mtd: pxa3xx_nand: Don't alloc unneeded memory

2016-02-12T23:13:50+00:00

The allocation size is reduced from what was introduced from the
Linux kernel, as U-boot uses the statically allocated nand_info
instead of needing to dynamically allocate an mtd_info instance.

mtd: pxa3xx_nand: Correct offset calculation

2016-02-12T23:13:47+00:00

Correct some pointer math in initialization.  An offset was added
to a struct-typed pointer instead of one casted to a byte-size,
resulting in a much larger offset than intended.

mtd: pxa3xx_nand: Correct null dereference

2016-02-12T23:13:42+00:00

Correct a null pointer dereference in board_nand_init().  Zeroed
memory was allocated, then immediately dereferenced.  The
dereference is completely removed, since this pointer is later
initialized in alloc_nand_resources.

nand: mxs: fix error handling for mxs_nand_init

2016-02-12T23:10:15+00:00

Fix error handling for mxs_nand_init.

The original error handling is wrong for err2 and err1.
Should first free desc[x], then free desc.

This patch also correctly handle err3, should use
MXS_DMA_CHANNEL_AHB_APBH_GPMI0 as the check point.

atmel_nand: Add 32 bit ecc support for sama5d2 chip

2016-02-02T10:49:11+00:00

Also if minimum ecc requirment is bigger then what we support, then just
use our maxium pmecc support.
But it is not safe, so we'll output a warning about this.

atmel_nand: use the definition: PMECC_OOB_RESERVED_BYTES instead magic number

2016-01-27T12:58:59+00:00

As atmel_nand_ecc.h is sync with v4.1 kernel, which adds the
PMECC_OOB_RESERVED_BYTES. So use it in the driver.
