For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().
With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway. So don't keep this relict any
longer.

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

* add's the new temporary CONFIG_AT91_LEGACY to all board configs
This will need for backward compatiblity, while change the SoC access
to c structures. If CONFIG_AT91_LEGACY is defined, the deprecated
SoC is used.

For some reason the AT91rm9200 lowlevel init writes to a bunch of
reserved or read-only addresses. All the boards seem to define the
value-to-be-written values as zero ... but they shouldn't actually
be writing *anything* there.
No documented erratum justifies these accesses. It looks like maybe
some pre-release BDI-2000 setup code has been carried along by cargo
cult programming since at least late 2004 (per GIT history).
Here's a patch disabling what seems to be bogosity. Tested on a
csb337; there were no behavioral changes.

This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and
changes the default from 8 to 1 for the legacy and the new MTD
NAND layer. This allows to remove all NAND_MAX_CHIPS definitions
in the board config files because none of the boards use multi
chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440
define
#define NAND_MAX_CHIPS CONFIG_SYS_MAX_NAND_DEVICE
but that's bogus and did not work anyhow.

This fixes a naming bug for at91rm9200 lowlevel init code:
NOR boot flash is on chipselect 0, not chipselect 2. This
makes code use the register name from chip datasheets.

Somewhere during development of U-Boot-1.1.3 CONFIG_BOOTBINFUNC was
renamed into CONFIG_INIT_CRITICAL which was 04 Apr 2005 replaced
with CONFIG_SKIP_LOWLEVEL_INIT and CONFIG_SKIP_RELOCATE_UBOOT.
However CONFIG_SKIP_LOWLEVEL_INIT has oposite meaning to
CONFIG_BOOTBINFUNC, so fix configuration to reflect this fact.
I'm sending this patch 4th (!) time in hope it produces at least some
reaction.
