/*
* This code here implements a warmboot exploit. Hotboot, that's so hot, it burns Nvidia once again.
* In the bootrom if the boot_rom_patch_control's highest bit set it uses it as an index to
* APB_MISC_BASE (u32 array) and sets it to boot_rom_patch_data.
* (The hightes bit falls out when it gets multiplied by sizeof(u32) aka. 4).
* Because the bootrom misses the boundary checks, it lets us write anywhere, anything.
* Ipatch hardware lets us apply 12 changes to the bootrom and can be changed any time.
* The first patch is not needed anymore when the bug triggers, so we overwrite that.
* 0x10459E is the address where it returns error when the signature is worng.
* We change it to `MOV R0, #0`(0x2000), so we pass that check.
*
* Note: The modulus in the warmboot header is still validated.
