2020-09-07MIPS: Remove mach-*/war.hThomas Bogendoerfer
After conversion of all WAR defines we can now remove all mach-*/war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Get rid of BCM1250_M3_WARThomas Bogendoerfer
BCM1250_M3_WAR is depending on CONFIG_CONFIG_SB1_PASS_2_WORKAROUNDS. So using this option directly lets and remove define. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Replace SIBYTE_1956_WAR by CONFIG_SB1_PASS_2_WORKAROUNDSThomas Bogendoerfer
SB1250 uart bug is related to PASS 2 workarounds. Use config CONFIG_SB1_PASS_2_WORKAROUNDS directly and get rid of SIBYTE_1956_WAR. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Convert MIPS34K_MISSED_ITLB_WAR into a config optionThomas Bogendoerfer
Use a new config option to enable MIPS 34K ITLB workaround and remove define from different war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Convert R10000_LLSC_WAR info a config optionThomas Bogendoerfer
Use a new config option to enabel R1000_LLSC workaound and remove define from different war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Convert ICACHE_REFILLS_WORKAROUND_WAR into a config optionThomas Bogendoerfer
Use a new config option to enable I-cache refill workaround and remove define from different war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Convert TX49XX_ICACHE_INDEX_INV into a config optionThomas Bogendoerfer
Use a new config option to enable TX49XX I-cache index invalidate workaround and remove define from different war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Remove MIPS4K_ICACHE_REFILL_WAR and MIPS_CACHE_SYNC_WARThomas Bogendoerfer
Neither MIPS4K_ICACHE_REFILL_WAR nor MIPS_CACHE_SYNC_WAR are implemented, so removing defines for it won't change anything. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Convert R4600_V2_HIT_CACHEOP into a config optionThomas Bogendoerfer
Use a new config option to enable R4600 V2 cacheop hit workaround and remove define from different war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Convert R4600_V1_HIT_CACHEOP into a config optionThomas Bogendoerfer
Use a new config option to enable R4600 V1 cacheop hit workaround and remove define from the different war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2020-09-07MIPS: Convert R4600_V1_INDEX_ICACHEOP into a config optionThomas Bogendoerfer
Use a new config option to enable R4600 V1 index I-cacheop workaround and remove define from different war.h files. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2019-07-23MIPS: Remove unused R5432_CP0_INTERRUPT_WARPaul Burton
R5432_CP0_INTERRUPT_WAR is defined as 0 for every system we support, and so the workaround is never used. Remove the dead code. Signed-off-by: Paul Burton <paul.burton@mips.com> Cc: linux-mips@vger.kernel.org
2017-07-11MIPS16e2: Provide feature overrides for non-MIPS16 systemsMaciej W. Rozycki
Hardcode the absence of the MIPS16e2 ASE for all the systems that do so for the MIPS16 ASE already, providing for code to be optimized away. Signed-off-by: Maciej W. Rozycki <macro@imgtec.com> Reviewed-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/16097/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2015-07-14MIPS: SB1: Remove support for Pass 1 parts.Ralf Baechle
Pass 1 parts had a number of significant erratas and were only available in small numbers and under NDA. Full support also required the use of a special toolchain that kept branches properly aligned. These workarounds were never upstreamed and the only toolchain known to have them is Montavista's GCC 3.0-based toolchain which completly obsoleted if not useless these days. So now that automated testing has tripped over the user of the -msb1-pass1-workarounds option, rather than fixing it remove support for pass 1 parts. Probably nobody will notice. I seem to own the last know pass 1 board and I haven't noticed another one in the wild in the past decade, at least. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2013-02-01MIPS: Whitespace cleanup.Ralf Baechle
Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-12-13MIPS: PMC-Sierra Yosemite: Remove support.Ralf Baechle
Nobody seems to be interested anymore and upstream also never had an ethernet driver. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-10-11MIPS: Hardwire detection of DSP ASE Rev 2 for systems, as required.Ralf Baechle
Most supported systems currently hardwire cpu_has_dsp to 0, so we also can disable support for cpu_has_dsp2 resulting in a slightly smaller kernel. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2010-04-12MIPS: Sibyte: Apply M3 workaround only on affected chip types and versions.Ralf Baechle
Previously it was unconditionally used on all Sibyte family SOCs. The M3 bug has to be handled in the TLB exception handler which is extremly performance sensitive, so this modification is expected to deliver around 2-3% performance improvment. This is important as required changes to the M3 workaround will make it more costly. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
