2007-10-11[MIPS] Add support for BCM47XX CPUs.Aurelien Jarno1-0/+2
Note that the BCM4710 does not support the wait instruction, this is not a mistake in the code. It originally comes from the OpenWrt patches.

2006-11-30[MIPS] Load modules to CKSEG0 if CONFIG_BUILD_ELF64=nAtsushi Nemoto1-0/+55
This is a patch to load 64-bit modules to CKSEG0 so that can be compiled with -msym32 option. This makes each module ~10% smaller. * introduce MODULE_START and MODULE_END * custom module_alloc() * PGD for modules * change XTLB refill handler synthesizer * enable -msym32 for modules again (revert ca78b1a5c6a6e70e052d3ea253828e49b5d07c8a) New XTLB refill handler looks like this: 80000080 dmfc0 k0,C0_BADVADDR 80000084 bltz k0,800000e4 # goto l_module_alloc 80000088 lui k1,0x8046 # %high(pgd_current) 8000008c ld k1,24600(k1) # %low(pgd_current) 80000090 dsrl k0,k0,0x1b # l_vmalloc_done: 80000094 andi k0,k0,0x1ff8 80000098 daddu k1,k1,k0 8000009c dmfc0 k0,C0_BADVADDR 800000a0 ld k1,0(k1) 800000a4 dsrl k0,k0,0x12 800000a8 andi k0,k0,0xff8 800000ac daddu k1,k1,k0 800000b0 dmfc0 k0,C0_XCONTEXT 800000b4 ld k1,0(k1) 800000b8 andi k0,k0,0xff0 800000bc daddu k1,k1,k0 800000c0 ld k0,0(k1) 800000c4 ld k1,8(k1) 800000c8 dsrl k0,k0,0x6 800000cc mtc0 k0,C0_ENTRYLO0 800000d0 dsrl k1,k1,0x6 800000d4 mtc0 k1,C0_ENTRYL01 800000d8 nop 800000dc tlbwr 800000e0 eret 800000e4 dsll k1,k0,0x2 # l_module_alloc: 800000e8 bgez k1,80000008 # goto l_vmalloc 800000ec lui k1,0xc000 800000f0 dsubu k0,k0,k1 800000f4 lui k1,0x8046 # %high(module_pg_dir) 800000f8 beq zero,zero,80000000 800000fc nop 80000000 beq zero,zero,80000090 # goto l_vmalloc_done 80000004 daddiu k1,k1,0x4000 80000008 dsll32 k1,k1,0x0 # l_vmalloc: 8000000c dsubu k0,k0,k1 80000010 beq zero,zero,80000090 # goto l_vmalloc_done 80000014 lui k1,0x8046 # %high(swapper_pg_dir) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-10-03Attack of "the the"s in archMatt LaPlante1-1/+1
The patch below corrects multiple occurances of "the the" typos across several files, both in source comments and KConfig files. There is no actual code changed, only text. Note this only affects the /arch directory, and I believe I could find many more elsewhere. :) Signed-off-by: Adrian Bunk <bunk@stusta.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
