spi: Correct two error return values

2016-02-26T15:53:10+00:00

When an error number is provided we should use it, not change it. This fixes
the SPI and SPI flash tests.

One of these is long-standing. The other seems to have been introduced by
commit 1e90d9fd (sf: Move read_id code to sf_ops).

sandbox: spi: Remove an incorrect free()

2016-02-26T15:53:10+00:00

We must not free data that is managed by driver mode. Remove this line,
which is a hangover from the pre-driver-model code.

This fixes a problem where 'sf probe' crashes U-Boot if the backing file
for the SPI flash cannot be found.

sf: spi_flash: use dma to copy data from mmap region if platform supports

2016-02-23T10:44:46+00:00

Add dma memcpy api to the default spi_flash_copy_mmap(), so that
dma will be used to copy data when CONFIG_DMA is defined for the
platform.

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.
