[U-Boot] [PATCH v3] armv8: errata: Implement workaround for Cortex-A53 Erratum 855873

2017-12-27 Thread Alison Wang
855873: An eviction might overtake a cache clean operation Workaround: The erratum can be avoided by upgrading cache clean by address operations to cache clean and invalidate operations. For Cortex-A53 r0p3 and later release, this can be achieved by setting CPUACTLR.ENDCCASCI to 1. This patch is
