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.

c39f44dc6f powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from board
Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards
pretty much do the same thing.  The only variations are in how many
controllers or DIMMs per controller exist.  To make this work we
standardize on the names of the SPD_EEPROM_ADDRESS defines based on the
use case of the board.

We allow boards to override get_spd to either do board specific fixups
to the SPD data or deal with any unique behavior of how the SPD eeproms
are wired up.

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

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.

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.

PLATFORM_CPPFLAGS += -DCONFIG_MPC8548=1

However these are all captured in the config.h and thus redudant.

cb151aa2cf pci/fsl_pci_init: Fold fsl_pci_setup_inbound_windows into fsl_pci_init
Every platform that calls fsl_pci_init calls fsl_pci_setup_inbound_windows
before it calls fsl_pci_init.  There isn't any reason to just call it
from fsl_pci_init and simplify things a bit.

048e7efe91 85xx/86xx: Replace in8/out8 with in_8/out_8 on FSL boards
The pixis code used in8/out8 all over the place.  Replace it with
in_8/out_8 macros.

6bb5b41229 85xx: Report which "bank" of NOR flash we are booting from on FSL boards
The p2020DS, MPC8536DS, MPC8572DS, MPC8544DS boards are capable of
swizzling the upper address bits of the NOR flash we boot out of which
creates the concept of "virtual" banks.  This is useful in that we can
flash a test of image of u-boot and reset to one of the virtual banks
while still maintaining a working image in "bank 0".

The PIXIS FPGA exposes registers on LBC which we can use to determine
which "bank" we are booting out of (as well as setting which bank to
boot out of).
