From: Wu Zhangjin <wuzhangjin@xxxxxxxxx> to enhance the maintainability and scalability of the source code, there is a need to divide the files to the smallest logic function unit. at the same time, the header files references are cleaned up, and some loongson2e* names are changed to loongson* for future source code sharing between loongson-2e and loongson-2f Signed-off-by: Wu Zhangjin <wuzhangjin@xxxxxxxxx> --- arch/mips/include/asm/mach-loongson/loongson.h | 4 + arch/mips/include/asm/mach-loongson/pci.h | 7 +- arch/mips/loongson/fuloong-2e/Makefile | 3 +- arch/mips/loongson/fuloong-2e/bonito-irq.c | 7 +-- arch/mips/loongson/fuloong-2e/cmdline.c | 77 ++++++++++++++++++ arch/mips/loongson/fuloong-2e/init.c | 40 +++++++++ arch/mips/loongson/fuloong-2e/irq.c | 5 +- arch/mips/loongson/fuloong-2e/mem.c | 18 ++++- arch/mips/loongson/fuloong-2e/misc.c | 13 +++ arch/mips/loongson/fuloong-2e/pci.c | 30 +++---- arch/mips/loongson/fuloong-2e/prom.c | 90 --------------------- arch/mips/loongson/fuloong-2e/setup.c | 103 ++++++++---------------- arch/mips/loongson/fuloong-2e/time.c | 27 ++++++ 13 files changed, 230 insertions(+), 194 deletions(-) create mode 100644 arch/mips/loongson/fuloong-2e/cmdline.c create mode 100644 arch/mips/loongson/fuloong-2e/init.c create mode 100644 arch/mips/loongson/fuloong-2e/misc.c delete mode 100644 arch/mips/loongson/fuloong-2e/prom.c create mode 100644 arch/mips/loongson/fuloong-2e/time.c diff --git a/arch/mips/include/asm/mach-loongson/loongson.h b/arch/mips/include/asm/mach-loongson/loongson.h index 26308b5..bce85a8 100644 --- a/arch/mips/include/asm/mach-loongson/loongson.h +++ b/arch/mips/include/asm/mach-loongson/loongson.h @@ -24,6 +24,10 @@ extern unsigned long memsize, highmemsize;
