Will make it easier to add other tests, like sharing the GIC across cores.
We send a Software Generated Interrupt from Core 0 to Core 1, and then another one back the other way.
* The `_num_cores` symbol controls how many copies of each stack you get * Added better docs to link.x * Added `enum Stack` to aarch32-rt, which can fetch information about each stack * Simplified the SMP start-up code * Stacks and stack related code are now all in the same order If you want to put stacks into TCM, you'll need custom routines. This code assumes stacks all live in the same region of RAM.
The parser thought the hyphen started a bullet list.
* Add an API to get the various linker output sections (aarch32_rt::region) * Adjust link.x to allow for adjustable alignment of regions * Adjust link.x to allow for adjustable padding between stacks * Add an example that programs the MPU

Make it easier to set up the MPU
The MPS3-AN536 padding is set at 64K, so that the normal build and the +d32 build end up with the same memory map (otherwise their output for the mpu_region example would be different).
Includes #127
