Hi, I am trying to create/develop a device driver for the enhanced sd host controller driver for the mxc platform, specifically the mx27/35 platforms. This would provide a glue to the upper layers of u-boot i.e the MMC infrstructure and the filesystem layers. Since this will be a polling only driver unlike the one in Linux, has anyone tried working towards a mxc e-sdhc driver yet. I am currently looking at the linux driver for the same. Are there any quick guidelines for porting the interrupt based driver to a polling only driver in U-boot.
BTW, i have succesfully /implemented a SDHC driver from the scratch on the mxc platform earlier. Any comments/suggestions? Thanks in advance! -Stephanie.
