[U-Boot] [EXT] Re: [PATCH 0/1] NVME fix PRP Offset Invalid

[Aaron Williams]

Thanks. I'm still trying to figure out why my patch isn't showing up in the 
mailing list. Without it I can easily cause my Samsung NVME drive to
fail with the status containing 0x2013 when doing large writes in a FAT
filesystem (but for some reason not reads). I also could not reproduce
this with an Intel NVME card.

The error code is valid, however, since the PRP is not page aligned.

Ideally the NVME driver could use SGLs instead of PRPs except in architectures 
that need PRPs. I would think PSDT=2 would work better for this.
