- add new SoCs support : exynos3250, 5260, 5410 and 5800 - enable multi-platform on exynos : consolidate exynos related Kconfig entries Note that this requires tags/samsung-cleanup and tags/samsung-clk-2 because of mostly migration exynos specific macros into mach-exynos and exynos related Kconfig entries. One more merge conflict happens in arch/arm/Kconfig for ARCH_EXYNOS due to SRAM stuff, even though tried to sort them out. Since just resolving it would be better I think, please remove ARCH_EXYNOS in arch/arm/Kconfig when merge conflict happens. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJTiNnJAAoJEA0Cl+kVi2xqw4AP/1h2Rtg5/VXTwspQNicVqmjy xh1R5HNkCK9J+Vs+hrajFog4lneTuKDimgJqwM4JcMR9Y6KFCVivMZ+rPpaVpa2o Ly50EgEUAx7iir/PswttUVsSAoP/LXwwP44tWgV6qwV4N2qZ4BPKSAkc+l4icrqv Zzx4h1sxMKF2oTarDsrBIj7UszZtIB6Dt00ogyEJ2BNgWcWzU51YtWOz6MdC+Eha Wz2cfnrl2GiSIUC+Y0jRxeNfJyIgVMvrWpC23d5QSO0qx5xDNhSq/+eNXpd4gTGc aMoBnTgzvymOgLYFkcDCDYxsehXqX1b3hHzu1BfRTWjcA9wmxFhC8eOiMAgDso79 V8L/k5/XVAP34TFzZR1ZD5rCqgBIuDgmeOqyzMAxMLVKTQZrJ/6smKq94FCCD89G lOtiLmAPems8g7DE2wpWsYiml7TyUHNqgHP4FWJThnERjBa+rDKsyozzgFLJLqD7 /qL+qn6C0COtfDN0SBiIiLyV/0j+DI+tS5uGWgKWxGkRLQev1GyWGsGJZBx1tlJB v0/aAEAFkTWg9b+dO9OdUXzbGvc3VAQbaiwfCb73vsEibuO3IGpsXsl0d+ChXUkK XbQW5nNHOCKJj1auAg+4AqWm+evSzjZa/gViUlxE0vpK1Bc8uXZy0sYhQwC0lBaB KBqHE3ImvgIgPhXa3t5R =/Vpg -----END PGP SIGNATURE----- Merge tag 'samsung-exynos' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/soc Samsung Exynos updates for 3.16 - add new SoCs support : exynos3250, 5260, 5410 and 5800 - enable multi-platform on exynos : consolidate exynos related Kconfig entries * tag 'samsung-exynos' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: (22 commits) ARM: EXYNOS: Enable multi-platform build support ARM: EXYNOS: Consolidate Kconfig entries ARM: EXYNOS: Add support for EXYNOS5410 SoC ARM: EXYNOS: Support secondary CPU boot of Exynos3250 ARM: EXYNOS: Add Exynos3250 SoC ID ARM: EXYNOS: Add 5800 SoC support ARM: EXYNOS: initial board support for exynos5260 SoC cpufreq: exynos: Fix the compile error ARM: S3C24XX: move debug-macro.S into the common space ARM: S3C24XX: use generic DEBUG_UART_PHY/_VIRT in debug macro ARM: S3C24XX: trim down debug uart handling ARM: compressed/head.S: remove s3c24xx special case ARM: EXYNOS: Remove unnecessary inclusion of cpu.h ARM: EXYNOS: Migrate Exynos specific macros from plat to mach ARM: EXYNOS: Remove exynos_subsys registration ARM: EXYNOS: Remove duplicate lines in Makefile ARM: EXYNOS: use v7_exit_coherency_flush macro for cache disabling ARM: dts: Remove g2d_pd node for exynos5420 ARM: dts: Remove mau_pd node for exynos5420 ARM: exynos_defconfig: enable HS-I2C to fix for mmc partition mount ...
