This is done for sun7i only since I don't have access to any other sunxi platforms with sata included. The PHY setup is derived from the Alwinner releases and Linux, but is mostly undocumented. The Allwinner AHCI controller also requires some magic (and, again, undocumented) DMA initialisation when starting a port. This is added under a suitable ifdef. This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on contents of Linux DTS files, including SATA power pin config taken from the DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

This patch limits itself to the nios2 architecture. The problem is that for the size_t (%zu, %zd, ...) arguments of printf GCC does not verify the type match to size_t type. It verifies the type match to the compiler-defined __SIZE_TYPE__ type. Thus, if size_t is defined different from __SIZE_TYPE__ - warnings inevitably appear. There is a comment by Thomas Chou to the (rejected) patch: http://patchwork.ozlabs.org/patch/272102/ which explains that the older GCC toolchains (gcc-3.4.6 and gcc-4.1.2) expect size_t to be "unsigned long" and the newer expect it to be "unsigned int". Thus, no matter how we define size_t - either way warnings appear when using some GCC version. By rejecting that patch, a choice was made to prefer older GCC versions and leave the warnings when building with the newer toolchains. Personally, I disagree with this choice... In any case, this patch proposes a way to fix the warnings for any GCC version. Just define size_t using the __SIZE_TYPE__ compiler-defined type and the type verification will pass. I tested that this fixes the warning on GCC 4.8.3. I don't have an older toolchain to test with, but __SIZE_TYPE__ was definitely defined in GCC 3.4.6, so it should work there too.
