arm: add full relocation / cache support

This patch series add full relocation and cache support for arm based boards. I test this for arm1136, arm_cortexa8 and arm926ejs based boards.

Relocation support:

!! This change is not compatible to old code !!

If you want to compile in old style, you can set

CONFIG_SYS_ARM_WITHOUT_RELOC

but this possibility will be removed soon, so please adapt your board(s)

changed arch/arm/lib/board.c to get inline with arch/powerpc/lib/board.c maybe it is possible to snyc them to one arch/generic/lib/board.c?

This approach is similiar to powerpc, so there is a need for an initial stack pointer addr defined through CONFIG_SYS_INIT_SP_ADDR.

Please also read doc/README.arm-relocation There is more info what is done, and maybe should be done.

Cache support:

I used the patches from Alessandro Rubini:
http://lists.denx.de/pipermail/u-boot/2010-January/067099.html

and rebased them to actual code. Also, in case of full relocation, the position of the TLB can not be set on compile time, instead it is calculated in board_init_f() and stored in gd. Also added cache support for arm_cortexa8 and arm1136.

Heiko Schocher (26):
arm: get rid of bi_env
ARM: flush cache for arm926
ARM: cp15: setup mmu and enable dcache
ARM V7 (OMAP): add data cache support, test on Beagle board ARM (ARM11): add data cache support, test on Qong board
relocation: fixup cmdtable
common: move TOTAL_MALLOC_LEN to include/common.h
i2c: fix command usage help
disk/part.c: fix relocation fixup
i2c, omap24xx: set bus_initialized only after relocation. nand_boot_fsl_nfc.c: make "nfc" a "static const" pointer
ARM: add relocation support
ARM: implement relocation for ARM11
ARM: implement relocation for ARM V7 (OMAP)
ARM: implement relocation for ARM926
ARM: implement relocation for ARM920

- changes since previous patch set
- add CONFIG_SYS_ARM_WITHOUT_RELOC
- changed order of patches -> cache patches are independent from relocation patches
- add missing cpu types:

    arm1176  arm720t  arm920t  arm925t  arm946es  arm_intcm
    ixp  lh7a40x  pxa  s3c44b0  sa1100

- only converted boards which I had tested
- rebased againt current top of tree
