Rafal mentioned to me off-list that some documentation about this 
suspend/wakeup mechanism would be preferable. Here his notes:

- regarding the U-Boot piece I'd only like to see some explanation (as a 
comment or short readme file) of the overall concept and scenario as it 
is not intuitive at all and rather difficult to understand all the 
ramifications and constraints from looking at the code only

So Domen, could you please either send a reworked patch with this 
documentation (preferable some file in doc/README.xxx) or just send a new 
patch with only this documentation?


BTW: Wolfgang reminded me, that putting this stuff into the u-boot-ppc4xx 
repository is not a good solution. I'll try to move this over to
