New Revision: 349327
URL: https://svnweb.freebsd.org/changeset/base/349327
Log:
Build an armv7 LINT kernel in addition to armv5 LINT. You might think this
had been done years ago. I did. All this time we've only compiled a LINT
kernel for TARGET_ARCH=arm. Now separate LINT-V5 and LINT-V7 configs are
generated and built.
There are two new files in arm/conf, NOTES.armv5 and NOTES.armv7, containing
some of what used to be in the arm NOTES file. That file now contains only
the bits that are common to v5 and v7.
The makeLINT.mk file now creates the LINT-V5 and LINT-V7 files by concatening
sys/conf/NOTES, arm/conf/NOTES, and arm/conf/NOTES.armv{5,7} in that order.
Added:
head/sys/arm/conf/NOTES.armv5 (contents, props changed)
