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
