OpenPicoRTOS v1.8.0

[jnaulet]

Here it is ! The new OpenPicoRTOS v1.8.0 with his linker and startup files, making it a complete standalone kernel.

The only thing you need to build now is a tool chain, the rest is taken care of (mostly).

This adds a lot of flexibility as now the system is split into 3 very distinct parts:

• The architecture / cpu
• The device / mcu
• The peripheral drivers

This gives more freedom to do special blends without having to worry about working around a BSP that forces a certain memory layout or reserves some useful irq vectors for himself.

This might cause problems for people already using a BSP and are happy with it, so a v1.7.1 version offering backports is available, too.

A new architecture is supported, the TI C2000/c28x and quite a few drivers are provided.

The staging tree mostly contains risc-v related stuff as I'm still waiting for a board to test, but it builds.

A lot of bug fixes especially in the drivers (twi) complete the release.
