  * S3 (Suspend to RAM), S4 (Suspend to Disk).
 
 Features that are optional:
- * ACPI global NVS support. We may need it to simplify ASL code logic if
-   utilizing NVS variables. Most likely we will need this sooner or later.
  * Dynamic AML bytecodes insertion at run-time. We may need this to support
    SSDT table generation and DSDT fix up.
  * SMI support. Since U-Boot is a modern bootloader, we don't want to bring
    those legacy stuff into U-Boot. ACPI spec allows a system that does not
    support SMI (a legacy-free system).

+ACPI was initially enabled on BayTrail based boards. Testing was done by booting
 a pre-installed Ubuntu 14.04 from a SATA drive. Installing Ubuntu 14.04 and
 Windows 8.1/10 to a SATA drive and booting from there is also tested. Most
 devices seem to work correctly and the board can respond a reboot/shutdown
 command from the OS.
 
+For other platform boards, ACPI support status can be checked by examining their
+board defconfig files to see if CONFIG_GENERATE_ACPI_TABLE is set to y.
