Linux2.6.28到Linux2.6.32的内核移植
今天从GIT上拖下最新的Android Linux2.6.32内核，对S3C6410的支持还是基本功能。 目前三星内核树上功能比较全的内核应该是28了，升级到32试试，本来以为只要换几个目录即可，没想到做下来发现还是要改很多东西。
过程如下：
1 替换目录 mach-s3c6400 mach-s3c6410 plat-s3c plat-s3c64XX plat-s3C24XX(不确定这个是否一定要换)
2 修改arch/arm/Kconfig
config HZ int default 128 if ARCH_L7200 default 200 if ARCH_EBSA110 || ARCH_S3C2410 || ARCH_S3C64XX || ARCH_S5P64XX || ARCH_S5PC1XX default OMAP_32K_TIMER_HZ if ARCH_OMAP && OMAP_32K_TIMER default AT91_TIMER_HZ if ARCH_AT91 default 100
config ARCH_S3C64XX bool "Samsung S3C64XX" select GENERIC_GPIO select HAVE_CLK help Samsung S3C64XX series based systems
3 修改arch/arm/mm/kconfig
# ARMv6 config CPU_V6 bool "Support ARM V6 processor" depends on ARCH_INTEGRATOR || MACH_REALVIEW_EB || ARCH_OMAP2 || ARCH_MX3 || ARCH_MSM || MACH_REALVIEW_PB11MP || MACH_REALVIEW_PB1176 || ARCH_S3C64XX || ARCH_S5P64XX default y if ARCH_MX3 default y if ARCH_MSM default y if (ARCH_S3C64XX || ARCH_S5P64XX) select CPU_32v6 select CPU_ABRT_EV6 select CPU_PABRT_NOIFAR select CPU_CACHE_V6 select CPU_CACHE_VIPT select CPU_CP15_MMU select CPU_HAS_ASID if MMU select CPU_COPY_V6 if MMU select CPU_TLB_V6 if MMU
4 以下是编译错误
arch/arm/kernel/process.c: In function 'arm_machine_restart': arch/arm/kernel/process.c:103: error: too many arguments to function 'arch_reset' make[1]: *** [arch/arm/kernel/process.o] 错误 1
解决方法：arch/arm/kernel/process.c //arch_reset(mode, cmd); arch_reset(mode);

5 至此总算内核可以运行，怕DMA那有问题，导致下一步添加驱动出现问题，god包邮吧
