* [metal] Add a uprintf() routine, for non-emergency boot logging * [metal] _Really_ push forward timing of VGA TTY initialization * [metal] Do something useful with uprintf() * [metal] Locate some ACPI tables, for later hardware detection Specifically the code now tries to find the ACPI RSDP, RSDT/XSDT, FADT, & MADT tables, whether in legacy BIOS bootup mode or in a UEFI bootup. These are useful for figuring out how to (re)enable asynchronous interrupts in legacy 8259 PIC mode.
