ARM: SoC updates for 5.15 There are three noteworthy updates for 32-bit arm platforms this time: - The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based) SoCs. - The ixp4xx platform (based on Intel XScale) is finally converted to device tree, and all the old board files are getting removed now. - The Cirrus Logic EP93xx platform loses support for the old MaverickCrunch FPU. Support for compiling user space applications was already removed in gcc-4.9, and the kernel support for old applications could not be built with clang ias. After confirming that there are no remaining users, removing this from the kernel seemed better than adding support for unused features to clang. There are minor updates to the aspeed, omap and samsung platforms Signed-off-by: Arnd Bergmann <arnd@arndb.de>
