Subject: hw/arm/smmuv3: Fix decoding of ID register range
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=97fb318d37be4d21125e89c96e4e92ea33beac51;p=qemu.git

hw/arm/smmuv3: Fix decoding of ID register range

The SMMUv3 ID registers cover an area 0x30 bytes in size
(12 registers, 4 bytes each). We were incorrectly decoding
only the first 0x20 bytes.
