I'll have to migrate over to booting off the NAND from the Dataflash I'm booting off of now. Having the SD card in the slot during early boot hangs because on this board both the SPI0 dataflash and the MMC are hard wired to the same, well, wires. This means I should get the nand and nandfs stuff working on this board as well, so I can boot off of its 256MB flash.
Plus I need to get back to refactoring. After editing board_sam9260ek.c I can see that I need to extend the AT91RM9200 device stuff I've done to the sam9260 (and sam9g20). But I'm not sure how far I want to go down that path. But we need some way to have a generic pin mux system. Linux has a fine example.
However, I think that many of the issues that I'm running into may be solved by moving to device-tree stuff. Other ARM ports support this now, and Linux is moving that way. Newer Atmel CPUs will have DTS files. All boards supported by Linux appear to be getting DTS files to replace the custom code for each board. It seems that this is a good way to go. AT91RM9200 is the only one that seems to not have dts files, so I may need to write those from scratch.
But the bottom line is that I'm excited. I'd given up hope on this board, and now it is booting. Woo hoo!
