[Qemu-arm] [PATCH 03/10] target/arm: Implement RAZ/WI HACTLR2 |
Date: |
Tue, 14 Aug 2018 13:42:47 +0100 |
The AArch32 HACTLR2 register maps to bits [63:32] of ACTLR_EL2.
We implement ACTLR_EL2 as RAZ/WI, so make HACTLR2 also RAZ/WI.
(We put the regdef next to ACTLR_EL2 as a reminder in case we
ever make ACTLR_EL2 something other than RAZ/WI).
