Hardware modification in v1.2.0

[yzim]

The revision history in host_lld.c says,

// * v1.2.0
// - Adds 'wo/ NVMe command completion' options on auto RX/TX DMA functions
// - Fixes NVMe status controls

It seems there are other modifications, apart from vendor & device ID, and 8-channel.

Could you please offer any source code or guide on these?
Thank you!
