* More foolproofing of the CPU configuration.Ralf Baechle2005-10-291-2/+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>
* pci-expmem-hackAndrew Isaacson2005-10-291-0/+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).

* Fix zero length sys_cacheflushAtsushi Nemoto2005-10-291-0/+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>

| | | | | | | | | 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.
