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

-# eventually, these chanegs can be merged into linux-libre
+# This PKGBUILD includes a lot of cruft, to minimize the diff.
+# 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.
+#
+# The makedepends_x86_64, source_x86_64, and sha512sums_x86_64 arrays
+# (also source_aarch64 and sha512sums_aarch64 obviously),
+# and any lines with comment: '# aarch64 over-ride'
+# 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).
