Can you also add a sandbox test for this command?

C code:

console_record_reset();
run_command("acpi list", 0);
addr = (ulong)map_to_sysmem(buf);
ut_assert_nextline("ACPI tables start at %lx", addr);
ut_assert_nextline("RSDP %08lx %06lx (v02 U-BOOT)", addr,
   sizeof(struct acpi_rsdp));
...
ut_assert_console_end();

Simon
