# Maintainers: Parabola hackers <dev@lists.parabola.nu>
-# WIP - Based on the linux-libre package.

-# Eventually, these chanegs can be merged into linux-libre
-# once parabola has an 'aarch64' build target and repos.
-
-# NOTE: aarch64 is not yet a valid parabola target.
-# This PKGBUILD is inteneded to be cross-compiled
-# only from an x86_64 librechroot. The x86_64 build of linux-libre
-# does not have any specail per-arch treatments; so that mechanism is
-# over-ridden for the special purpose of the cross-compilation.
+# WIP: This PKGBUILD is derived from the 'linux-libre' PKGBUILD,
+# and includes a lot of unused cruft, to minimize the diff.
+# Eventually, these differences can be merged into linux-libre,
+# once parabola has an 'aarch64' build target and repos.

-# indicate code that would eventually be deleted or associated with
-# $CARCH == aarch64, if/when that target exists.
-# All other LOCs of consequence in this file,
-# except for the `make` and `strip` commands,
-# should be identical to the linux-libre PKGBUILD.
-# In this way, the diff is minimal against the linux-libre PKGBUILD;
-# and it is obvious which parts should become aarch64-specific
-# (eg: source_x86_64 simpliy becomes source_aarch64).
+# For now, 'aarch64' is not yet a valid parabola target.

+# parabola armv7h systems. This PKGBUILD is intended to be cross-compiled
