Subject: [PATCH] ARM: OMAP1: add MMC configuration for Palm Tungsten E
Date: Tue,  4 Dec 2018 19:58:12 +0200	[thread overview]
Message-ID: <20181204175812.2678-1-aaro.koskinen@iki.fi> (raw)

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.
