Enable the Corstone‑1000 Cortex‑A320 variant by: - Introduce `machine/include/corstone1000-a320.inc` to configure the default Ethos‑U MAC count when `cortexa320` is in MACHINE_FEATURES, and allow override via `ETHOSU_NUM_MACS`. - Add a KAS profile at `kas/corstone1000-a320.yml` for Cortex‑A320 FVP-based builds. - Extend corstone1000.inc to detect MACHINE_FEATURES (cortexa320) and pull in the matching tune-<core>.inc (default still Cortex-A35). - Add the `meta-ethos` layer as a dependency of `meta-arm-bsp` for Cortex‑A320 builds and define a new KMachine override to pull in the Ethos‑U driver recipe. - In `conf/machine/corstone1000-fvp.conf`, inspect `MACHINE_FEATURES` and set `FVP_EXE` to `FVP_Corstone-1000_with_Cortex-A320` when `cortexa320` is enabled, otherwise fall back to `FVP_Corstone-1000`. - In `recipes-devtools/fvp/fvp-corstone1000.bb`, add a `SRC_URI:cortexa320` entry (with checksums) for the Cortex‑A320 FVP build archive. - Disable the rootfs CPIO file compression so it is not compressed twice when bundled with the kernel Signed-off-by: Michael Safwat <michael.safwat@arm.com> Signed-off-by: Frazer Carsley <frazer.carsley@arm.com> Signed-off-by: Hugues KAMBA MPIANA <hugues.kambampiana@arm.com> Signed-off-by: Jon Mason <jon.mason@arm.com>
