When I use ichache_enable or dcache_enable in uboot,it crash

[陈希]

Hi,

	In the very begin of the uboot, the dcache is disable and the icache
is enable. The code runs in flash nomarlly. Then the uboot should jump to
ram and if I don't  disable icache the uboot will crash. I can't enable the
dcache too. The more serious problem is that when I boot the linux kernel
,it will stop at init_mmu. I think it is the same reason. Please help me.

Thanks & Br,
Andy
