/**
* @file check.h
*
* Furi crash and assert functions.
*
* The main problem with crashing is that you can't do anything without disturbing registers,
* and if you disturb registers, you won't be able to see the correct register values in the debugger.
*
* Current solution works around it by passing the message through r12 and doing some magic with registers in crash function.
* r0-r10 are stored in the ram2 on crash routine start and restored at the end.
* The only register that is going to be lost is r11.
