powerpc/nand spl: link libgcc
Recent GCC (4.4+) performs out-of-line epilogues in some cases, when
optimizing for size. It causes a link error for _restgpr_30_x (and similar)
if libgcc is not linked.
It actually increases size with very small binaries, due to the fixed size
of the out-of-line code, and not having any functions that actually need to
restore more than 2 or 3 registers. But I don't see a way to turn it off,
other than asking GCC to optimize for speed -- which may also increase
size for some boards.

p1022ds: fix switching of DIU/LBC signals
On the P1022, the pins which drive the video display (DIU) are muxed with the
local bus controller (LBC), so if the DIU is active, the pins need to be
temporarily muxed to LBC whenever accessing NOR flash.
The code which handled this transition is checking and changing the wrong

Also add a follow-up read after a write to NOR flash if we're going to
mux back to DIU after the write, as described in the P1022 RM.

tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode
Removed setting Auto-Neg by default, however this is believed to be
proper default configuration for initialization of the TBI interface.
Instead we explicitly set CONFIG_TSEC_TBICR_SETTINGS for the
XPedite5370 & XPedite5500 boards that use a Broadcomm PHY which require
Auto-Neg to be disabled to function properly.
This addresses a breakage on the P2020 DS & MPC8572 DS boards when used
with an SGMII riser card. We also remove setting
CONFIG_TSEC_TBICR_SETTINGS on the P1_P2_RDB family of boards as now the
default setting is sufficient for them.

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

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

Some systems need to relocate the env_addr pointer early because the
location it points to will get invalidated before env_relocate is
called. One example is on systems that might use a L2 or L3 cache
in SRAM mode and initialize that cache from SRAM mode back to being
a cache in cpu_init_r.
We set this on the 85xx boards that have support for NAND, SPI, or
SDHC/MMC boot support as they use a secondary cache in SRAM mode and
need the env_addr pointer relocated since we change from SRAM to normal
cache mode in cpu_init_r.
Also removed CONFIG_SYS_SPL as its not used anywhere.

cfi_flash: fix bug introduced while recent change to flash_get_size()
commit ec50a8e389863ac35bfd9d9a2e8b30187318e59e
"cfi_flash: handle 'chip size exceeds address window' situation"
added 3rd argument to flash_get_size() but didn't fix all the
function calls from the board specific code. Many boards have
their own flash_get_size() definitions in the board code and
use them there, but some boards (e.g. tqm834x, tqm85xx, pdm360ng)
use flash_get_size() from the cfi_flash.c driver.
The bug shows up if the value of the "max_size" argument (which
is not defined when calling the function with two arguments)
happens to be less than "info->size". In this case on the
affected boards we end up with a bank of reduced size and
in the worst case might even be not able to update U-Boot or
to boot the kernel from flash:
