Subject: ARM: 8648/2: nommu: display vectors base
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=58c16709f9cad7e6daabeaa5c94ac4dcb260aedd;p=openwrt%2Fstaging%2Fblogic.git

ARM: 8648/2: nommu: display vectors base

VECTORS_BASE displays the exception base address. Now on no-MMU as
the exception base address is dynamically estimated, define
VECTORS_BASE to the variable holding it.

As it is the case, limit VECTORS_BASE constant definition to MMU.
