Cohen, Eugene 5811eea0fd ArmPkg: update CpuDxe to use CpuExceptionHandlerLib
Use the new ARM/AArch64 implementation of the base
CpuExceptionHandlerLib library from CpuDxe to centralize
exception handling.

oliviermartin 1c1e70fa6e 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

oliviermartin 6e88239331 ArmPkg/CpuDxe: ZeroMem the gExceptionHandlers[] array
Prevent an IRQ (or any other exceptions) to make a call to an undefined
handler when the interrupt handler has not been registered yet.

oliviermartin d7b6c49b78 ArmPkg/CpuDxe: Change chain of dependency for CpuDxe and PL390Gic
Previously the CPU driver had a dependency on the GIC driver.
But by design is should be the opposite. The CPU driver installs the
CPU protocol that exposes the exception registration function.
And then, the interrupt controller registers its IRQ handler through
this interface.

oliviermartin f0fef790ff ArmPkg: Introduce ArmSetLowVectors/ArmSetHighVectors functions
These functions set/clear the SCTLR.V bit that controls the location
of the Vector Table.
This commit also forces the SCTLR.V to be clear when the VBAR register
is set.

Note: The original fix has been proposed by Eugene Cohen (HP).

oliviermartin eeec69c5dc ArmPkg: Introduce the PCD PcdDebuggerExceptionSupport
The Exception Vector can be set before installing the CPU DXE driver to add
debugger support at the early stage of the firmware initialization.
If no one has touched the exception vector prior to the CPU DXE then the Vector
might contain non zero data.

AJFISH 225290eba7 Added new PeCoffGetEntryPoint lib function to get size of PE/COFF header. This is needed for debug prints with PE/COFF images that started as ELF or Mach-O. Moved and debugged ARM semihosting lib for RVD that prints out the debugger symbol load commands in a window on the debugger. Trying to write a script file, but that crashes RVD. Added debug print to BeagleBoard Sec that prints out RVD debugger command to load symbols for the Sec. Synced the rest of the code.

AJFISH d213712d4f Fixed a bug in the HardwareInterrupt handler that would blow the stack if you reenable interrupts in the TimerHandler. It should be noted this happens as the TimerHandler raises and restores TPL for the timer tick used by the DXE Core. There was some work around code in the CPU driver to prevent interrupts from being enabled while handling exceptions. This has been removed.

AJFISH 2ef2b01e07 Adding support for BeagleBoard.
ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers.
EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell.
BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine).
