Subject: powerpc/85xx: Add QE common init function
X-Git-Tag: firefly_0821_release~176^2~4556^2~5^2~34
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=72c916ae97ff503b01fa21efe91d4328439ab004;p=firefly-linux-kernel-4.4.55.git

powerpc/85xx: Add QE common init function

Define a QE init function in common file, and avoid
the same codes being duplicated in board files.
