arm, at91: corvus board updates
- corvus board fix problems with toshiba nand chips
on the corvus board problems with toshiba chips
Manufacturer ID: 0x98 Chip ID: 0xdc encounterd.
Solve this in the following way:
- set other nand timings
- enable CONFIG_SYS_NAND_READY_PIN
- correct the MACH_TYPE setting
