But there's also U-Boot image here

There are two partitions for the environment ... I think you can just point
to the layout below and dont need to list it in the commit message.

This should be &&, right ?

Make this ff705000.spi.0 please , otherwise it'd be impossible to support 
multiple SPI NORs on a single QSPI controller (the mtdparts would get bound
to all of them)
