Add a decoupled toolchain-only defconfig and a toolchain.yml matrix entry that publish toolchain.hisilicon-hi3519dv500 (aarch64-openipc-linux-musl, musl + C++, gcc 13, 5.10 kernel headers). `make toolchain` runs `make sdk`, which builds world; the decoupled config builds only the cross toolchain + busybox so the SDK can be packaged without the full firmware. The config has no kernel, so BR2_KERNEL_HEADERS is pinned to 5.10 (it would otherwise fall back to buildroot's newest-series default).
The BROKEN_MMAP=1 define forces a raw syscall(SYS_mmap2) path (patch 0002) needed by 32-bit musl. SYS_mmap2 is 32-bit-ARM-only — aarch64 has SYS_mmap and its musl mmap() works fine — so only apply it on 32-bit targets.
The aarch64 Cortex-A55 (V5/HISI_OT) counterpart of hi3516cv6xx, as one hi3519dv500 image with hi3516dv500 as an alias: - hi3519dv500_ultimate_defconfig: aarch64 musl, linux 5.10 (openipc/linux branch hisilicon-hi3519dv500), arm64 Image + FIT, squashfs. - board/hi3519dv500: kernel config, fit-image.its (DDR 0x40000000, arm64 0x80000 text offset), post-image.sh, plus the repack wiring in Makefile. - hisilicon-osdrv-hi3519dv500: load script + vendor MPP userspace .so from the Hi3519DV500 SDK V1.0.1.1. Boots to a shell on the qemu-hisilicon hi3519dv500 machine (SMP + Ethernet). majestic, divinus and hisilicon-opensdk have no aarch64 DV500 build yet and are left off; source-built sensors will come from openhisilicon.

majestic,divinus,hisilicon-opensdk— no aarch64 DV500 build yet, left off.OpenIPC/openhisilicon.Kept out of the CI build matrix.
