Remove small amount of MDEPKG_NDEBUG dependent code which is no longer needed, given update of 'null' debug macros in ae83c6b7fd83a5906e016a32027c1bcd792a624e to explicitly mark debug-only code as discarded. Additionally, correctly mark as STATIC the two arrays within the updated code block. Signed-off-by: Mike Beaton <mjsbeaton@gmail.com>

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout EmbeddedPkg.

2020-06-12EmbeddedPkg/MmcDxe: Added MaxBlock Transfer Limit 65535 in R/W.Gaurav Jain1-11/+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.

In EDK2, identifiers carrying the EFI prefix are reserved for ones that are defined in the UEFI or PI specifications.

2019-10-09EmbeddedPkg/Universal/MmcDxe: "fix" CloseProtocol() call in BindingStop()Laszlo Ersek1-2/+3
The 3rd and 4th parameters of the CloseProtocol() call are wrong. Given that we're not dissociating a child controller from a parent controller (= closing a BY_CHILD_CONTROLLER open), but closing a BY_DRIVER open, the 4th parameter (ControllerHandle) should equal the 1st parameter (Handle). It's unclear why this code hasn't crashed before. Note that the patch doesn't fix the underlying driver model bug. I don't understand what the loop in MmcDriverBindingStop() attempts to do. Is this driver supposed to be a bus driver? It seems to create new handles, and to append device path nodes. But it doesn't set up proper parent/child protocol opens, and it doesn't close them.

If SD doesn't support SD_HIGH_SPEED, function should still continue to setup SD to go into 4 bits more if it is supported. Currently, the code inadvertently exits early, but with a EFI_SUCCESS return code, and so execution proceeds without ever attempting to enable 4-bit mode.

2011-08-30EmbeddedPkg/MmcDxe: Card Presence Detect Race Conditionoliviermartin3-80/+95
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.
