X-Git-Url: http://git.openwrt.org/%22https:/collectd.org//%22http:/www.crowdsec.net/%22/%22https:/collectd.org/%22http:/www.crowdsec.net/%22?a=commitdiff_plain;h=1ffaaec9ec409c4ab57baeda7772f2f3e2ccf4be;p=project%2Fbcm63xx%2Fatf.git

spd: trusty: pass max affinity level to Trusty

During System Suspend, the entire system loses its state. To allow Trusty
to save/restore its context and allow its TAs to participate in the suspend
process, it needs to look at the max affinity level being suspended. This
patch passes the max affinity level to Trusty to enable to do so.
