| | * mxc: Fix SDHC multi-instance clockBenoît Thébaudeau2012-10-16-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not suitable for the multi-instance use case (initialization made directly with fsl_esdhc_initialize()). This patch fixes this issue by adding a configuration field for the SDHC input clock frequency.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch prevents dcache-related problem. The problem manifested itself on the SPI driver, this is just a port to the MMC driver. The scenario is the same. In case an "mmc read" is issued to a buffer which was written right before it and data cache is enabled, the cache eviction might happen during the DMA transfer into the buffer, therefore corrupting the buffer. Clear any cache lines that might contain the buffer to prevent such issue.
