Unfortunately I don't have time right now to investigate this. Right, the function s3c_pm_run_res() gets the memory start and end address based on flag IORESOURCE_MEM and the strcmp "System RAM". Looks like wrong range is marked as "System RAM" . what I found is, even if I access the address "0xf0001000" just after booting using Trace32 debugger it gives error. thats shows that during bootup itself, wrong range is marked as "System RAM", which causes crash the during suspend. Need to dig more.
