25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
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.

59e0d611ad da850evm: fix linux bootparam address
This patch fixes the LINUX_BOOT_PARAM_ADDR define to be based off of
PHYS_SDRAM_1 instead of CONFIG_SYS_MEMTEST_START. On da830 they are the same
thing but on da850 the CONFIG_SYS_MEMSTART define is offset from the
PHYS_SDRAM_1 start.

Without this patch it is not possible to boot linux on da850 -- bootm hangs
at "Uncompressing Linux... done, booting the kernel."

3d248d37e1 da850evm: basic MII EMAC support
The current da850evm support in u-boot/master omits any use of
the davinci EMAC. This patch adds basic support for the EMAC using
the MII PHY found on the baseboard of the EVM. The MAC address is
read from the environment variable 'ethadd'. Note that this is
different from the da850evm support in the u-boot omapl1 tree
where the MAC address is read from SPI flash.

6b2c646895 da850evm: setup NAND support under CONFIG_USE_NAND
The current da850evm config is missing the pieces for NAND support that can be
found in Sandeep's u-boot-davinci tree [1].

This patch adds NAND support in the spirit of the support in the u-boot-davinci
tree where NAND support for the da850evm can be enabled by putting a single
'#define CONFIG_USE_NAND' at the top of the include/configs/da850evm.h file.

11080ab66d ARM: relocation: don't undef CONFIG_SYS_ARM_WITHOUT_RELOC
There were some #undef's of CONFIG_SYS_ARM_WITHOUT_RELOC added to a few board
configs as part of the arm relocation series; but these are not needed now as we
do not #undef what is not #defined in the first place.

9700375624 da8xx: fixup ARM relocation support
Split the existing dram_init for da8xx when ARM reloc is enabled, like the
changes to arch/arm/cpu/arm926ejs/orion5x/dram.c in
0f234d263b17ccf1b8fd776eb8c15b7cdb27a887 by Heiko Schocher <hs@denx.de>.

Without these changes gd->ram_size is '0' which leads to incorrect relocation
when CONFIG_SYS_ARM_WITHOUT_RELOC is defined and the board does not boot.

We use get_ram_size to dynamically calculate the available RAM because it runs
on different board version with different ram, as suggested by Heiko in private
communication.

Tested on a da850evm with 128M of DDR2 installed; with both
CONFIG_SYS_ARM_WITHOUT_RELOC defined and undefined.

ab86f72c35 ARM: implement relocation for ARM926
Change the implementation for arm926 to relocate the code to
an arbitrary address in RAM.

Adapt the TX25 (i.MX25), magnesium board to test the changes.

On the tx25 board TEXT_BASE is set to the final relocation
address to prevent one more copying of u-boot code
when relocating. More info see:
