stm32l4.git/include/arch, branch working

Added kernel-level abstraction over the spi interface.

Double the SPI bandwith by writing only 8 bits to the spi data register instead of 16 (with 8 leading 0's).

Some LED lights working. Not great. WIP

Basic SPI working.

Add module for controlling the MPU.

2020-11-25T18:32:16+00:00

The MPU is a module in arm chips which allow for memory access
protection. They are more primitive than full MMUs, but can still
provide at least basic access control between different process
controls.

Changes to painic. It now prints the stack at the time of failure (if logging is initialized).

Fix kalloc. Now the HEAP START and HEAP END globals are defined by the linker script.

Moved action to top level.

2020-11-24T20:46:41+00:00

Removed old iterations of the project and moved the files from 02-usart
to the root directory since that's the sole place where the action is
and that subproject has outgrown its initial title.
