Hello,
When I have:
CONFIG_MIPS_DB1550
CONFIG_SOC_AU1550
CONFIG_SOC_AU1X00
CONFIG_PM
MEM_SDREFCFG is used at:
arch/mips/au1000/common/power.c::pm_do_freq()
While the MEM_SDREFCFG constant is declare only for CONFIG_SOC_AU1000,
CONFIG_SOC_AU1500, CONFIG_SOC_AU1100 at:
include/asm-mips/mach-au1x00/au1000.h
Maybe MEM_SDREFCFG should be defined for CONFIG_SOC_AU1X00?
Or there should be #ifdef for its usage in power.c?
Best Regards,
Alon Bar-Lev.

Hello,
Forgot to write that I checked mips & linus gits, and the problem still exists.
Best Regards,
Alon Bar-Lev.

PM code is generally broken and unmaintained, so no wonder. I don't
remember if anyone has fixed CPU context restoration code (it uses a "skewed"
stack frame).

I've just looked into the Au1550 datasheet and indeed it doesn't have such
register; its SDDRAM controller is not compatible with older SoCs.

Looks like you'll have to invent something... ;-)

So I guess it's time to mark the whole PM stuff as BROKEN?

So suspend modes on these boards are not supported?
Only "Always On" configuration is supported?
Or there is another method to preserve power?

Sleep mode is supported according to the code. But as I've said PM bits
haven't been maintained -- probably since the submission.

Thanks!
Will it be maintained? Are there any plans?
Is there, a missing features list (TODO)?
Or this is completely unsupported board?

Alon Bar-Lev.
