2009-09-17MIPS: Loongson: Change naming methodsWu Zhangjin12-573/+0
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.

2009-09-17MIPS: Loongson: Add oprofile supportWu Zhangjin1-0/+2
This kernel support is needed by the user-space tool:oprofile to profile linux kernel or applications via loongson2 performance counters. you can enable this driver via CONFIG_OPROFILE = y or m. On Loongson2 there are two performance counters, each one can count 16 events respectively. when anyone of the performance counter overflows, an interrupt will be generated and is routed to the IRQ MIPS_CPU_IRQ_BASE + 6.

2009-09-17MIPS: Loongson: PCI: Clean up pcimap setupWu Zhangjin1-15/+26
Fixup the wrong original comment of pcimap, and make the source code more understandable. and also, some new extra consideration is added in. Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: clean up the coding styleWu Zhangjin11-173/+21
With the help of script/checkpatch.pl, i have cleaned up the coding style. 1. remove un-needed header files and tune some comments. 2. remove some un-needed { } add a new header file loongson.h: 3. move some common header files to loongson.h 4. move some common extern declartions to loongson.h and this new header file is needed for future loongson2f support.

2009-09-17MIPS: Loongson: Split the implementation of prom and setup partsWu Zhangjin8-85/+168
This patch split the old initilization and setup implementation to several file, one file one logic function. the other main changes include: 1. as the script/checkpatch.pl suggests, use strict_strtol instead of simple_strtol in arch/mips/lemote/lm2e/cmdline.c 2. use the existed macros in asm/mips-boards/bonito64.h as the arguments of set_io_port_base() and remove the un-needed ones in asm/mach-lemote/pci.h Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: PCI: use existing mips_io_port_baseWu Zhangjin1-4/+1
mips_io_port_base is initialized via set_io_port_base() in arch/mips/lemote/lm2e/setup.c, we can use it directly here. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: pm: clean up the reboot supportWu Zhangjin1-8/+10
Several magic numbers have been replaced by relative macros, which will be more readable and understandable. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: pm: Remove redundant source codeWu Zhangjin1-6/+1
The implmentation of loongson2e_power_off and loongson2e_halt is almostly the same, just preserve one of them. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Add new early_printk implmentationWu Zhangjin2-0/+46
This patch is based on the implementation in the lm2e-fixes branch of Philippe's git://git.linux-cisco.org/linux-mips.git and the malta-specific early_printk implementation. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Remove out-of-date board-specific kgdb source codeWu Zhangjin2-147/+1
Since the re-implementation of kgdb by commit 8854700115ecf8aa6f087aa915b7b6cf18090d39 the platform-specific version has become superfluous, remove it. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Remove existing early_printk implementationWu Zhangjin1-6/+0
Removes the existing implementation of early_printk for fulong. The old implementation was based on the outdated board-specific dbg_io.c. Since commit 8d60a903d986ffa26c41f0092320a3b9da20bfaf dbg_io.c is not longer needed; it will be removed by the next patch, and a new implementation of early_printk will be added later.
