2025-06-23	gpu: nova-core: update and annotate TODO list	Alexandre Courbot	1	-1/+1
	A few new dependencies are required to remove some of the TODO items: - A way to safely convert from byte slices to types implementing `FromBytes`, - A way to obtain slices and write into a `CoherentAllocation`, - Several improvements to the `register!()` macro, - Alignment operations to powers of two, and an equivalent to the C `fls`, - Support for `xa_alloc` in the XAlloc bindings. Some items have also become obsolete: - The auxiliary bus abstractions have been implemented and are in use, - The ELF utilities are not considered for being part of the core kernel bindings anymore. - VBIOS, falcon and GPU timer have been completed. We now have quite a few TODO entries in the code, so annotate them with a 4 letter code representing the corresponding task in `todo.rst`. This allows to easily find which part of the code corresponds to a given entry (and conversely).

2025-06-23	gpu: nova-core: extract FWSEC from BIOS and patch it to run FWSEC-FRTS	Alexandre Courbot	1	-3/+0
	The FWSEC firmware needs to be extracted from the VBIOS and patched with the desired command, as well as the right signature. Do this so we are ready to load and run this firmware into the GSP falcon and create the FRTS region.

2025-06-23	gpu: nova-core: add DMA object struct	Alexandre Courbot	1	-0/+61
	Since we will need to allocate lots of distinct memory chunks to be shared between GPU and CPU, introduce a type dedicated to that. It is a light wrapper around CoherentAllocation.
