Hi!
Some fixes, improvements from last time:
- saving/restoring of some registers inside sleep code
(so bestcomm and pic patches can be dropped, yay)
- improvements in FEC code for deep-sleep
- set up wakeup GPIO so Efika can wake too
- patch against latest u-boot (doh)
Patches are based on
MPC52xx uart power management.
Not sure how exactly this should be written, but this seems
to work, and works around a few seconds delay in resume.

Suspend and resume for FEC on MPC52xx.
Note that resume is a bit different for lite5200b low-power mode.

Implement deep-sleep on MPC52xx.
SDRAM is put into self-refresh with help of SRAM code
(alternatives would be code in FLASH, I-cache).
Interrupt code must also not be in SDRAM, so put it
in I-cache.
MPC52xx core is static, so contents will remain intact even
with clocks turned off.
U-Boot part of Lite5200b low power mode support.
Puts SDRAM out of self-refresh and transfers control to
address saved at physical 0x0.

I don't see any structural problems with this code,

As I understand the decrementer, this is basically the timer tick in the

Can you post the oops that you are seeing, what you need to find out
is what instruction image that is causing the illegal instruction
exception. Once you have that it will be easier to figure out what's
going on.

Can you please try following patch.
ok, I patched the kernel now and was able to read the ic2 chip 100
times successfully. I will run the programm the next 20 hours and give
then a shot feedback.
But the first impression is good.
