DMA: Split the APBH DMA init into block and channel init

2012-04-16T12:53:59+00:00

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

NOTE: This patch depends on:

onenand: Replace ONENAND_IS_MLC() with ONENAND_HAS_4KB()

2012-04-04T15:08:40+00:00

This replacement causes 4KB page size devices to work properly with u-boot.

The old ONENAND_IS_MLC() behavior has been preserved by explicit
setting of ONENAND_HAS_4KB_PAGE for those devices.

This change makes the onenand_base.c file more resembling the respective
kernel sources.

onenand:samsung Target dependent OneNAND chip probe function

2012-04-04T14:27:34+00:00

Separate callback for probing OneNAND memory chip.
If no special function is defined, default implementation will be used.

This approach gives more flexibility for OneNAND device probing.

cfi: fix the incomplete erased status check in buffer write

2012-03-21T15:25:33+00:00

Without the fix, flash_write_cfibuffer will terminate the erased
status check once an all-0xFF word has been found instead of
continuing the erased status check utill the first non-0xFF word.

mtd/nand:Fix wrong usage of is_blank() in fsl_ifc_run_command

2012-02-28T20:03:39+00:00

Freescale IFC NAND Machine calculates ECC on 512byte sector and same is used in
fsl_ifc_run_command() during ECC status verification. Also this sector is passed
to is_blank() for blank checking. It is wrong at first place because
is_blank()'s implementation checks for Page size and OOB area size.
is_blank() should be called per page for main and OOB area verification.

Variables name are redefined to avoid confusion between buffer and ecc sector.
