	Currently, the exception handling code on ARM turns on alignment checks as an easy way to generate an exception for testing purposes. It was leaving it on which disabled unaligned accesses for other, unlreated code running later. This change adjusts the code so the original value of the alignment bit is restored after the test exception.

2013-03-08	ARMV7 and Google/Snow: Add exception support code to the ramstage	Ronald G. Minnich
	This is previously used exception code from libpayload. On startup it installs and then tests an exception handler. The test is an unaligned memory operation. Yes, we've seen what might be exceptions in the ramstage, and it makes sense to handle them. This code is identical in structure and operation to the previously committed payload exception handler, though we reserve the right to change it as circumstances require. The remaining question is whether we need it in romstage. Change-Id: I24484686c33c9757af8ba171ebae9773828fb69d Signed-off-by: Gabe Black <gabeblack@google.com> Signed-off-by: Ronald G.
