information by reading new RCW.
	2. It will be easier to support other boot location options, for
	   example, boot from PCIE.

"bootmaster" to "SRIO1" or "SRIO2" using the following command:

		setenv bootmaster SRIO1
		saveenv

The "bootmaster" will enable the function of the SRIO boot master, and
this has the following advantages compared with SRIOBOOT_MASTER build
configuration:
	1. Reduce a build configuration item in boards.cfg file.
	   No longer need to build a special image for master, just use a
	   normal target image and set the "bootmaster" variable.
	2. No longer need to rebuild an image when change the SRIO port for
	   boot from SRIO, just set the corresponding value to "bootmaster"

	   for the core's releasing.
	2. Check the SRIO port status when release slave core, if no errors,

5ffa88eca7 powerpc/corenet_ds: Master module for boot from SRIO
For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.

The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:

master:
	1. NOR flash for its own u-boot image, ucode and ENV space.
	2. Slave's u-boot image in master NOR flash.
	3. Normally boot from local NOR flash.
	4. Configure SRIO switch system if needed.
slave:
	1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
	2. Boot location should be set to SRIO1 or SRIO2 by RCW.
	3. RCW should configure the SerDes, SRIO interfaces correctly.
	4. Slave must be powered on after master's boot.

For the master module, need to finish these processes:
	1. Initialize the SRIO port and address space.
	2. Set inbound SRIO windows covered slave's u-boot image stored in
	   master's NOR flash.
	3. Master's u-boot image should be generated specifically by
	   make xxxx_SRIOBOOT_MASTER_config
	4. Master must boot first, and then slave can be powered on.

The original ld script line arch/powerpc/cpu/mpc85xx/start.o
KEEP(*(.bootpg)) is not entirely correct because the start.o file is already
processed by the linker,therefore the file wildcard in "KEEP(*(.bootpg))" will
not process start.o again for bootpg.

3b2001105f powerpc/bootm: Flush ramdisk and device tree image when booting on MP
We already flush the kernel image after we've loaded it to ensure
visiblity to the other cores.  We need to do the same thing for the
ramdisk and device tree images.  In AMP boot scenarios we might not be
HW cache coherent with the secondary core that we are loading and
setting the ramdisk and device tree up for.  Thus we need to ensure
we've flushed the regions of memory utilized by ramdisk and device tree
so the loadding and any modifications (from decompression or fdt updates)
are made visible to the secondary cores.

01baa05643 powerpc: Minimal private libgcc to build on Debian
Standard Debian powerpc and powerpcspe systems only include hard-float
libgcc in their native compilers, which causes scary build warnings when
building U-Boot.

Debian and other PowerPC-supporting distributions used to provide libgcc
and other libraries in a "nof" (soft-float) form in the "multilib"
packages.  As they were completely unused by the distribution and
therefore tended to be very buggy it was decided to save some time on
the part of the maintainers and build-servers by removing them.

Admittedly, right now the linker warnings do not indicate any problems,
as the included routines do not use any floating point at all.

The concern is that if floating-point code were ever added it might
cause hard-float code to be unexpectedly included in U-Boot without
generating a hard error.  This would cause unexplained crashes or
indeterminate results at runtime.

The easiest way to resolve this is to borrow the routines that U-Boot
needs from the Linux kernel, which has the same issue.

Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3().
They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5,
commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+.

The Makefile framework was copied from the U-Boot ARM port.

9839709ea3 mpc85xx: support for Freescale COM Express P2020
This adds support for the Freescale COM Express P2020 board. This board
is similar to the P1_P2_RDB, but has some extra (as well as missing)
peripherals.

Unlike all other mpc85xx boards, it uses a watchdog timeout to reset.
Using the HRESET_REQ register does not work.

This board has no NOR flash, and can only be booted via SD or SPI. This
procedure is documented in Freescale Document Number AN3659 "Booting
from On-Chip ROM (eSDHC or eSPI)." Some alternative documentation is
provided in Freescale Document Number P2020RM "P2020 QorIQ Integrated
Processor Reference Manual" (section 4.5).

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.

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

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.

- externs should be avoided
  (to be cleaned up later)
- no spaces at the start of a line
  (accepted in multi-line #if's)
- Macros with complex values
  (false reports)
- do not use assignment in if condition
  (accepted in one place, where avoiding it would have required an

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%.
