[PATCH v2 0/2] fix partial spl nand reads

NAND reads are done on a per-page basis. Scenarios that attempt to read
less than a page will find their memory has been clobbered by the NAND
read.

Allocate a buffer for the NAND page, and only overwrite the memory that
the user requested.


This is a continuation of [1], since there is now a cover letter and
multiple patches.

v2:
    Add cover letter
    Add Dario reviewed to patch 2
    Add patch 1 to move the buffer to the heap
    Add my own apologies for taking me so incredibly long to fix this
    patch up and resubmit.



Colin Foster (2):
  mtd: rawnand: nand_spl_loaders: move nand page buffer to heap
  mtd: rawnand: nand_spl_loaders: allow partial nand page reads during
    nand_spl_load_image
