[ECOS] Multiple banks of Intel strataFlash?

[Chris Lesiak]

Does ecos support multiple banks of Intel strataFlash?

My configuration is:

An Intel SA1110 with four Intel 28F128J3 parts.  These are 16bit wide
128Mbit (16MByte) devices that will be arranged in two 32bit wide banks
of 32MBytes each for a total of 64MBytes.  The first bank will start at
physical address 0x02000000 and the second bank will start at
0x08000000.

Thanks,

Probably the best thing would be to arrange the memory map such that these
two banks end up contiguous [in logical memory] using the MMU.  Note that
the SA11x0 variant already moves the FLASH around, so this will not be a
big deal.  Once this is in place, some simple additions to the StrataFlash
driver will handle it for you.
