DEVCONTROL0,1 needs to be modelled in DT-only boot as well. OMAP243X SDP # md.l 0x490022e8 1 490022e8: 002fff80 ../. OMAP243X SDP # md.l 0x49002274 1 49002274: 04000000 .... OMAP243X SDP # mw.l 0x490022e8 802fff80 ^^ bit 31 is step (a) below OMAP243X SDP # mw.l 0x49002274 05000000 ^^ bit 24 is step (b) below OMAP243X SDP # md.l 0x49002274 1 49002274: 05000000 .... OMAP243X SDP # md.l 0x490022e8 1 490022e8: 802fff80 ../. OMAP243X SDP # boot happily detects the mmc partitions. http://slexy.org/view/s21QaCLMWQ we modelled pbias in dt so far - this is necessary, but two other steps are needed as well (based on arch/arm/mach-omap2/hsmmc.c used in non-dt boot): a) OMAP243X_CONTROL_DEVCONF1:: OMAP243X_MMC1_ACTIVE_OVERWRITE should be tweaked based on vdd b) OMAP2_CONTROL_DEVCONF0::OMAP2_MMCSDIO1ADPCLKISEL should be set for internal_clk (sdp2430). -- Regards, Nishanth Menon
