hexagon: overhaul of buffer and DMA handling to support 64bit mappings + improvements (#29197) hex-dma64: enable support extended buffer mappings and 64bit dma hex-dma64: expand binary ops to support more DMA scenarios hex-dma64: add binary-ops.h hex-dma64: add --hex-dma64 to run.py and fix minor issues hex-dma64: update SSM_CONV to use dma with proper support for 64bit hex-ops: remove obsolete gate for % 128 in binary ops hex-l2: dont check weight tensors against dirty ranges hex-dma64: most binary ops now support dma hex-dma: use dma_addr_t instead of plain uint64_t to avoid overhead on older targets hex-dma: update all dma users to use dma_data (instead of pointers) hex-dma64: simplify lazy buffer mapping and clonning hex-fusion: factor out try_fuse_common that checks for dma64 buffers hex-bufs: minor cleanup for mmaping logic hex-bufs: simplify buffer clonning hex-ssm-conv: tighten gating checks and check vtcm size in kparams hex-binary: fix incorred mod/wrap in scalar ops hex-binary: make sure to call precompute kparams in support checks hex-dma64: update addr handling in mm,concat,binary hex-dma64: fixing up leftover of dma_addr_t conversion hex-binary: redo the kernel…
