[PATCH v1 0/4] aarch64: Add support for FEAT_TLBID feature

[Srinath Parvathaneni]

Hi,

TLBI Domains feature changes TLBI, TLBIP and PLBI
system instructions. For the TLBI/PLBI instruction
with optional register argument <Rt> == 0b1111,
with FEAT_TLBID enabled they are permitted to have
an Rt value which is not 0b11111 and this is allowed
for all the TLBI/PLBI instructions with a <type> of
ALLE1*, ALLE2*, VMALL*, VMALLS12* or VMALLWS2* and a
<shareability> of IS or OS.

For all TLBIP *E1IS*, TLBIP *E1OS*, TLBIP *E2IS* and
TLBIP *E2OS* instructions that are currently dependent
on FEAT_D128 (+d128), will also be available with
FEAT_TLBID (+tlbid).

TLBID introduces following system registers.

* tlbididr_el1 (RO)
* vtlbid0_el2
* vtlbid1_el2
* vtlbid2_el2
* vtlbid3_el2
* vtlbidos0_el2
* vtlbidos1_el2
* vtlbidos2_el2
* vtlbidos3_el2

This patch series adds support for FEAT_TLBID feature,
which is enabled by new +tlbid option.

Regression tested for aarch64-none-elf target and found no
regressions.

Ok for binutils-master?

Regards,
Srinath
