This patch adds support for NAND FLASH on the TQM8548. It is disabled by default and can be enabled for the TQM8548 modules. Note that the R/B pin is not supported by that module requiring to use the specified maximum delay time.
Note: With NAND support enabled the size of the U-Boot image exceeds 256 KB and TEXT_BASE must therefore be set to 0xfff80000 in config.mk, doubling the image size :-(.
What does this do differently from the code in drivers/mtd/nand/fsl_upm.c?
Maybe it does not support multi banks on a NAND chip. I have to check.
How much of this is board-specific?
Well, I already gave drivers/mtd/nand/fsl_upm.c a try but was unable to get it working on this board. Therefore I decided to keep this known to work driver which we have already for a while.
With Linux, I had more success.
