Currently building U-Boot as the coreboot payload requires user
to change the build configuration for a specific board during
menuconfig process. This uses the board's native device tree
to configure the hardware. For example, the device tree provides
PCI address range for the PCI host controller and U-Boot will
re-program all PCI devices' BAR to be within this range. In order
to make sure we don't mess up the hardware, we should guarantee
the range matches what coreboot programs the chipset.
But we really should make the coreboot payload support easier.
Just like EFI payload, we can create a generic coreboot payload
for all x86 boards as well. The payload is configured to include
as many generic drivers as possible. All stuff that touches low

After some thought, I believe there is an unfortunate naming flaw in
binman. Entries have a position and size, but now that we support
hierarchical sections it is unclear whether a position should be an
absolute position within the image, or a relative position within its
parent section.
At present 'position' actually means the relative position. This indicates
a need for an 'image position' for code that wants to find the location of
an entry without having to do calculations back through parents to
discover this image position.
A better name for the current 'position' or 'pos' is 'offset'. It is not
always an absolute position, but it is always an offset from its parent
offset.
It is unfortunate to rename this concept now, 18 months after binman was
introduced. However I believe it is the right thing to do. The impact is
mostly limited to binman itself and a few changes to in-tree users to
binman:
tegra
sunxi
x86
The change makes old binman definitions (e.g. downstream or out-of-tree)
incompatible if they use the 'pos = <...>' property. Later work will
adjust binman to generate an error when it is used.

Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)

In part due to community overlap, in part due to better tag visibility

initialized to correct mode by FSP. With fsp,emmc-boot-mode set to
2 (eMMC 4.1), eMMC pins are initialized to func 1, but if we set
fsp,emmc-boot-mode to 1 (auto), those pins are initialized to func 3
which is correct according to datasheet.

At present all BayTrail boards configure fsp,emmc-boot-mode to 2,
which means "eMMC 4.1" per FSP documentation. However, eMMC 4.1
only shows up on some early stepping silicon of BayTrail SoC.
Newer stepping SoC integrates an eMMC 4.5 controller. Intel FSP
provides a config option fsp,emmc-boot-mode which tells FSP which
eMMC controller it initializes. Instead of hardcoded to 2, now
we change it to 1 which means "auto".
With this change, MinnowMax board (with a D0 stepping BayTrail SoC)
can see the eMMC 4.5 controller at PCI address 00.17.00 via U-Boot
'pci' command.

This patch adds support for the congatec conga-QA3/E3845-4G eMMC8 SoM,
installed on the congatec Qseven 2.0 evaluation carrier board
(conga-QEVAL).
Its port is very similar to the MinnowboardMAX port and also uses
the Intel FSP as described in doc/README.x86.
Currently supported are the following interfaces / devices:
- UART (via Winbond legacy SuperIO chip on carrier board)
- Ethernet (PCIe Intel I210 / E1000)
- SPI including SPI NOR as boot-device
- USB 2.0
- SATA via U-Boot SCSI IF
- eMMC
- Video (HDMI output @ 800x600)
- PCIe
Not supported yet is:
- I2C
- USB 3.0

This adds basic support for chromebook_samus. This is the 2015 Pixel and
is based on an Intel broadwell platform.
Supported so far are:
- Serial
- SPI flash
- SDRAM init (with MRC cache)
- SATA
- Video (on the internal LCD panel)
- Keyboard
Various less-visible drivers are provided to make the above work (e.g. PCH,
power control and LPC).
The platform requires various binary blobs which are documented in the
README. The major missing feature is USB3 since the existing U-Boot support
does not work correctly with Intel XHCI controllers.

At present this GPIO driver still uses the legacy PCI API. Now that
we have proper PCH drivers we can use those to obtain the information
we need. While the device tree has nodes for the GPIO peripheral it is
not in the right place. It should be on the PCI bus as a sub-peripheral
of the PCH device.
Update the device tree files to show the GPIO controller within the PCH,
so that PCI access works as expected. This also adds '#address-cells'
and '#size-cells' to the PCH node.
