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()
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).
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?
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.
Or there should be #ifdef for its usage in power.c?
Looks like you'll have to invent something... ;-)
