[U-Boot] [PATCH 00/26] x86: Initial ACPI support for Intel BayTrail

This series introduces initial ACPI support for Intel BayTrail.

Advanced Configuration and Power Interface (ACPI) aims to establish
industry-standard interfaces enabling OS-directed configuration, power
management, and thermal management of mobile, desktop, and server platforms.

Linux can boot without ACPI with "acpi=off" command line parameter, but
with ACPI the kernel gains the capabilities to handle power management.
For Windows, ACPI is a must-have firmware feature since Windows Vista.
CONFIG_GENERATE_ACPI_TABLE is the config option to turn on ACPI support in
U-Boot. This requires Intel ACPI compiler to be installed on your host to
compile ACPI DSDT table written in ASL format to AML format. You can get
the compiler via "apt-get install iasl" if you are on Ubuntu or download
the source from acpica website to compile one by yourself.

Current ACPI support in U-Boot is not complete. More features will be added
in the future. The status as of today is:

* Support generating RSDT, XSDT, FACS, FADT, MADT, MCFG tables.
* Support one static DSDT table only, compiled by Intel ACPI compiler.
* Support S0/S5 only, no S3/S4 boot path support yet.
* No ACPI global NVS support (this can be optional, but we may need it in
the future to simplify ASL code logic when utilizing NVS variables).
* No dynamic AML bytecodes insertion at run-time (this is optional as we
can always describe the board in the static way).
* All ACPI interrupts are routed to SCI for OS to handle. No legacy SMI
implementation within U-Boot.
* Install Ubuntu from U-Boot plus SeaBIOS does not work.
* Install Windows 8.1/10 from U-Boot plus SeaBIOS does not work.

So far ACPI is enabled on BayTrail based boards. Testing was done by booting
a pre-installed Ubuntu 14.04 from a SATA drive. Most devices seem to work
correctly and the board can respond a reboot/shutdown command from Ubuntu.

This series is available at u-boot-x86/acpi-working.
