Julien Olivain de374e06d8 arch/arm: add the Cortex-A720 core
This commit adds the Cortex-A720 core, which is a armv9.2a ISA.
See: [1] [2].

This CPU support was added in GCC 14. See [3] [4].

Cortex-A720 processors are included in boards such as the
Radxa Orion O6. See [5].

This CPU supports Aarch64 only at all exception levels (EL0 to EL3).

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.
