In order to be able to produce meaningful diagnostic output when taking synchronous exceptions that have been caused by corruption of the stack pointer, prepare the EL0 stack pointer and switch to it when handling the 'Sync exception using SPx' exception class.

# Instance of CpuExceptionHandlerLib Library for ARM/AArch64 architectures
|
|
#
|
|
# This library instance is used for modules that will implement exception
|
|
# handlers in-place (by programming VBAR). The exception handlers will be
|
|
# generated with alignment as required by the processor architecture. The
|
|
# alignment must be propagated into the parent FFS/FV through FDF build rules
|
|
# for the relevant module types (i.e. Align=Auto).
|
|
#
|
|
# Note that using this library instance can cause growth to the size of the FV
|
|
# due to the padding added by the build tools to meet the vector alignment
|
|
# requirements and may not be desirable for space-sensitive FVs (uncompressed /
|
|
# XIP components). The alternative library instance, ArmRelocateExceptionLib
|
|
# should be considered for these applications.
