Maybe a README.corenet_ds (or > board/freescale/corenet_ds/README), that points to README.pblimage? [S.H] Yes. A README for corenet_ds board will be more useful, then a ramboot section points to README.pblimage.

[S.H] we do have these soft-boot instructions for corenet_ds board. And yes, they should go in README of corenet_ds board, but seems we don't have such a README.
