It never really took the size to be written -- the size was implicitly one page before. It looks like there may have been a bug in the old code, where common code expected a size to be there anyway, even though it was ignored other than for error checking. -Scott

Do you want me to rephrase the commit log or will you take it as is ? Eric

- commit 418396e212b59bf907dbccad997ff50f7eb61b16 chenged the behaviour of nand write.raw which now takes a pagecount as a parameter and no more the size to be written so update the default environment of these boards to fix the problem. - tested on a mx28evk with a 4k page NAND and on a custom board with a 2k page NAND.
