Subject: target-tricore: introduce ISA v1.6.1 feature
X-Git-Tag: v2.4.0-rc0~123^2~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6d2afc8a5edc042e4e7c2ceb49f7cabe02aae793;p=thirdparty%2Fqemu.git

target-tricore: introduce ISA v1.6.1 feature

The aurix platform contains of several different cpu models and uses
the 1.6.1 ISA. This patch changes the generic aurix model to the more
specific tc27x cpu model and sets specific features.
