This patch series add full relocation and cache support for arm based boards. I did this for arm1136, arm_cortexa8 and arm926ejs based boards. As this change is not compatible to old code, before this can go to mainline *all* plattforms and boards have to be converted! As I don;t have access to all plattforms/ boards I need help here! Also I couldn;t test all boards, so please test and report, send bugfixes!
Relocation support: changed arch/arm/lib/board.c to get in sync with arch/powerpc/lib/board.c maybe it is possible to merge 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. As I don;t know all architectures/boards, I set this value where I didn;t find such a stack, for example in the processor, to RAM, as RAM is actual setup in low_level_init.S. Please check this for boards where this is in RAM to find a "better" place. 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 support for arm_cortexa8 and arm1136. As this is a RFC, this patch series is in a state where things *can* and *should* be discussed! Also I think, it would be good to create an "arm-relocation.git" where patches (for example board maintainers bugfixes) for this change are collected. I tested the patch series on the qong(arm1136), beagle(arm_cortexa8) tx25(arm926ejs) and magnesium(arm926ejs) boards. Relocation worked fine.
