Tweak C/CXX_FLAGS to separate language standard used for C and C++ files.
Added SCU pinmux data for USB LEDs, configured USB LEDs to be outputs (not float).
PLL1 was misconfigured to run at 408MHz (way out of spec) instead of 204MHz. Corrected this by using DIRECT=1 instead of FBSEL=1.
Slowed down edges on LED and power enable signals -- they don't need to be fast, and this *might* have a negligible but positive effect on noise.
Oops, read PLL1 documentation again. Looks like FBSEL=1 is for "normal operation". So include that, but use DIRECT=1 to skip the PSEL divider (which would prevent us producing 204MHz from an in-spec PLL frequency).
