[U-Boot-Users] resume from sleeping for au1x00

Hello,

someone are using u-boot to resume from sleeping with au1x00 MIPS processor?

I'm just looking at linux code into file arch/mips/au1000/common/sleeper.S. The function save_and_sleep() does:

/* Now set up the scratch registers so the boot rom will * return to this point upon wakeup. */ la k0, 1f lui k1, 0xb190 ori k1, 0x18 sw sp, 0(k1) ori k1, 0x1c sw k0, 0(k1)

so I suppose that, at wake up, these «scratch registers» can be used by u-boot to restart at correct location... is that right? :-o

Thanks in advance,

Rodolfo
