CPU_MICROCODE_IN_CBFS was designed to mean that loading microcode updates
from a CBFS file is supported, however, the name implies that microcode is
present in CBFS. This has recently caused confusion both with contributions
from Google, as well as SAGE. Rename this option to
SUPPORT_CPU_UCODE_IN_CBFS in order to make it clearer that what is meant is
"hey, the code we have for this CPU supports loading microcode updates from
CBFS", and prevent further confusion.

Now that we have horizontal display areas that are not multiples of 32 bytes,
things are more complex. We add three struct members (x, y resolution and
bytes per line) which are to be filled in by the mainboard as it sets the mode.
In future, the EDID code may take a stab at initializing these but the values are
context-dependent.

The SystemAgent contains a mini-hd audio controller at PCI 0:3.0
which uses the same verb table init sequence as the southbridge.
In order to avoid two copies of the verb table loading code I
separated out the HDA verb table functions into a file that can
be re-used and then added a minihd driver to the haswell northbridge.
The minihd verb table is the same across devices so it can live
within the minihd driver rather than needing to be specified in
each separate mainboard.
I also fixed up the driver for lynxpoint HDA by following the
reference code.
Without HDMI cable plugged in driver does not find any codec,
and it does not seem to re-probe when HDMI is connected. We may
be missing kernel patches for this.
hda-intel 0000:00:03.0: no codecs found!
With a basic kernel patch to add 0x0a0c device ID to HDA driver
and with HDMI cable connected it is much happier:

walkcbfs() is used only with ROMCC. Besides finding stages during the
bootblock, it's also used when applying microcode updates during the
bootblock phase. The function used to return only a pointer to the data of
the CBFS file, while making the header completely inaccessible. Since the
header contains the length of the CBFS file, the caller did not have a way
to know how long the data was. Then, other conventions had to be used to
determine the EOF, which might present problems if the user replaces the
CBFS file. This is not an issue when jumping to a stage (romstage), but can
present problems when accessing a microcode file which has not been
NULL-terminated.
Refactor walkcbfs_asm to return a pointer to the CBFS file header rather
than the data. Rename walkcbfs() to walkcbfs_head(), and reimplement a new
walkcbfs() based on walkcbfs_head(). Thus current usage of walkcbfs()
remains unaffected.
The code has been verified to run successfully under qemu.
Subsequent patches will change usage of walkcbfs() to walkcbfs_head where
knowing the length of the data is needed.

During the update_fit step, 'file_length' is used to determine how many
bytes are left in the CBFS file. It was decremented in a loop from an
array 'mcus[num_mcus].size', but 'num_mcus' was incremented right before.
Since 'mcus' is memset(0) externally, 'file_length' was never decremented.
The loop exited when it reached a dummy terminator, usually 48 bytes of 0
which are internationally added to microcode blobs in coreboot. However,
if that terminator is removed, the loop doesn't stop and continues until
it segfaults.

Newer mainboards that use haswell -- and, presumably, chipsets to come -- need
some support functions. Add them in the drivers/intel/gma directory.
Currently, this is one file: intel_ddi.c, but more may come.
Compilation of this file is controlled by INTEL_DDI, defined
in the Kconfig as default n and used in the Makefile.inc

Add ACPI Methods to enable and disable power limiting with PL1.
This can be used in ACPI Thermal Zone or in EC ACPI _QXX events.
This commit adds new unused methods and is fully tested with the
subsequent commit that makes use of these methods.

1) fix enable of power aware interrupt routing
2) set BIOS_RESET_CPL to 3 instead of 1
3) mirror PKG power limit values from MSR to MMIO on all SKUs
4) mirror DDR power limit values from MMIO to MSR
5) remove DMI settings that were from snb/ivb as they do
not apply to haswell
1) verify power aware interrupt routing is working by looking
in /proc/interrupts to see interrupts routed to both cores
instead of always to core0
BEFORE: 58: 4943 0 PCI-MSI-edge ahci
AFTER: 58: 4766 334 PCI-MSI-edge ahci
2) read back BIOS_RESET_CPL to verify it is == 3
localhost ~ # iotools mmio_read32 0xfed15da8
0x00000003
3) read PKG power limit from MMIO and verify it is the same
as the MSR value
localhost ~ # rdmsr 0 0x610
0x0000809600dc8078
localhost ~ # iotools mmio_read32 0xfed159a0

localhost ~ # iotools mmio_read32 0xfed159a4

4) read DDR power limit from MSR and verify it is the same
as the MMIO value (note this is zero based on current MRC input)

Limit power to 12W at 73C and remove limit at 68C.
To have the CPU consume maximum power it is necessary to stress
both the CPU and the GPU. Bastion (chrome.supergiantgames.com)
and/or webglsamples.googlecode.com can be useful for this.
Testing this properly requires a script to report the running
average power readings. The watch_power.sh script is attached
to this issue in the partner tracker.
1) Run watch_power.sh continuously:
localhost ~ # watch -n 0 bash -e /tmp/watch_power.sh
2) Start Bastion (or other stress apps). The power draw should
be close to 15W if under enough load.
3) Watch until temperature climbs above 73C and is caught by
the thermal zone 10 second poll, this can be sped up by blocking
or removing the fan.
4) The ACPI thermal zone states should change to reflect that
active[2] is now enabled and power consumption should drop to 12W.
5) Stop the stress apps and wait until the CPU cools off again,
enable the fan again if it was removed.
6) The ACPI thermal zone state should switch back to active[3].

The elog code calculates flash offsets and their equivalent
addresses in the memory address space. However, it assumes
the detected flash size is entirely mapped into the address
space. This can lead to incorrect calculations. Add code
to allow ROM_SIZE to be less than detected flash size. The
underlying assumption is that the first ROM_SIZE bytes are
programmed into the larger device.
