32   * bhyve ACPI table generator.
33   *
34   * Create the minimal set of ACPI tables required to boot FreeBSD (and
35   * hopefully other o/s's) by writing out ASL template files for each of
36   * the tables and the compiling them to AML with the Intel iasl compiler.
37   * The AML files are then read into guest memory.
38   *
39   *  The tables are placed in the guest's ROM area just below 1MB physical,
40   * above the MPTable.
41   *
42   *  Layout (No longer correct at FADT and beyond due to properly
43   *  calculating the size of the MADT to allow for changes to
44   *  VM_MAXCPU above 21 which overflows this layout.)
45   *  ------
46   *   RSDP  ->   0xf2400    (36 bytes fixed)
47   *     RSDT  ->   0xf2440    (36 bytes + 4*7 table addrs, 4 used)
48   *     XSDT  ->   0xf2480    (36 bytes + 8*7 table addrs, 4 used)
49   *       MADT  ->   0xf2500  (depends on #CPUs)
50   *       FADT  ->   0xf2600  (268 bytes)
51   *       HPET  ->   0xf2740  (56 bytes)
52   *       MCFG  ->   0xf2780  (60 bytes)
53   *         FACS  ->   0xf27C0 (64 bytes)
54   *         DSDT  ->   0xf2800 (variable - can go up to 0x100000)
