Subject: ARMv7: Alias dmbld() to dmb()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e43422b734269d23f336e5ca3c05dedd8fd52901;p=project%2Fbcm63xx%2Fatf.git

ARMv7: Alias dmbld() to dmb()

'dmb ld' is not a recognized instruction for ARMv7. Since generic code
may use 'dmb ld', alias it to 'dmb' when building for ARMv7.
