Hi Rafael & Eugene,
Normally the EmbeddedPkg/Universal/MmcDxe should support MMC / SD(HC) (and I
have just pushed eMMC support - svn 15074). It has been tested with
different MMC/SD/eMMC controllers (ARM PL180 controller / BeagleBoard /
PandaBoard / Exynos / a eMMC controller) and it seems to work.
To use EmbeddedPkg/Universal/MmcDxe, you need to implement
EFI_MMC_HOST_PROTOCOL for your eMMC host controller.
Thanks,
Olivier

Like any mass storage device, a driver that products the Block IO protocols
should be all that is required.
edk2 has a driver from ARM for their proprietary MMC host controller. Many
other systems use the industry standard SD Host Controller (SDHC) but I am
not aware of an open source driver being available for SDHC at this time.

Subject: [edk2] Getting information from eMMC device
Hi everyone
I need to check some information on an eMMC storage device.
I still don't have this device here, so I'm trying to do some research
before receiving it.
As far as I could check, there is no specific protocol to access this kind
of device. Does any of you have already worked with eMMCdevices at UEFI ? Is
there any specific protocol to access this kind of device ?
Thanks
Rafael R. Machado
