After conversion to using device tree only (no board files) on mach-exynos using exynos4_defconfig results in unbootable kernel (I used next-20130626): --- Uncompressing Linux... done, booting the kernel. Booting Linux on physical CPU 0x900 Linux version 3.10.0-rc7-next-20130626-dirty (bzolnier@amdc1032) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) 3 CPU: ARMv7 Processor [412fc091] revision 1 (ARMv7), cr=10c5387d CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache Error: unrecognized/unsupported machine ID (r1 = 0x00000bad).

Available machine support: ID (hex) NAME Available machine support: ID (hex) NAME ffffffff Samsung Exynos4 (Flattened Device Tree) ffffffff Samsung Exynos4 (Flattened Device Tree) Please check your kernel config and/or bootloader. --- There is no much point in trying to fix exynos4_defconfig because exynos_defconfig also works for EXYNOS4 SoCs, is being kept up to date (for the comparison the last exynos4_defconfig update was in November 2011) and has more useful stuff enabled (i.e. exynos4_defconfig doesn't even have EXT3 or EXT4 enabled, it only has EXT2 turned on). Another advantage of using one defconfig for both EXYNOS4 and EXYNOS5 is that it makes development and testing easier. It should allow us to catch early EXYNOS4 regressions caused by EXYNOS5 changes and also EXYNOS4 changes that break EXYNOS5.
