"ide_legacy_combined # TODO: Does nothing since
generations, remove from sb code?"
The "combined" mode was removed. It wasn't used by any mobo and the code for
it is almost identical to IDE one other than few bits relating to interrupt
handling and ISA mode.

All the additional work that needs to be done in EHCI BAR relocation
is independent of the hardware platform and was functionally identical
in all the copies removed.
When USBDEBUG is not selected, PCI EHCI controllers use standard
pci_dev_read_resources() call.
With USBDEBUG selected, PCI EHCI controller's device_operations
.read_resources is replaced with pci_ehci_read_resources() call,
which in turn will replace the device_operations .set_resources call.
The replacement for .set_resources reconfigures usbdebug driver side,
and calls the original .set_resources to configure hardware side.

Therefore, setting the xHCI BAR to 0xe8001000 worked the same like
setting it to 0xe8000000, as bit12 is reserved and ignored. This again
interfered with the MMIO space of the first EHCI controller and broke
S3 resume on Ivy Bridge.
AFAIK, the MRC ignores the setting of the xHCI BAR, anyway. So just drop

On newer Intel systems, the flash ROM is shared between the host
processor (BIOS), it's Management Engine (ME) and an integrated ethernet
controller (GbE). The layout of the flash ROM (and other information) is
kept in the so called Intel Firmware Descriptor (IFD). If we only want
to build coreboot to update the BIOS section, all we need is the flash
layout.
This patch adds the option to specify the flash layout in the
mainboard's Kconfig, and thus, to build without the real IFD. However,
with such a build, one has to make sure that the IFD section on the
flash ROM won't be written over (nor any other section that hasn't been
included by coreboot). A patch to write selected sections of a flash ROM
with IFD has been sent to the flashrom mailing list [1].

For reasons of security and testing we want to be able to
enable/disable ME section locking through a config option.

Right now coreboot's build process produces images that are
not booting on actual hardware because they are smaller than
the actual flash device and also don't have an IFD nor an ME
firmware in them. In order to produce bootable images, you
needed a wrapper script / extra step until now. With this
change, the resulting coreboot.rom is actually bootable.

This is a basic romstage driver that can be used for the
MRC cache code on systems where we do not have the MRC cache
stored in a flash region that is memory mapped.
It uses the hardware sequencing interface to avoid having
to know anything about the flash chip itself.
BUG=chrome-os-partner:15031
BRANCH=stout
TEST=manual: this was tested with debug code added to romstage
that attempted to read the MRC cache at offset 0x3e0000.

- Fix handling of 5-byte Fast Read command in the ICH SPI
driver. This fix is ported from the U-boot driver.
- Allow CONFIG_SPI_FLASH_NO_FAST_READ to be overridden by
defining a name for the bool in Kconfig and removing the
forced select in southbridge config
- Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers
to use #if instead of #ifdef
- Relocate flash functions in SMM so they are usable.
This really only needs to happen for read function pointer
since it uses a global function rather than a static one from
the chip, but it is good to ensure the rest are set up
correctly as well.

The Intel PCH can override the ASPM settings via the MPC2 register.
Add a chip override for F0-F7. Mainboards may implement this as
needed.
This also fixes the final PM setup being done too early. It was
being done prior to the PCIe ASPM setup, which happens in the
bridge scan.
