* EmbeddedPkg: Fix Command Argument for SD/eMMC R/W operation.Meenakshi Aggarwal2019-01-301-0/+2
| | | | | | | | | | | | | | | | | | Issue : SD read failure for high capacity cards e.g. 64 GB Reason : Command argument value exceeds 32 bit for block number 0x3787FFF and cant be fit into 32 bit wide SD host controller register. Fix : AccessMode bits [29:30] of OCR is a valid definition to calculate data address for eMMC cards. For SD cards, data address is calculated on the basis of card capacity status bit[30] of OCR.

* SD : Updated CMD 6 implememtation.Meenakshi Aggarwal2017-09-071-0/+8
| | | | | | | | | | | | | | | | | For setting high speed in SD card, First CMD 6 (Switch) is send to check if card supports High Speed and Second command is send to switch card to high speed mode. In current inplementation, CMD 6 was sent only once to switch the card into HS mode without checking if card supports HS or not, which is not as per specification and also we are not setting the HS i.e. 50000000 but directly asking the card to switch to 26000000 which is incorrect as SD card supports either 25000000 or 50000000.

| | | | | | | | | | | | | | | | Add the interface to change the bus width and speed. By default, MMC is initialized with 1-bit mode and less than 400KHz bus clock. It causes MMC working inefficiently. Set I/O bus width on both MMC controller and EXTCSD. Otherwise, it may cause unmatched failure case. And support more timing mode, high speed, HS200 & HS400 mode.

* EmbeddedPkg/MmcDxe: Card Presence Detect Race Conditionoliviermartin2011-08-301-0/+11
| | | | | | | | | | | | | | | | | | | | | | 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.
