Geert Uytterhoeven b2e34f5faf orangecrab: Fix r0.1 user_led mapping
On r0.1, all three user_leds are mapped to the same pin.
Fix this by mapping them to the pins connected to the individual
channels of the RGB LED, to match the comments, the schematics, and the
spirit of r0.2.

Untested on real hardware (I have r0.2 only).

Fixes: c94cbae0c0 ("orangecrab: add user_led (RGB leds), DFUProg and --load support.")

Florent Kermarrec beccecf59f orangecrab: reduce DDR3 power consumption/heat and get back USB PLL to CRGSDRAM.
- disable DQ termination.
- disable RTT_NOM.
- drive VCCIO/GND pads.

Reduce current from 0.25A to 0.12A with: ./orangecrab.py --uart-name=usb_acm --sys-clk-freq=48e6.
Still working at 96MHz, 0.17A with: ./orangecrab.py --uart-name=usb_acm --sys-clk-freq=96e6.

See https://github.com/enjoy-digital/litedram/issues/216.

Florent Kermarrec 1f88a9d5ec platforms: make sure clocks inputs are constraints on all platforms.
Also use new loose lookup_request to simplify constraints.

Florent Kermarrec 8211aca2e8 Avoid Official/Partner/Community differentiation: use same directory for all platforms/targets.
We initially wanted to provide different level of support for the platforms/targets, mainly
to avoid too much maintenance and let each contributor update its contributed platforms and
targets, but it's easier to update all platforms/targets all-together when LiteX evolves or
changes (and that's what has been done on litex-boards since the creation of the repository).
So let just simplify things and avoid this differentiation.
