MIPS: Add -Werror to arch/mips/Kbuild Adding subdirs-ccflags-y := -Werror to arch/mips/Kbuild let us in one go cover all files with -Werror. In addition this allows us to remove the individual -Werror definition in various Makefile. Adding the definition to Kbuild as a recursive option help us not to forget to do so. With this change we now compile arch/mips/kernel/cpufreq with -Werror One drawback: When specifying a subdirectory covered by the Kbuild file like this: make arch/mips/kernel/ then kbuild fails to pick up the -Werror definition.

MIPS: Introduce support for Platform definitions Move platform specific definitions to the platfrom directories. Each platform shall do the following: 1) include an entry in arch/mips/Kbuild.platforms 2) add relevant definitions to arch/mips/<platform>/Platform This commits changes ar7 to the new scheme as an example. Introducing a platform speecific Platfrom file has following advantages: 1) decentralization of platfrom definitions 2) simplification af arch/mips/Makefile 3) force all platfrom to build with -Werror (done in arch/mips/Kbuild) [Ralf: Remove forgotten -Werror from AR7 Makefile] Signed-off-by: Sam Ravnborg <sam@ravnborg.org> To: linux-mips <linux-mips@linux-mips.org> To: Wu Zhangjin <wuzhangjin@gmail.com> Patchwork: https://patchwork.linux-mips.org/patch/1302/ Patchwork: http://patchwork.linux-mips.org/patch/1308/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 2010-05-30 14:27:10 +00:00			`# platform specific definitions`

MIPS: Repair Kbuild make clean breakage. When running make clean, Kbuild doesn't process the .config file, so nothing generates a platform-y variable. We can get it to descend into the platform directories by setting $(obj-). The dec Platform file was unconditionally setting platform-, obliterating its previous contents and preventing some directories from being cleaned. This is change to an append operation '+=' to allow cavium-octeon to be cleaned.
