2005-10-29Hack to resolve longstanding prefetch issueRalf Baechle1-0/+15
Prefetching may be fatal on some systems if we're prefetching beyond the end of memory on some systems. It's also a seriously bad idea on non dma-coherent systems. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29More foolproofing of the CPU configuration.Ralf Baechle1-2/+149
Limit the number of cpu type options in the cpu menu to just those types that are actually available for the select platform. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29pci-expmem-hackAndrew Isaacson1-0/+8
CFE 1.2.5 and earlier fails to turn on the ExpMemEn bit in the PCIFeatureControl register, which means that DMA does not work beyond physical address 01_0000_0000, ergo to DRAM beyond 1GB. With ExpMemEn turned on, 01_0000_0000-0f_ffff_ffff is mapped, so DMA works for up to 61 GB of DRAM. Will be fixed in CFE 1.2.6 (yet to be released).

2005-10-29Fix zero length sys_cacheflushAtsushi Nemoto1-0/+2
Cacheflush(0, 0, 0) was crashing the system. This is because flush_icache_range(start, end) tries to flushing whole address space (0 - ~0UL) if both start and end are zero. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Convert kgdb_cpulock into a raw_spinlock_t. SPIN_LOCK_UNLOCKED is deprecated and it's replacement DEFINE_SPINLOCK is not suitable for arrays of spinlocks. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Make kgdb_wait static.Ralf Baechle1-1/+1
Nothing outside gdb-stub.c uses kgdb_wait, so change it's definition to static. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2005-10-29Don't copy SB1 cache error handler to uncached memory.Ralf Baechle1-1/+0
This may have made sense on a paranoid day with pass 1 BCM1250 processors that were throwing cache error exception left and right for no good reason. On modern silicion that hardly makes sense and the code had gotten just an obscurity ... Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2005-10-29Sync c-tx39.c with c-r4k.c.Atsushi Nemoto1-4/+5
tx39_flush_cache_range() does nothing if !cpu_has_dc_aliases. It should flush d-cache and invalidate i-cache since the TX39(H2) has separate I/D cache. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
