This series tests raw nand flash in sandbox and fixes various bugs discovered in
the process. I've tried to do things in a contemporary manner, avoiding the
(numerous) variations present on only a few boards. The test is pretty minimal.
Future work could test the rest of the nand API as well as the MTD API.
Bloat (for v1) at [1] (for boards with SPL_NAND_SUPPORT enabled). Almost
everything grows by a few bytes due to nand_page_size. A few boards grow more,
mostly those using nand_spl_loaders.c. CI at [2].

Changes in v2:
- Don't set load->priv for spl_nand_legacy_read since it doesn't use it.
- Rename SYS_NAND_PAGE_COUNT to SYS_NAND_BLOCK_PAGES
- Remove spurious form feed character
- Use ECC bytes from the layout, since we already are using the layout for the
ECC byte position.
- Add some documentation for the device tree binding
- Fix unused expression warning with clang
Sean Anderson (15):
spl: nand: Fix NULL-pointer dereference
nand: Don't dereference NULL manufacturer_desc
nand: Calculate SYS_NAND_BLOCK_PAGES (neé SYS_NAND_PAGE_COUNT)
