93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

9d0456822c powerpc/mpc85xx: Check return value of find_tlb_idx
find_tlb_idx() is called in board_early_init_r() on multiple boards.
The return value is not checked before being used to disable a TLB.
In normal case the return value wouldn't be -1. In case of a mis-
configuration during porting to a new board, checking the return value
may be helpful to reveal some user errors.

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.

5d065c3e10 powerpc/85xx: don't display address map size (32-bit vs. 36-bit) during boot
Most 85xx boards can be built as a 32-bit or a 36-bit.  Current code sometimes
displays which of these is actually built, but it's inconsistent.  This is
especially problematic since the "default" build for a given 85xx board can
be either one, so if you don't see a message, you can't always know which
size is being used.  Not only that, but each board includes code that displays
the message, so there is duplication.

The 'bdinfo' command has been updated to display this information, so
we don't need to display it at boot time.  The board-specific code is
deleted.

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

b194577b29 hwconfig: Fix dummy initialization of {board, cpu}_hwconfig
Since board_hwconfig & cpu_hwconfig are defined as weak and dont have a
default value they will get put into the BSS if they aren't defined
elsewhere.  This is problematic as we try to utilize hwconfig before
we've relocated and thus BSS isn't setup.

Instead of giving dummy values in the board files that utilize this
feature, we can just initialize the variables to an empty string and
thus move them out of the BSS if they aren't defined elsewhere.

Also made board_hwconfig & cpu_hwconfig arrays to reduce size associated
with string pointers vs arrays.

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.

5a46960883 p2020ds: add alternate boot bank support using the ngPIXIS FPGA
The Freescale P2020DS board uses a new type of PIXIS FPGA, called the ngPIXIS.
The ngPIXIS has one distinct new feature: the values of the on-board switches
can be selectively overridden with shadow registers.  This feature is used to
boot from a different NOR flash bank, instead of having a register dedicated
for this purpose.  Because the ngPIXIS is so different from the previous PIXIS,
a new file is introduced: ngpixis.c.

Also update the P2020DS checkboard() function to use the new macros defined
in the header file.

2feb4af001 fsl: improve the PIXIS code and fix a few bugs
Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx
boards.  This makes the code easier to read and more flexible.

Delete pixis.h, because none of the exported functions were actually being
used by any other file.  Make all of the functions in pixis.c 'static'.
Remove "#include pixis.h" from every file that has it.

Remove some unnecessary #includes.

Make 'pixis_base' into a macro, so that we don't need to define it in every
function.

Add "while(1);" loops at the end of functions that reset the board, so that
execution doesn't continue while the reset is in progress.

Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where
appropriate.

Replace ulong/uint with their spelled-out equivalents.  Remove unnecessary
typecasts, changing the types of some variables if necessary.

Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make
it easier for specific boards to support variations in the PIXIS registers
sets.  No current boards appears to need this feature.

Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD.
Apparently, "pixis_reset altbank" has never worked on this board.

abc76eb6a6 ppc/85xx: Map boot page guarded for MP boot
We already map the page cache-inhibited.  There is no reason we
shouldn't also be marking it guarded to prevent speculative accesses.

5fb6ea3ad3 ppc/85xx: Make flash TLB entry determined at runtime on FSL boards
Rather than hard coding which TLB entry the FLASH is mapped with we can
use find_tlb_idx to determine the entry.

9263e829f0 ppc/85xx: Move to using fsl_setup_hose on P2020 DS
We can use fsl_setup_hose to determine if we are a agent/end-point or
a host.  Rather than using some SoC specific register we can just look
at the PCI cfg space of the host controller to determine this.

01471d538f Revert "ppc/85xx/pci: fsl_pci_init: pcie agent mode support"
This reverts commit 70ed869ea5.

There isn't any need to modify the API for fsl_pci_init_port to pass the
status of host/agent(end-point) status.  We can determine that
internally to fsl_pci_init_port.  Revert the patch that makes the API
change.

70ed869ea5 ppc/85xx/pci: fsl_pci_init: pcie agent mode support
Originally written by Jason Jin and Mingkai Hu for mpc8536.

When QorIQ based board is configured as a PCIe agent, then unlock/enable
inbound PCI configuration cycles and init a 4K inbound memory window;
so that a PCIe host can access the PCIe agents SDRAM at address 0x0

* Supported in fsl_pci_init_port() after adding pcie_ep as a param
* Revamped copyright in drivers/pci/fsl_pci_init.c
* Mods in 85xx based board specific pci init after this change

002741ae86 ppc/85xx: Clean up use of LAWAR defines
On 85xx platforms we shouldn't be using any LAWAR_* defines
but using the LAW_* ones provided by fsl-law.h.  Rename any such
uses and limit the LAWAR_ to the 83xx platform as the only user so
we will get compile errors in the future.

6c97a20d0b ppc/85xx: Introduce RESET_VECTOR_ADDRESS to handle non-standard link address
Some board ports place TEXT_BASE at a location that would cause the
RESET_VECTOR_ADDRESS not to be at 0xfffffffc when we link.  By default
we assume RESET_VECTOR_ADDRESS will be 0xfffffffc if the board doesn't
explicitly set it.

3e7b6c1f2d ppc/8xxx: Refactor code to determine if PCI is enabled & agent/host
Refactor the code into a simple bitmask lookup table that determines if
a given PCI controller is enabled and if its in host/root-complex or
agent/end-point mode.

Each processor in the PQ3/MPC86xx family specified different encodings
for the cfg_host_agt[] and cfg_IO_ports[] boot strapping signals.
