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
43  *  ------
44  *   RSDP  ->   0xf2400    (36 bytes fixed)
45  *     RSDT  ->   0xf2440    (36 bytes + 4*7 table addrs, 4 used)
46  *     XSDT  ->   0xf2480    (36 bytes + 8*7 table addrs, 4 used)
47  *       MADT  ->   0xf2500  (depends on #CPUs)
48  *       FADT  ->   0xf2600  (268 bytes)
49  *       HPET  ->   0xf2740  (56 bytes)
50  *       MCFG  ->   0xf2780  (60 bytes)
51  *         FACS  ->   0xf27C0 (64 bytes)
52  *         DSDT  ->   0xf2800 (variable - can go up to 0x100000)
