* omap_gpmc: add support for hw assisted BCH8Andreas Bießmann2013-04-08-1/+1
| | | | | | | | | | | | | | | | | | | | | | The kernel states: ---8<--- The OMAP3 GPMC hardware BCH engine computes remainder polynomials, it does not provide automatic error location and correction: this step is implemented using the BCH library. --->8--- And we do so in u-boot. This implementation uses the same layout for BCH8 but it is fix. The current provided layout does only work with 64 Byte OOB.

* | Roll crc32 into hash infrastructureSimon Glass2013-02-28-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the CRC32 algorithm to the list of available hashes, and make the crc32 command use hash_command(). Add a new crc32_wd_buf() to make this possible, which puts its result in a buffer rather than returning it as a 32-bit value. Note: For some boards the hash command is not enabled, neither are sha1, sha256 or the verify option. In this case the full hash implementation adds about 500 bytes of overhead. So as a special case, we use #ifdef to select very simple bahaviour in that case. The justification for this is that it is currently a very common case (virtually all boards enable crc32 but only some enable more advanced features). Signed-off-by: Simon Glass <sjg@chromium.org>

| * tegra: add SPI SLINK driverAllen Martin2013-02-11-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add driver for tegra SPI "SLINK" style driver. This controller is similar to the tegra20 SPI "SFLASH" controller. The difference is that the SLINK controller is a genernal purpose SPI controller and the SFLASH controller is special purpose and can only talk to FLASH devices. In addition there are potentially many instances of an SLINK controller on tegra and only a single instance of SFLASH. Tegra20 is currently ths only version of tegra that instantiates an SFLASH controller. This driver supports basic PIO mode of operation and is configurable (CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4 devices per controller may be attached, although typically only a single chip select line is exposed from tegra per controller so in reality this is usually limited to 1. To enable this driver, use CONFIG_TEGRA_SLINK Signed-off-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
