Hope you are referring CONFIG_RTC_DRV_TWL92330 to omap3_defconfig
and not to omap_4430sdp_defconfig.
Sorry I meant CONFIG_RTC_DRV_TWL4030 in the omap_4430sdp_defconfig.
If you take that out, MMC is never detected.
Even disabling CONFIG_RTC_DRV_TWL4030 in omap_4430sdp_defconfig, card gets
detected
always on booting up.
With omap_4430sdp_defconfig , I've tested on 4430SDP and Blaze and always
Cards on MMC1 & MMC2 gets detected once bootedup.
Are you able to actually mount root on the MMC with let's say
current linux-omap master branch?
Yes I booted with file system mounted on card present on MMC1,
and I can see cards getting detected properly and also filesystem gettting
mounted.
Here are the boot logs with "CONFIG_RTC_DRV_TWL4030 " disabled and
filesystem
on ext2 partition of card present on MMC1

>Also MMC is never detected with omap3_defconfig.
With omap3_defconfig + disabling "CONFIG_OMAP_RESET_CLOCKS",
I've tested on 4430SDP and Blaze and always Cards on MMC1 & MMC2
gets detected on bootup.
That should be fixed so CONFIG_OMAP_RESET_CLOCKS works. Otherwise
we're relying on some random clocks being enabled.

Following is the commit ID :1674c0ceabfb7726246989874bb4da7bcb55ea89
used on LO master branch for testing. All the patches were merged.
OK, thanks for checking that.
