The parentheses in the macro definition are not matched. How about "... (PcdGet32 (PcdSdMmcGenericTimeoutValue))"? Could you help to verify the patch before sending it out?

I think the patch is missing the PcdLib reference in files SdMmcPciHcDxe.h and SdMmcPciHcDxe.inf. 5. The patch is also missing the PcdSdMmcGenericTimeoutValue PCD reference in SdMmcPciHcDxe.inf. Please follow other INF files in edk2 to add the PCD reference. Also please help to verify the patch before sending it out. Thanks in advance. 6. When adding a new PCD in DEC file, please also help to update the UNI file as well. Could you help to add below lines in file MdeModulePkg.uni: #string STR_gEfiMdeModulePkgTokenSpaceGuid_PcdSdMmcGenericTimeoutValue_PROMPT #language en-US "SD/MMC Host Controller Operations Timeout (us)." #string STR_gEfiMdeModulePkgTokenSpaceGuid_PcdSdMmcGenericTimeoutValue_HELP #language en-US "Indicates the default timeout value for SD/MMC Host Controller operations in microseconds."
