Hello All,
I'm working on a new port of U-Boot to a custom board and have a few questions.
Is Nand flash actually supported by U-Boot? I've been looking through the sources and could not find any references to Nand flash. I don't believe that Nand flash is supported but wanted to make sure prior to jumping in.
Also, it seems like all of the code that would access flash, does it simply by reading from the address that the flash is located at. Although, this works for other flash types (ie. Intel Strataflash) this will not work for Nand flash.
Would there be any objection to adding a read_flash function to the flash drivers so that the type of flash being used is generic?
The nand flash driver that I write will be cpu/ppc4xx/440ep_ndfc.c as the 440ep has a Nand Flash Controller on it in addition to the board/x/flash.c that contains the flash protection and serial reading code.
I want to eventually get patches to all the work to get the board and processor working back into U-Boot so please let me know if I should be doing any of the above items in a different manner.
Regards,
