This commit adds the Cortex-A710 core, which is an implementation of
the armv9.0a ISA. See: [1] [2].
This CPU support was added in GCC 12. See [3] [4].
Cortex-A710 support has been added in QEmu in commit [5], first
included in v8.2.0.
This CPU supports Aarch32 only in EL0 (user-space). This means it's
technically possible to compile Aarch32 code targeting. GCC has the
support to do so. Since Buildroot recompiles a full system (ATF,
Kernel, user-space) this support has limited value. This is why this
CPU is limited to 64bit builds only.

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.
