Why can't this work via atags (or DT for that matter)? atags have always said where ram starts and we should be able to write some code that parses the atags/DT and figures out the final resting place of the decompressed image.
Possibly. But that would be an MSM special case.
Hmm. I thought ST-Erricson folks had something similar.
Anyway, maybe we've been going about this the wrong way. Couldn't we just make TEXT_OFFSET be 0x00208000 and then make sure to remove the first 2MB of memory in a machine->reserve() routine if we're MSM?
Something like PHYS_OFFSET=0xN0000000 and TEXT_OFFSET=0x00208000 so that our text ends up at the right place (0xN0208000) and AUTO_ZRELADDR will be happy. This seems to work as long as I fixup the atags to say memory starts at 0xN000000 instead of 0xN0200000.
