Customer is using NOR Flash as the primary boot device and then switching over to raw NAND Flash. The driver being used for the NAND requires 4 Ready/Busy hardware lines, 1 for each of the physical Flash components. To set this up in the pin muxing, it looks like IFC_A29:31 become IFC_RB2:4 and these pins are no longer available for NOR Flash addressing.
Is this correct?
What is the largest NOR device that can be addressed assuming IFC_A29:31 are not available and used as RB2:4?
i.e. will using ADM mode 0 with a shift of 3 allow the use of a 2 ** 29 - 512 Mbit NOR Flash or is there some other limit?
