What sort of image am I supposed to get > when I build "P5040DS_NAND"? Where is the PBI? [S.H] there is already a readme for p3041/p5020/p4080 (doc/README.pblimage), With the PBL tool, we will get a ramboot image "u-boot.pbl". and also the PBI, it is shared by P3/P4/P5.

With SPL we could use > CONFIG_NAND_ENV_DST (which has some issues, but they're fixable). [S.H] this will need export some NAND read APIs (like load ENV stuff from CONFIG_NAND_ENV_DST), then they can be reused before relocation even not using SPL. Please suggest. > > It would also be nice to include instructions for configuring the board > to boot from NAND in a README [S.H] This exist in the above readme.

[S.H] I was told that when doing ramboot, I should not assume the board has a NOR flash, for ex. on customer's board, they may only have NAND. So I did not do this.
