Hi Stefan,
In the system, only below regions were mapped and only these regions can be erased/programmed.
0x54: 0x000f0000 FREG0: Flash Descriptor region (0x00000000-0x0000ffff) is read-write. 0x58: 0x07ff0200 FREG1: BIOS region (0x00200000-0x007fffff) is read-write.
The other regions were not used on this platform.
Creating a romlayout file and programming only the specified regions solves the issue. The patch works fine.
Hello Rajasekhar,
great to hear that it works for you. Your patch as sent previously does have a few issues (flash chip patch included, redundancies that might be worthwhile to refactor) that need to be resolved before integrating it. I would probably want to take it and merge it manually when integrating chromiumos' baytrail patch. To be able to do this we need your confirmation by signing off the patch as explained here: http://www.coreboot.org/Development_Guidelines#Sign-off_Procedure
