Subject: broadcom/vc5: Move the TLB loads and stores to helper functions.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f13fe510d1d5d68b63f90ce63a7153220a25e138;p=mesa.git

broadcom/vc5: Move the TLB loads and stores to helper functions.

This is going to get more complicated with V3D 4.1 support, which redoes
all the TLB packets.
