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
