powerpc/Makefile: Remove bits related to the previous use of -mcmodel=large

2024-05-07T13:48:45+00:00

All supported compilers today (gcc v5.1+ and clang v11+) have support for -mcmodel=medium. As such, NO_MINIMAL_TOC is no longer being set. Remove NO_MINIMAL_TOC as well as the fallback to -mminimal-toc.

powerpc/85xx: Remove FSL_85XX_CACHE_SRAM

2022-05-22T05:58:30+00:00

CONFIG_FSL_85XX_CACHE_SRAM is an option that is not user selectable and which is not selected by any driver nor any defconfig. Remove it and all associated code.

powerpc: Remove Xilinx PPC405/PPC440 support

2020-05-28T13:24:34+00:00

The latest Xilinx design tools called ISE and EDK has been released in October 2013. New tool doesn't support any PPC405/PPC440 new designs. These platforms are no longer supported and tested. PowerPC 405/440 port is orphan from 2013 by commit cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and commit 19624236cce1 ("MAINTAINERS: Update Grant's email address and maintainership") that's why it is time to remove the support fot these platforms.

powerpc/sysdev: drop simple gpio

2019-11-21T04:41:34+00:00

There is a config item CONFIG_SIMPLE_GPIO which provides simple memory mapped GPIOs specific to powerpc. However, the only platform which selects this option is mpc5200, and this platform doesn't use it. There are three boards calling simple_gpiochip_init(), but as they don't select CONFIG_SIMPLE_GPIO, this is just a nop. Simple_gpio is just redundant with the generic MMIO GPIO driver which can be found in driver/gpio/ and selected via CONFIG_GPIO_GENERIC_PLATFORM, so drop simple_gpio driver.

powerpc/powernv: Move SCOM access code into powernv platform

2019-08-05T08:53:03+00:00

The powernv platform is the only one that directly accesses SCOMs. Move the support code to platforms/powernv, and get rid of the PPC_SCOM Kconfig option, as SCOM support is always selected when compiling for powernv. This also means that the Kconfig item for CONFIG_SCOM_DEBUGFS will show up in menuconfig in the platform menu, rather than at the root, which is a much better location.

powerpc: change CONFIG_6xx to CONFIG_PPC_BOOK3S_32

2018-11-26T11:33:37+00:00

Today we have: config PPC_BOOK3S_32 bool "512x/52xx/6xx/7xx/74xx/82xx/83xx/86xx" [depends on PPC32 within a choice] config PPC_BOOK3S def_bool y depends on PPC_BOOK3S_32 || PPC_BOOK3S_64 config 6xx def_bool y depends on PPC32 && PPC_BOOK3S 6xx is therefore redundant with PPC_BOOK3S_32. In order to make the code clearer, lets use preferably PPC_BOOK3S_32. This will allow to remove CONFIG_6xx in a later patch. Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman

powerpc: Add -Werror at arch/powerpc level

2018-10-18T13:56:17+00:00

Back when I added -Werror in commit ba55bd74360e ("powerpc: Add configurable -Werror for arch/powerpc") I did it by adding it to most of the arch Makefiles. At the time we excluded math-emu, because apparently it didn't build cleanly. But that seems to have been fixed somewhere in the interim. So move the -Werror addition to the top-level of the arch, this saves us from repeating it in every Makefile and means we won't forget to add it to any new sub-dirs. Signed-off-by: Michael Ellerman

powerpc/Makefiles: Convert ifeq to ifdef where possible

2018-08-07T14:32:36+00:00

In Makefiles if we're testing a CONFIG_FOO symbol for equality with 'y' we can instead just use ifdef. The latter reads easily, so convert to it where possible. Signed-off-by: Rodrigo R. Galvao Reviewed-by: Mauro S. M. Rodrigues Signed-off-by: Michael Ellerman
