[U-Boot] [Patch 2/2] MIPS: do not modify variable before relocate_code

Because timestamp is declared as `static', we needn't initialize it by writing it a zero. If we do it before relocate_code, we will write into a flash address(0xbfc0). Signed-off-by: Zhi-zhou Zhang --- arch/mips/cpu/mips32/time.c |1 - arch/mips/cpu/mips64/time.c |

[U-Boot] [Patch 1/2] MIPS: fix a latent bug on initialize $gp

If bal is 8 bytes aligned, the _gp will not be 8 bytes aligned. then the following ld insntrustion generates a Adel exception. So here make _gp be always aligned in 8 bytes. Signed-off-by: Zhi-zhou Zhang --- arch/mips/cpu/mips64/start.S |5 - 1 file changed, 4 insertions(+), 1 deletion

As so far, U-Boot has already supports mips32. But there are some differences between mips64 and mips32. Such as different ABI, different output format. so this patch adds mips64 support. I use cross compiler from clfs and build U-Boot like this: export CROSS_COMPILE=/home/zhangzz/work/clfs/sys_ro
