From 1c1e70fa6e1e986992afbb282d048483cbe0b319 Mon Sep 17 00:00:00 2001 From: oliviermartin Date: Mon, 4 Jul 2011 10:02:49 +0000 Subject: ArmPkg/BdsLib: Linux kernel supports either FDT or ATAG If a FDT blob is passed to the kernel it is required we can load it. If we fail to load the binary then we must abort the Linux booting process. ArmPkg/CpuDxe: Ensure the reset vector passed to the CP15 VBAR register is aligned on the right boundary git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11968 6f19259b-4bc3-4df7-8a09-765794883524 --- ArmPkg/Drivers/CpuDxe/Exception.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'ArmPkg/Drivers/CpuDxe') diff --git a/ArmPkg/Drivers/CpuDxe/Exception.c b/ArmPkg/Drivers/CpuDxe/Exception.c index 2f7e1b637f..55a7132193 100644 --- a/ArmPkg/Drivers/CpuDxe/Exception.c +++ b/ArmPkg/Drivers/CpuDxe/Exception.c @@ -206,10 +206,13 @@ InitializeExceptions ( //Note: On ARM processor with the Security Extension, the Vector Table can be located anywhere in the memory. // The Vector Base Address Register defines the location - ArmWriteVBar(PcdGet32(PcdCpuVectorBaseAddress)); + ArmWriteVBar (PcdGet32(PcdCpuVectorBaseAddress)); } else { + // The Vector table must be 32-byte aligned + ASSERT(((UINT32)ExceptionHandlersStart & ((1 << 5)-1)) == 0); + // We do not copy the Exception Table at PcdGet32(PcdCpuVectorBaseAddress).
