[U-Boot-Users] [PATCH] TQM85xx: add support for Spansion 'N' type flashes.

From: Thomas Waehner thomas.waehner@tqs.de
The 'N' typ flashes have bigger sectors, than the formerly used 'M' types, so the flash layout has to be changed -> new start address of the environment.

How about this:
#define CFG_ENV_SECT_SIZE 0x40000 /* 256K(one sector (N)) for env */ #define CFG_ENV_ADDR (CFG_MONITOR_BASE - CFG_ENV_SECT_SIZE)
This way you only need to hardcode the sector size once.

Good idea. I will cleanup the patch and resubmit.
