Hi Wolfram: Here are the patches that I changed the codes refer to your previous comments. The data IO and WP func are verified on the i.MX51 BBG board. The missing bits of the HOST_CONTROL and so on had been complemented in 4-3 patch. Hi Uwe: The MSL specifed part code is still on-going. I would change them to the "dynamically allocated method" later. Any review/comments and suggestions are appreciated. Thanks in advanced. [4-1] sdhci/sdhci-pltfm common codes modifications when support FSL eSDHC driver. [4-2] MX51 MSL codes modification. [4-3] i.MX sdhci driver seperated from MPC esdhc driver.
