I'm using the same patch on a ep93xx based board using P30 flash. Works
great for me.

The only problem I found in the patch is in flash_hwr_init() the first:

+ 	__strata_info.base1 = (void *)CYGNUM_FLASH_BASE;

Should be removed. The __strata.info is only available #ifndef
CYGOPT_FLASH_IS_BOOTBLOCK. The .base1 is actually set correctly a bit
later in the code.

Hartley
