[ARM] nommu: confirms the CR_V bit in nommu mode
In nommu mode, the exception vector location depends on the platforms. Some of the implementations may have some special exception control forwarding method in their ROM/flash and for some of them has its own re-mapping mechanism by the h/w. This patch introduces a special configuration CONFIG_CPU_HIGH_VECTOR which turns on the CR_V bit in nommu mode. The CR_V bit is turned off by default. This feature depends on CP15 and does not supported by ARM740. Signed-off-by: NHyok S. Choi <hyok.choi@samsung.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
