[PATCH] ARM: OMAP1: add MMC configuration for Palm Tungsten E

From: Aaro Koskinen
Date: Tue Dec 04 2018 - 12:58:34 EST


Add initial MMC configuration for Palm Tungsten E to allow using a proper
rootfs on the device. This still assumes the bootloader enabling the MMC,
and that the card is always present and writeable.
