Flash support for the 28F640J3A



I am trying to add FLASH support for a StrongARM
SA1110 connected to (2) 28F640J3A Flash chips.  I have
been looking at the assabet_strataflash.inl file.

There are no 64Mbit or 8MB examples, but for
the 28F320J3A, there is the line:

#define CYGNUM_FLASH_BASE_MASK (0xFE000000u)

Question 1:
   For the 28F640J3A, should this line read:

#define CYGNUM_FLASH_BASE_MASK (0xFB000000u)

Question 2:
   Why is the line for 8 MB not:

#define CYGNUM_FLASH_BASE_MASK (0xFC000000u)
I don't follow why the 24th bit is set/masked here.

Warren
