Nova changes for v6.17
DMA:
- Merge topic/dma-features-2025-06-23 from alloc tree.
- Clarify wording and be consistent in 'coherent' nomenclature.
- Convert the read!() / write!() macros to return a Result.
- Add as_slice() / write() methods in CoherentAllocation.
- Fix doc-comment of dma_handle().
- Expose count() and size() in CoherentAllocation and add the
corresponding type invariants.
- Implement CoherentAllocation::dma_handle_with_offset().
nova-core:
- Various register!() macro improvements.
- Custom Sleep / Delay helpers (until the actual abstractions land).
- Add DMA object abstraction.
- VBIOS
- Image parser / iterator.
- PMU table look up in FWSEC.
- FWSEC ucode extraction.
- Register sysmem flush page.
- Falcon
- Generic falcon boot code and HAL (Ampere).
- GSP / SEC2 specific code.
- FWSEC-FRTS
- Compute layout of FRTS region (FbLayout and HAL).
- Load into GSP falcon and execute.
- Add Documentation for VBIOS layout, Devinit process, Fwsec operation
and layout, Falcon basics.
- Update and annotate TODO list.
- Add Alexandre Courbot as co-maintainer.
Rust:
- Make ETIMEDOUT error available.
- Add size constants up to SZ_2G.
