[U-Boot] [PATCH 04/11] arm: cm4008, cm41xx: use common cfi_flash support
Yann Vernier
yann.vernier at orsoc.se
Thu Aug 9 15:33:08 CEST 2012
This change allows use of other flash chips than the two supported by
the cm4008 flash.c. Tested with Micrel KSZ8695X demo board.
---
Changes for v2:
- Update cm41xx also
- Remove unused board specific flash code
Changes for v3:
- Do not define to 1 where it is not required, just define
Changes for v4:
- Define flash bank characteristics (for big constant cleanup)
- Poll status for AMD flash (as on KS8695X demo board)
