Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[ARM] 5015/1: arm: remove ARCH_CO285 Trying to compile a kerel for ARCH_CO285 fails with the following error: <-- snip --> ... CC arch/arm/mach-footbridge/dc21285.o /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/arm/mach-footbridge/dc21285.c: In function 'dc21285_base_address': /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/arm/mach-footbridge/dc21285.c:54: error: 'PCICFG0_BASE' undeclared (first use in this function) /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/arm/mach-footbridge/dc21285.c:54: error: (Each undeclared identifier is reported only once /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/arm/mach-footbridge/dc21285.c:54: error: for each function it appears in.) /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/arm/mach-footbridge/dc21285.c:57: error: 'PCICFG1_BASE' undeclared (first use in this function) /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/arm/mach-footbridge/dc21285.c: In function 'dc21285_scan_bus': /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/arm/mach-footbridge/dc21285.c:286: error: implicit declaration of function 'pci_scan_bus' ... make[2]: *** [arch/arm/mach-footbridge/dc21285.o] Error 1 <-- snip --> This does not seem to be a recent breakage. The ARCH_CO285 support is old - kernel 2.2.0 contains first traces of it, an it seems to have been pretty complete in later 2.2 kernels. Since it seems to be completely dead code now this patch therefore removes it. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
