2010-02-22resource/PCI: align functions now return start of resourceDominik Brodowski1-2/+2
As suggested by Linus, align functions should return the start of a resource, not void. An update of "res->start" is no longer necessary.

2009-12-17MIPS: Lemote 2F: Add PCI supportWu Zhangjin3-1/+216
PCI support for the Fuloong 2E and Lemote Loongson 2F family machines is mostly identical with the exception of CS5536 support. Rename ops-fuloong2e.c to ops-loongson2.c then add the CS5536 support to share most of the source code among Loongson machines.

2009-12-17MIPS: Bonito64: Make Loongson independent from Bonito64 code.Wu Zhangjin4-10/+158
The built-in Loongson 2E/2F northbridge in is bonito64-compatible but not identical with it. To avoid influencing the original bonito64 support and make the loongson support more maintainable, it's better to separate the Bonito64 code from the Loongson code. This also prepares the kernel for the coming Loongson 2f machines family support.

2009-09-17MIPS: Loongson: Change naming methodsWu Zhangjin3-3/+3
To make source code of loongson sharable to the machines(such as gdium) made by the other companies, we rename arch/mips/lemote to arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to FULOONG2E to make it distinguishable to the future FULOONG2F. and also, some other relative tuning is needed.

Certain X11 servers such as the SIS server will only work if PCI mmap is implemented. This patch implements PCI mmap but to be on the same side so close to a release it only supports uncached mappings so performance will not be optimal for some uses such as framebuffers.
