Ulaş Sertan Kemeç cd4fe549ee arch/arm/am67: Add a RAT sliding window for 36-bit DDR access. ... J722S maps DDR above the first 2 GB at 0x8_8000_0000, out of reach of the 32-bit R5F, while a 64-bit Linux peer posts virtio buffers there. Dedicates RAT region 0 as a 16 MB window at 0xFE000000. am67_rat_map() re-aims it and returns a pointer plus the bytes left before the edge, so callers can split copies that straddle it. The window is Non-cacheable, since it retargets at runtime and cached lines would alias across physical blocks. A mapping is valid only until the next call; the sole user, vhost-net, is serialised on the netdev work thread.
