In the attached patch you can see the progress of my work in the NAND rewrite.

This is not suitable for inclusion yet.

I tried it with a flash with no bad blocks. With the attached patch it worked for booting from JFFS2, and erasing/writing new JFFS2 images. My system copies the boot partition to RAM and U-Boot's JFFS2 uses the RAM copy.

The patch just fixes my configuration file and makes cmd_nand.c build when CONFIG_MTD_NAND_UNSAFE is not defined.

Things that work now:

1. Correct handling of bad blocks.

I only tried a nand with no bad blocks. I'll simulate some bad blocks when the read.jffs2 support is added.

2. NAND boot works

not tried

4. Direct to NAND tftp/nfs support.

not tried

Things that are probably borked:

1. Multiple chip support (I don't have such hardware available and the previous code was kinda of unclear.

not tried (I don't have the hardware either.)

3. JFFS2 support although there is probably b0rken.
4. The read.xxx/write.xxx support is just not there yet.

I need to be able to specify the range of NAND to read from (like read.jffs2 does), then I will test the JFFS2 read/write with bad blocks.
