* ARM: Allow to mask data abortsSascha Hauer2015-02-271-0/+37
Sometimes it's useful to test if a memory operation works or aborts. This adds data_abort_mask() to ignore data aborts and data_abort_unmask() to enable them again. This is used in the next step for the 'md' command so that illegal addresses just show 'xxxxxxxx' instead of crashing the system. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
