It can be optimised out by the compiler otherwise resulting
in obscure errors like a board not booting.
This has been documented in README since 2006 when these were
first fixed up for GCC 4.x.

Convert the variable omap3_evm_version to u32 to work around
some broken linkers from older tool chains. E.g. CodeSourcery's
2009q1-203 ld 2.19.51.20090205. Without this, these linkers
stop linking 'omap3_evm' or at least issue a warning. Like
arm-none-linux-gnueabi-ld: section .bss [8003f5e0 -> 8007e337] overlaps section .rel.dyn [8003f5e0 -> 80044e57]
arm-none-linux-gnueabi-ld: section .dynsym [80044e58 -> 80044ef7] overlaps section.bss [8003f5e0 -> 8007e337]
arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5e0 overlaps previous sections

controller to do the validation. This will cause problem when
the host supports Low Voltage Range. Change the validation

After booting the u-boot, and first using some SD card (such as Sandisk 2G SD
card), because the field 'clock' of struct mmc is zero, this will cause
the read transfer is always active and SDHC DATA line is always active,
therefore, driver can't handle the next command.
Therefore, we use mmc_set_clock to setup both the data structure and HW
to the initial clock speed of 400000Hz.

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.

This patch fix a problem for the pcie enumeration for mpc83xx cpus. Without
this we will not get correct value in hose->regions[...].
The pointer *reg in function mpc83xx_pcie_init_bus() shall not be changed.
Because we will use this pointer as a parameter to call function
mpc83xx_pcie_register_hose().

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
bits in PMUXCR.
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.

According to Freescale reference manuals (eg section "13.4.4.2
Programming the UPMs" of the P4080 Reference Manual):
"Since the result of any update to the MxMR/MDR register must be in
effect before the dummy read or write to the UPM region, a write to
MxMR/MDR should be followed immediately by a read of MxMR/MDR."
The UPM on a custom P4080-based board did not work without performing
a read of MxMR/MDR after a write.

The following commit:
commit 46e91674fb4b6d06c6a4984c0b5ac7d9a16923f4

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.
Additionally, we clean up the code a bit to remove an unnecessary second
define.

Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss

The usage of bss values in drivers before initialisation of bss is forbidden.

This change allows the davinci timer functions to be used before
relocation since it avoids using static variables prior to BSS being
made available.
The code is based on that used in the at91 timers, modified to use
a davinci specific hardware timer. It also maintains reset_timer()
to allow deprecated timer usage to continue to work (for example,
in nand_base.c)

All code that attemots to access variables in BSS before relocation
(for example directly or indirectly by board_init_f()) needs to be
fixed. Especially timer.c needs to fix on most of the ARM platforms.
This patch makes timer related variables in gd_t available for
all ARM implementations.

I doubt the stack_setup() was defective before:
we load the current location of _start and compare against destination
of relocate_code(). If we are already there we shoud skip the
relocation and jump over to clear_bss. Before the clear_bss was also skipped.

we need to be aware of that fact.
