The ARM multi-platform feature allows for having support for multiple ARM SoCs/platforms within a single Linux kernel image. Traditionally, the ARM Linux kernel situation has been a fragmented mess and needing separate kernel images for different Systems-on-a-Chip. With the Linux 3.7 kernel and this multi-platform support, it became possible to have one kernel for covering Calxeda Highbank, Versatile Express, Altera, PicoXcell, and other SoCs.
With the Linux 3.10 kernel, the ARM multi-platform support may now extend to cover the very popular Samsung Exynos family. Exynos SoCs are used from the Google Samsung Chromebook to the Google Nexus 10 to numerous other mobile devices.
Arnd Bergmann published a set of 30 patches on Wednesday to cover the ARM Exynos platform against the latest code. Bergmann writes at the beginning of his patch series, "It would be really nice to still get this merged for 3.10. A lot of the patches are really trivial, but there are some complex ones as well."
