Thanks for the review. Based on this I've also fixed my 757i-eval BSP 
variant submission. The fixes are (as you requested).

- linkcmds files with + replaced by _
- license clarification on system_stm32h7xx.c file

Otherwise the series is as you reviewed.

I hope there will be no more troubles with this one, once you OK it, 
I'll pack patch tarball for Joel for push.

Thanks!
