* Remove unnecessary checks * Sublime: never insert missing headers * Cleanup furi defines use * Cleanup startup. Cleanup linker scripts. Explicitly define all interrupts hadlers, including uninmplemented one. * Startup routine in C * Drop assembler startup * Move linker defines to stm32wb55_linker.h, cleanup naming, unify usage. Mpu: protect last 32b of main stack. Document various obscure things. * Move furi_hal_switch documentation to appropriate place, use 0x0 for updater jump. * UnitTests: move all temporary test files into tmp folder --------- Co-authored-by: SG <who.just.the.doctor@gmail.com>
