2015-10-24arm: Switch aarch64 to using generic global_data setupSimon Glass
There is quite a bit of assembler code that can be removed if we use the generic global_data setup. Less arch-specific code makes it easier to add new features and maintain the start-up code. Drop the unneeded code and adjust the hooks in board_f.c to cope. Tested on LS2085ARDB and LS2085AQDS (armv8 SoC).

2015-09-12arm: Correct comments in crt0.S for the recent SPL improvementsSimon Glass
The current comments need a bit of tweaking since we now support stack and global_data relocation in SPL. Also add a reference to the README. For AArch64 this is not implemented, so leave a TODO for this. Signed-off-by: Simon Glass <sjg@chromium.org> Reported-by: Tim Harvey <tharvey@gateworks.com>
2015-07-27arm64: Handle arbitrary CONFIG_SYS_MALLOC_F_LEN valuesThierry Reding
The encoding of the sub instruction used to handle CONFIG_SYS_MALLOC_F_LEN can only accept certain values, and the set of acceptable values differs between the AArch32 and AArch64 instructions sets. The default value of CONFIG_SYS_MALLOC_F_LEN works with either ISA. Tegra uses a non-default value that can only be encoded in the AArch32 ISA. Fix the AArch64 crt0 assembly so it can handle completely arbitrary values.

2015-04-23armv8/ls2085aqds: NAND boot supportScott Wood
This adds NAND boot support for LS2085AQDS, using SPL framework. Details of forming NAND image can be found in README. Signed-off-by: Scott Wood <scottwood@freescale.com> [York Sun: Remove +S from defconfig after commit 252ed872] Signed-off-by: York Sun <yorksun@freescale.com>
