* powerpc/espi: remove 80us delay to improve transfer performanceHou Zhiqiang2014-06-05-32/+106
| | | | | | | Replace 80 mircoseconds delay with polling flag ESPI_EV_TXE. Signed-off-by: Hou Zhiqiang <B48286@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* powerpc: Fix CamelCase checkpatch warningsPrabhakar Kushwaha2013-08-20-1/+1
| | | | | | | | | | | 85xx, 86xx PowerPC folders have code variables with CamelCase naming conventions. because of this code checkpatch script generates "WARNING: Avoid CamelCase". Convert variables name to normal naming convention and modify board, driver files with updated the new structure.

* spi: Use spi_alloc_slave() in each SPI driverSimon Glass2013-03-19-3/+1
| | | | | | | | Rather than each driver having its own way to allocate a SPI slave, use the new allocation function everywhere. This will make it easier to extend the interface without breaking drivers. Signed-off-by: Simon Glass <sjg@chromium.org>
* powerpc/espi: remove write command length checkShaohui Xie2012-10-22-4/+2
| | | | | | | | | | | | Current espi controller driver assumes the command length of write command is not equal to '1', it was made based on SPANSION SPI flash, but some SPI flash driver such as SST does use write command length as '1', so write command on SST SPI flash will not work. And the length check for write command is not necessary for SPANSION, though it's harmless for SPANSION, it will stop write operation on flashes like SST, so we remove the check.
