Introduce LoongArch64 at architecture level. Config.in.loongarch is prepared for possible loongarch32 enablement in future, thus BR2_ARCH_IS_64 is being depended by some 64bit only options. Internal toolchain is supported, as our minimal binutils version is already beyond LoongArch minimal version and GCC option is limited by BR2_ARCH_NEEDS_GCC_AT_LEAST_12. BR2_ARCH_HAS_NO_TOOLCHAIN_BUILDROOT is selected temporary and it's going to be rmoved after we gain libc support.

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.
