Sync the Intel and AMD CPU target list with GCC 13. Multiple references are used for flags and synonyms [0] [1] [2] [3]. For Intel: Add Ivy Bridge, Sierra Forest, Grand Ridge, Knights Landing, Knights Mill, Granite Rapids, and Granite Rapids-D. The Sapphire Rapids CPU target supports Emerald Rapids. The Alder Lake CPU target supports Raptor Lake and Meteor Lake. Note: Knights Landing/Mills are based on Xeon Phi and do support some AVX512 extensions, but not the full subset required by BR2_X86_CPU_HAS_AVX512 For AMD: Add Bobcat, Bulldozer, Piledriver, Excavator, and Zen 1-4. Add a comment to BR2_X86_CPU_HAS_AVX512 to explain the expected extensions supported by the CPU. This flag was first selected by skylake-avx512 and encompasses what appears to be a standard subset across CPUs [3] and chapter 3 of the x86-64 psABI [4]: AVX512F, AVX512BW, AVX512CD, AVX512DQ, AVX512VL CPUs selecting this flag should, at a minimum, support this subset of AVX512 extensions.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
