Hopefully they can be convinced to > add support to mainline. I'm not sure if they can be convinced :( Anyway, what would be the preferred way to improve the xxx_esdhc in mainline U-Boot? Both, the Freescale U-Boot [1] and Barebox [2] have a imx-esdhc.c. With this, the options I see for mainline U-Boot are a) to port the Freescale/Barebox imx-esdhc.c changes/improvements into U-Boot's fsl_esdhc.c or b) create a new imx-esdhc.c in U-Boot, too. ?
