[U-Boot-Users] New NAND code draft
Hi there
In the attached patch you can see the progress of my work in the NAND rewrite.
This is not suitable for inclusion yet.
Things that work now:
1. Correct handling of bad blocks. 2. NAND boot works 3. Updated to latest MTD snapshot. 4. Direct to NAND tftp/nfs support.
Things that are probably borked:
1. Multiple chip support (I don't have such hardware available and the previous code was kinda of unclear. 2. Since there is DOC support in u-boot that utilizes the old code and definitions I left the linux/mtd/nand.h header in place, and created a new mtd_nand.h header for the new stuff. 3. JFFS2 support although there is probably b0rken. 4. The read.xxx/write.xxx support is just not there yet.
I would appreciate it if you could take a look and report back to me.
Regards
Pantelis

It doesn't even compile for me:
