2016-01-14arm: move gd handling outside of C codeAlbert ARIBAUD
As of gcc 5.2.1 for Thumb-1, it is not possible any more to assign gd from C code, as gd is mapped to r9, and r9 may now be saved in the prolog sequence, and restored in the epilog sequence, of any C functions. Therefore arch_setup_gd(), which is supposed to set r9, may actually have no effect, causing U-Boot to use a bad address to access GD. Fix this by never calling arch_setup_gd() for ARM, and instead setting r9 in arch/arm/lib/crt0.S, to the value returned by board_init_f_alloc_reserve().

2016-01-14Fix board init code to respect the C runtime environmentAlbert ARIBAUD
board_init_f_mem() alters the C runtime environment's stack it is actually already using. This is not a valid behaviour within a C runtime environment. Split board_init_f_mem into C functions which do not alter their own stack and always behave properly with respect to their C runtime environment.

2016-01-14hash.c: Conditionally compile hash_command, static hash_showTom Rini
The function hash_show is now only called by hash_command, so mark it as static (and drop from hash.h). We only call hash_command when any of CONFIG_CMD_CRC32, CONFIG_CMD_SHA1SUM or CONFIG_CMD_HASH are set. Since hash.c is linked in unconditionally we must take extra care with functions that bring in read-only strings as these will not be discarded. Signed-off-by: Tom Rini <trini@konsulko.com>

2016-01-13image: check "bootm_low" and "bootm_size" if "initrd_high" is missingMasahiro Yamada
To boot Linux, we should prevent Initramdisk and FDT from going too high. Currently, boot_relocate_fdt() checks "fdt_high" environment first, and then falls back to getenv_bootm_mapsize() + getenv_bootm_low() if "fdt_high" is missing. On the other hand, boot_ramdisk_high() only checks "initrd_high" to get the address limit for the Initramdisk. We also want to let this case fall back to getenv_bootm_mapsize() + getenv_bootm_low().
