The following patches take the work by Daniel Kochmánski, and make some heavy modifications for readability and functionality, based on Boris Brezillon's Linux driver. Tested on an Olimex Lime w/ A20. Patches are sent as RFC. Open questions:
- Config options added are partially NAND-chip specific. Some options can
be autodetected based on the NAND ID, others require either brute-forcing or config options like these. Do they belong in sunxi-common? Should we make a Kconfig option for this? If bikeshedding is desired, are defines in sunxi-common.h good enough for now?
- Style is mostly kernel-like. Satisfied?
- Daniel: do you think we can work from here?
Please comment away!
Cool stuff. Overall this looks good I'll reply with more detailed feedback to your individual patches, 2 questions:
1) Can you provide a quick howto (at developer level) on how to actually get the spl and u-boot into the nand, what I'm looking for is unstructions like this:
a) Take this git repo + branch, build a kernel from it b) Look at this dts file for a nand settings example, adjust it for your board c) Once booted into the kernel using an updated dts you should have these block devices, dd spl to this one, and u-boot to this one.
No more to go more detailed then that :)
2) What is the plan to add support for loading files from nand in u-boot proper, so that we can get (e.g.) extlinux.conf + kernel +dtb from a /boot on nand ?
