rom_bootrom_state_reset() function

Reset bootrom state Resets internal bootrom state, based on the following flags: STATE_RESET_CURRENT_CORE - Resets any internal bootrom state for the current core into a clean state. This method should be called prior to calling any other bootrom APIs on the current core, and is called automatically by the bootrom during normal boot of core 0 and launch of code on core 1. STATE_RESET_OTHER_CORE - Resets any internal bootrom state for the other core into a clean state. This is generally called by a debugger when resetting the state of one core via code running on the other. STATE_RESET_GLOBAL_STATE - Resets all non core-specific state, including: Disables access to bootrom APIs from ARM-NS Unlocks all BOOT spinlocks Clears any secure code callbacks Note: the sdk calls this method on runtime initialisation to put the bootrom into a known state. This allows the program to function correctly if it is entered (e.g. from a debugger) without taking the usual boot path (which resets the state appropriately itself).
