Subject: powerpc/eeh: Output PHB diag-data
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2c77e95741e1202f993a4126f1f401459f1bcd4d;p=openwrt%2Fstaging%2Fblogic.git

powerpc/eeh: Output PHB diag-data

When hitting frozen PE or fenced PHB, it's always indicative to
have dumped PHB diag-data for further analysis and diagnosis.
However, we never dump that for the cases. The patch intends to
dump PHB diag-data at the backend of eeh_ops::get_log() for PowerNV
platform.
