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.
Only tested on Armv8-R because Rust's Armv7-A targets don't have virtualization support enabled.
Also expands ISS decoding for HSR.

Adds another batch of examples which all run at EL2.
eret, so a while new batch of assembly trampolines were requiredaarch32-rtto enable these new EL2 trampolines. This feature also skips putting you into EL1 automatically.Requires #127 and #119
