They are submitted separately as they do not depend on the command queue work, and are valuable on their own. Patches 1 to 4 make the generic bootloader its own type, usable with any DMEM descriptor and not just FWSEC's, and place it at the top of IMEM as reported by the HWCFG register instead of assuming a 64 KiB IMEM. Patches 5 to 7 let falcon DMA transfers read from a framebuffer address and tag DMEM blocks, and check the per-block offsets for overflow. These three are extracted from a single commit into their own patches. Apart from the bootloader placement, no functional change is introduced by this series. The new DMA capabilities remain unused until the r000 load-and-execute handlers land. Based on `drm-rust-next`, tested with TU106 and GA107 using both the 570.144 and 615.71.09 firmware images.
