Hi! matt,


What is KERNEL_EXT_BASE?  I think KERNEL_BASE_EXT correctly.

$ grep _EXT /sys/arch/evbarm/conf/std*
/sys/arch/evbarm/conf/std.adi_brh:options       KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.armadillo9:options    KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.g42xxeb:options       KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.gumstix:options       KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.imx31:options         KERNEL_BASE_EXT=0x80000000
/sys/arch/evbarm/conf/std.ixdp425:options       KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.ixm1200:options       KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.kuroboxarm:options    KERNEL_BASE_EXT=0xc0000000
/sys/arch/evbarm/conf/std.lubbock:options       KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.nslu2:options         KERNEL_BASE_EXT=0xc0000000
/sys/arch/evbarm/conf/std.tisdp24xx:options     KERNEL_BASE_EXT=0x80000000
/sys/arch/evbarm/conf/std.tsarm:options         KERNEL_EXT_BASE=0xc0000000
/sys/arch/evbarm/conf/std.viper:options         KERNEL_EXT_BASE=0xc0000000

$ grep -r KERNEL_EXT_BASE /sys/arch/evbarm/include/*            <-- nothing!!
$ grep -r KERNEL_BASE_EXT /sys/arch/evbarm/include/*
/sys/arch/evbarm/include/vmparam.h:#ifdef KERNEL_BASE_EXT
/sys/arch/evbarm/include/vmparam.h:#define      KERNEL_BASE

Add KERNEL_BASE_EXT=0xc0000000 to those plaforms that need it.
Note that armv6 and later systems will use 0x80000000 as the kernel start
so they can use the split TTBs in armv6 and later.
