Various issues were discovered in getting Chromium OS verified boot
running on top of coreboot, booting into U-Boot.

Improvements include:
- enable serial console if even coreboot doesn't
- enable cache always
- show the BIOS date since Chromium OS's coreboot doesn't have a version
- update docs
- allow SPI driver to work without a PCH
- fix mtrr command when multi-processing (CONFIG_MP) is disabled
- add documentation about the memory map

Changes in v3:
- Fix comment to menion u-boot,dm-tpl
- Fix 'u-boot,dm-pre-tpl' (it should be u-boot,dm-tpl)

Changes in v2:
- Add a comment about the cases
- Reorder declaration and use bios_date for the variable name
- Add missing newline in the error path
- Use (ret) instead of (ret != 0) to fit with U-Boot style
- Convert table to reST format
- Add 'cros' tag since this not a generic x86 change
- Drop unnecessary patch 'Enable the cbsysinfo command'

These functions don't modify the device-ID struct that is passed in, so
mark the argument as const, so the data structure can be declared that
way. This allows it to be placed in the rodata section.

At present only bridge devices are bound before relocation, to save space
in pre-relocation memory. In some cases we do actually want to bind a
device, e.g. because it provides the console UART. Add a devicetree
binding to support this.

Use the PCI_VENDEV() macro to encode the cell value. This is present in
U-Boot but not used, so move it to the binding header-file.

At present this driver relies on coreboot to provide information about
the console UART. However if coreboot is not compiled with the UART
enabled, the information is left out. This configuration is quite
common, e.g. with shipping x86-based Chrome OS Chromebooks.

Add a way to determine the UART settings in this case, using a
hard-coded list of PCI IDs.

When booting from coreboot we may not have a PCH driver available. The
SPI driver can operate without the PCH but currently complains in this
case. Update it to continue to work normally. The only missing feature
is memory-mapping of SPI-flash contents, which is not essential.

These headers are not actually used. Drop them so that this driver can
be used by other boards, e.g. coreboot.

When starting U-Boot from a previous-stage bootloader we presumably don't
need to set up the variable MTRRs. In fact this could be harmful if the
existing settings are not what U-Boot uses.

Skip that step in this case.

These constants conflict with error codes returned by the MP
implementation when something is wrong. In particular, mp_first_cpu()
returns MP_SELECT_BSP when running without multiprocessing enabled.
Since this is -2, it is interpreted as an error by callers, which
expect a positive CPU number for the first CPU.

Correct this by using a different range for the pre-defined CPU
numbers, above zero and out of the range of possible CPU values. For
now it is safe to assume there are no more than 64K CPUs.

This fixes the 'mtrr' command when CONFIG_SMP is not enabled.

A recent change to disable cache setup when booting from coreboot
assumed that this has been done by SPL. The result is that for the
coreboot board, the cache is disabled (in start.S) and never
re-enabled.

If the cache was turned off, as it is on boards without SPL, we should
turn it back on. Add this new condition.

Add information about memory usage when U-Boot is started from coreboot.
This is useful when debugging. Also, since coreboot takes a chunk of
memory in the middle of SDRAM for use by PCI devices, it can help avoid
overwriting this with a loaded kernel by accident.

All the x86 devicetree files are built at once, whichever board is
actually being built. If coreboot is the target build, CONFIG_ROM_SIZE
is not defined and samus cannot build Chromium OS verified boot. Add
this condition to avoid errors about CONFIG_ROM_SIZE being missing.

With of-platdata-inst we want to set up a reference to each devices'
parent device, if there is one. If we find that the device has a parent
(i.e. is not a root node) but it is not in the list of devices being
written, then we cannot create the reference.

Report an error in this case, since it indicates that the parent node
is either missing a compatible string, is disabled, or perhaps does not
have any properties because it was not tagged for SPL.

Sorry, I just applied this series.

There are many commits that have a blank line between your SoB tag and
the RB tag which I believe is caused by the patman patchwork
functionality.

I have manually removed the blank lines when applying. Would you
please fix the patman?

OK thanks, I'll see what other ideas I can come up with.

I think it might have been due to using an old patman to do that
series. But I'm not sure, so I'll send a possible fix.
