The stacks are interleaved for each core? Just curious, is this common practice for SMP systems? |

I couldn't think of a way to allocate the space for N CPUs in the linker script without doing it this way. I cannot remember where I got the idea from, but I definitely saw it somewhere. |
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.

Moves the SMP example to its own example folder, and allocates stacks for all cores.
This makes it easier to share code across multiple SMP examples when adding more SMP examples in the future.
