[U-Boot] [PATCH][v2] ARMv8:ls2-2080a: Implement core ERRATA 829520, 833471

2016-01-27 Thread Ashish Kumar
* 829520: Code bounded by indirect conditional branch might corrupt instruction stream, Workaround: Set CPUACTLR_EL1[4] = 1'b1 to disable the Indirect Predictor * 833471: VMSR FPSCR functional failure or deadlock Workaround: Set CPUACTLR[38] to 1, which forces FPSCR write flush Signed-
