proposed patch add support of NOR flash arrays to cfi driver
Supported arrays split by address (example: first on offset 0, second on offset 0x400000) and interleaved (example: two devices
with 16bit width, mapped to 32bit word)
Tested on simple cfi flash and on Samsung K8Q2815UQB which have two 8M devices selected by A22 pin.
I will be very glad if someone help me with testing on interleaved or split+interleaved array.
Wait for you questions and recommendations.
P.S. Also driver have CFI_AMD_BYPASS flag which enable AMD type flash to program word with 2 bus access instead of 4 by default.
