[PATCH v2 0/12] drm/tyr: firmware loading and MCU boot support

[Deborah Brouwer <deborah.brouwer@collabora.com>]

This series adds firmware loading and MCU boot support to the Tyr DRM
driver. It includes:
- A parser for the Mali CSF firmware binary format
- A kernel-managed BO type (KernelBo) for internal driver allocations
- GPU virtual memory (VM) integration using drm_gpuvm
- An MMU module and a generic slot manager
- Shmem-backed GEM support for Tyr
- Loading firmware, VM activation, and MCU boot at probe()

Dependencies:
- [PATCH v7 0/7] Rust bindings for gem shmem + iosys_map
https://lore.kernel.org/rust-for-linux/20260206223431.693765-1-lyude@redhat.com/

- [PATCH v4 0/6] Rust GPUVM immediate mode
https://lore.kernel.org/rust-for-linux/20260130-gpuvm-rust-v4-0-8364d104ff40@google.com/

- [PATCH v5 0/4] Introduce DeviceContext
