As discussed in our meeting today, I have submitted a BZ for the kernel boot
from MMC issue:
https://bugzilla.redhat.com/show_bug.cgi?id=860855
A patch that includes the config changes we tested is attached to the BZ.
They are based on the last known-good (booting) kernel for OMAP and Tegra.
If these are acceptable, will someone with commit privileges please apply
the changes and push it out. If you prefer to submit a scratch build of the
changes first (which I recommend), Paul Whalen and I will be happy to test
the resulting images to confirm they work as expected.
Please reply with any questions or comments.
I have some issues with it. For example why do you enable these:
+CONFIG_MMC_SPI=m
+CONFIG_MMC_USHC=m
when they're not used by OMAP, similarly the following aren't even
part of a tegra platform
+CONFIG_MMC_SDHCI_PXAV3=m
+CONFIG_MMC_SDHCI_PXAV2=m
What's more dgilmore and I were discussing the following change:
+CONFIG_DMADEVICES=y
+CONFIG_DMA_OMAP=m
Which resulted in a booting system as can be seen here:

I'm building a scratch kernel now for OMAP to see if it works (it also
has some other OMAP changes) and once has been tested we can move onto
the likely similar fix for tegra.
