BTW It would be much better for these to be ordered, - Emulator - DTS - Kernel - Root FS Emulator + DTS could be needed for non-Linux applications /...

Modernize the PLL generation inside CRG files

2

LiteX has gained the ability to easily create PLL objects. See https://github.com/timvideos/litex-buildenv/blob/master/targets/arty/crg.py for example. Convert all the PLL generation in crg.py files to use this new method.
