Subject[PATCH 2/4] arm64: arm_arch_timer: remove fsl-a008585 parameter
Date
From: Ding Tianhong <dingtianhong@huawei.com>

Having a command line option to flip the errata handling for a
particular erratum is a little bit unusual, and it's vastly superior to
pass this in the DT. By common consensus, it's best to kill off the
command line parameter.
