2013-03-14MmcDxe: fixes sd card identification on pandaOlivier Deprez
It is observed with few SD cards that the protocol is hanging after issuing cmd5 and before cmd8. Adding a small delay inbetween recovers and driver bring up is continuing without problem.

2012-10-19EmbeddedPkg/MmcDxe: Ensure MMC is in Identification Modeoliviermartin
This change ensure the MMC card is in Identification Mode. The card might be in Data Transfer Mode if a pre UEFI Boot Loader had initialized the card. A potential optimization would be to skip the Identification Mode in this case.

2011-09-01EmbeddedPkg/MmcDxe: Add 'This' pointer attribute to protocol functionoliviermartin
This attribute allows the EFI_MMC_HOST_PROTOCOL interface to manage multiple instances in one driver. EmbeddedPkg/MmcDxe: Add Revision attribute to the EFI_MMC_HOST_PROTOCOL Note: The ARM PL180 and Omap35xx MMC host drivers has been updated. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12255 6f19259b-4bc3-4df7-8a09-765794883524
2011-08-30EmbeddedPkg/MmcDxe: Card Presence Detect Race Conditionoliviermartin
The MMC driver defaults to assume a card is not present. It then starts a timer in MmcDxeInitialize to check for card presence every 200ms. However it does not immediately check to see if a card is present so if the EFI driver connection process occurs less than 200ms after the driver load, the connection process for partition or filesystem drivers will fail because MediaPresent still is FALSE. To resolve this race condition, we need to immediately perform the presence check in the Start routine. EmbeddedPkg/MmcDxe: Media ID Handling Initialize the MMC device on Start or when presence changes instead of doing it on the Block IO calls. This way the layered drivers can be stopped and rebuilt with new Media IDs instead of experiencing errors on calls to Block IO.
