Subject: [PATCH AUTOSEL 4.14 01/37] net: wan: wanxl: use allow to pass CROSS_COMPILE_M68k for rebuilding firmware
Date: Sat, 11 Apr 2020 19:12:50 -0400 [thread overview]
Message-ID: <20200411231327.26550-1-sashal@kernel.org> (raw)
From: Masahiro Yamada <masahiroy@kernel.org>
[ Upstream commit 63b903dfebdea92aa92ad337d8451a6fbfeabf9d ]
As far as I understood from the Kconfig help text, this build rule is
used to rebuild the driver firmware, which runs on an old m68k-based
chip. So, you need m68k tools for the firmware rebuild.
wanxl.c is a PCI driver, but CONFIG_M68K does not select CONFIG_HAVE_PCI.
So, you cannot enable CONFIG_WANXL_BUILD_FIRMWARE for ARCH=m68k. In other
words, ifeq ($(ARCH),m68k) is false here.
I am keeping the dead code for now, but rebuilding the firmware requires
'as68k' and 'ld68k', which I do not have in hand.
Instead, the kernel.org m68k GCC [1] successfully built it.
Allowing a user to pass in CROSS_COMPILE_M68K= is handier.

+ It requires m68k toolchains and hexdump programs.
You should never need this option, say N.
