Bug Description

I configured my TC2 to boot from the A7 cluster, rather than the A15 cluster.

board.txt:
SCC: 0x700 0x1032F003 ;booting from the A7 cluster

ArmPlatformPkg/ArmVExpressPkg/ArmVExpress-CTA15-A7.dsc
gArmTokenSpaceGuid.PcdArmPrimaryCore|0x100
gArmTokenSpaceGuid.PcdGicPrimaryCoreId|0x100

Then rebuilt the code.

TC2 fails when trying to create a directory:
2.0 Shell> mkdir fs0:\test3
MciWriteBlockData(): TX buffer Underrun! Response:0xA4040AE Status:0x50, Number of bytes written 0x8
ASSERT /linaro/uefi/master/uefi-next.git/ArmPlatformPkg/Drivers/PL180MciDxe/PL180Mci.c(342): 0

If I use a directory created previously when booted from the A15 core, creating a file also fails:
2.0 Shell> edit fs0:\test\test.txt
MciWriteBlockData(): TX buffer Underrun! Response:0xA4040AE Status:0x50, Number of bytes written 0x8
ASSERT /linaro/uefi/master/uefi-next.git/ArmPlatformPkg/Drivers/PL180MciDxe/PL180Mci.c(342): 0

This works fine when booting with the A15 cluster.

I also tried this with an A15x2 RTSM, and it also failed:

2.0 Shell> mkdir fs0:\test
MciWriteBlockData(): Data End timeout Number of words written 0x80
MciWriteBlockData(): Data End timeout Number of words written 0x80
MciWriteBlockData(): Data End timeout Number of words written 0x80
Directory 'fs0:\test' unable to create.

Steven Kinney is seeing timing issues with Arndale, perhaps this is related?
