Subject: Add feature reference in .dat files
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ad7fc756d12a841d4b8dd707568426d875e26755;p=binutils-gdb.git

Add feature reference in .dat files

For all targets which use the newer style target descriptions, add a
"feature" marker in the dat files.
Update regdat.sh to parse feature, but do not use it (yet).

	target descriptions.
