Hi Haojian, I've tested your v4 series.

I can see this patch add support for MMC_ACMD51 > MmcDxe: expand to support multiple blocks > PL180: update for indentifying SD > PL180: set variable length for CMD6 and ACMD51 I can see this patch is fixing the data size for ACMD51. And it is only when this patch is applied that it starts to boot again. So I think they still need to be stacked or squashed differently so they are bisect-able, sorry. > > ArmPlatformPkg/Drivers/PL180MciDxe/PL180Mci.c | 29 +- > EmbeddedPkg/Include/Protocol/MmcHost.h | 29 ++ > EmbeddedPkg/Universal/MmcDxe/Mmc.h | 176 ++++++++++- > EmbeddedPkg/Universal/MmcDxe/MmcBlockIo.c | 175 +++++++---- > EmbeddedPkg/Universal/MmcDxe/MmcIdentification.c | 354 > +++++++++++++++++++++-- > 5 files changed, 669 insertions(+), 94 deletions(-) > > -- > 2.7.4 > _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
