I have been working on u-boot for p4080ds board. Where can I find Nor Flash Read/Write routine in u-boot?
Please refer to the u-boot/include/mtd/cfi_flash.h
I have seen read,write other needed routines in u-boot/include/mtd/cfi_flash.h. I want to also know how chip select 0-7 are drived. In default, chip select 0 is changed during read/write from nor flash. I want to also drive chip select 1 which is always high. How to make it low? What would you suggest for that?
How to assert/negate LCS_B[n] where n can be 0-7? It is observed that only LCS_B is asserted and negated. In addition, I want to also assert/negate LCS_B signal. How can I do that?
