Subject: [PATCH 0/7] powerpc: build / linker improvements
Date: Thu, 15 Sep 2022 01:47:39 +1000 [thread overview]
Message-ID: <20220914154746.1122482-1-npiggin@gmail.com> (raw)
This series is mainly about moving more things out of writable and
executable memory, and slightly moving the linker script in the
direction of the binutils ld internal linker script as we do.
Thanks,
Nick
