[U-Boot-Users] New NAND code draft

[U-Boot-Users] New NAND code draft

[Pantelis Antoniou]

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:
