Hi Scott,

Does this kind of page-splitting only apply to the IPL and nothing
else?  If so, it seems that if:

1. modifications are made to U-Boot's fsl_elbc_nand driver similar to
Liu Shuo's kernel mods, and
2. an option is added to generate u-boot-nand.bin with its IPL split
into two 2k chunks

then we can boot and run entirely from a 4k page device on MPC 83xx, correct?

That would be very good news, as it seems that [some] 2k NAND parts
are starting to go EOL.

Thanks!
