Since the LoongArch64 introduction in commit [1], the Kconfig menus
allows selecting lsx and lasx SIMD options independently of the FPU
configuration.
When lsx or lasx SIMD is selected and FPU is "none", host-gcc-initial
is failing at configuration time, with error:
--with-simd=lasx conflicts with --with-fpu=none
According to the gcc configuration script [2], lsx and lasx values
are valid only if FPU is 64.
This commit adds the missing "depends on BR2_LOONGARCH_FPU_64" for
BR2_LOONGARCH_SIMD_LSX and BR2_LOONGARCH_SIMD_LASX options.

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
