dm: spi: Read default speed and mode values from DT

2016-07-09T14:46:34+00:00

In case of DT boot, don't read default speed and mode for SPI from
CONFIG_*, instead read from DT node. This will make sure that boards
with multiple SPI/QSPI controllers can be probed at different
bus frequencies and SPI modes.

env: use cache line aligned memory for flash read

2015-08-17T17:59:14+00:00

Use memalign() with ARCH_DMA_MINALIGN to allocate read buffers.
This is required because, flash drivers may use DMA for read operations
and may have to invalidate the buffer before read.

env_sf: Fix recovery default

2015-04-07T12:41:10+00:00

The u-boot environment is redundantly stored in a NOR flash on our boards.
Redundant means that there are two places to store the environment. But only
one of the two is active. I discovered that on one board the u-boot (env_sf)
uses the environment from the second place and the Kernel (fw_printenv) uses
the environment from the first place.
To decide which is the active environment there is a byte inside the
environment. 1 means active and 0 means obsolete. But on that board both
environments had have a 1. This can happen if a power loss or reset occurs
during writing the environment. In this situation the u-boot (env_sf)
implementation uses the second environment as default. But the Kernel
(fw_printenv) implementation uses the first environment as default.

This commit corrects the default in the u-boot env_sf implementation when a
problem was detected. Now the recovery default is the same like in all other
environment implementations. E.g. fw_printenv and env_flash. This ensures that
u-boot and Kernel use the same environment.

dm: Add spi.h header to a few files

2014-10-22T16:36:47+00:00

Some files are using SPI functions but not explitly including the SPI
header file. Fix this, since driver model needs it.

env: Add env_export() wrapper

2014-03-21T20:43:59+00:00

Implement env_export() wrapper, so that all implementers of saveenv() don't
have to call hexport_r(), crc32() etc. sequence . This trims down a bit of
code duplication.

SPL: P2020RDB: fix the problem booting from spi flash

2014-02-24T23:23:19+00:00

There was no enough stack in SPL, so the buffer needed in SPL is to malloc
from memory pool and to repalce the temporary variable.
