* EmbeddedPkg: Fix build error for MmcDxePierre Gondois2020-07-231-3/+3
| | | | | | | | | | | | | | | | | | | The following command line: build -b NOOPT -a IA32 -t VS2017 -p edk2\EmbeddedPkg\EmbeddedPkg.dsc Generates the following error: MmcDxe.lib(Diagnostics.obj) : error LNK2001: unresolved external symbol __allshl MmcDxe.lib(Diagnostics.obj) : error LNK2001: unresolved external symbol __aullshr MmcDxe.lib(MmcBlockIo.obj) : error LNK2001: unresolved external symbol __allmul These erros are due to the use of shift/multiply operations on UINT64 variable on a IA32 architecture.

* EmbeddedPkg/MmcDxe: Added MaxBlock Transfer Limit 65535 in R/W.Gaurav Jain2020-06-121-11/+23
| | | | | | | | | | | | | | | | | | | | Moved BlockCount calculation below BufferSize Validation checks. First Ensure Buffersize is Not Zero and multiple of Media BlockSize. then calculate BlockCount and perform Block checks. Corrected BlockCount calculation, as BufferSize is multiple of BlockSize, So adding (BlockSize-1) bytes to BufferSize and then divide by BlockSize will have no impact on BlockCount. Reading Large Images from MMC causes errors. As per SD Host Controller Spec version 4.20, Restriction of 16-bit Block Count transfer is 65535. Max block transfer limit in single cmd is 65535 blocks. Added Max Block check that can be processed is 0xFFFF. then Update BlockCount on the basis of MaxBlock.

* EmbeddedPkg: Fix Command Argument for SD/eMMC R/W operation.Meenakshi Aggarwal2019-01-301-5/+16
| | | | | | | | | | | | | | | | | | 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.

* EmbeddedPkg/MmcDxe: Card Presence Detect Race Conditionoliviermartin2011-08-301-80/+76
| | | | | | | | | | | | | | | | | | | | | | 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.
