Subject: [POWERPC] bootwrapper: Factor out dt_set_mac_address()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=27ff35d9026b5d41d66ed95b65d7819db4cf5fb1;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[POWERPC] bootwrapper: Factor out dt_set_mac_address()

This allows callers to set addresses one at a time when that would be more
convenient.
