There is no need to keep a separate coreboot_fb.dtsi since now we
have a generic coreboot payload dts.
While we are here, this also remove the out-of-date description in
the documentation regarding to coreboot framebuffer driver with
U-Boot loaded as a payload from coreboot. As the testing result with
QEMU 2.5.0 shows, the driver just works like a charm.

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
level initialization are not allowed as such is the coreboot's
responsibility. Platform specific drivers (like gpio, spi, etc)
are not included.

Add u-boot,off-on-delay-us for fixed regulator.
Depends on board design, the gpio regulator sometimes
connects with a big capacitance. When need to off, then
on the regulator, if there is no enough delay,
the voltage does not drop to 0, so introduce this
property to handle such case.

Compressed images should have their compression property
set to "none" if U-Boot should leave them compressed.
This is especially the case for compressed ramdisks that
should be uncompressed by the kernel only.

Switch to the distro boot for UniPhier platform.
- Remove the environment vairalbes used to load images from raw
block devices.
- Keep the command to download images via tftp. This will be
useful to boot the kernel when no valid kernel image is ready
yet in the file system.
- Use root.cpio.gz instead of root.cpio.uboot because we always know
the file size of the init ramdisk; it is loaded via either a file
system or network.
- Rename fit_addr_r to kernel_addr_r, which the distro command
checks to get the load address of FIT image.

1. Since libavb library alone is highly portable, introduce dedicated
Kconfig symbol for AVB bootloader-dependent operations, so it's possible
to build libavb separately. AVB bootloader-dependent operations include:
* Helpers to process strings in order to build OS bootargs.
* Helpers to access MMC, similar to drivers/fastboot/fb_mmc.c.
* Helpers to alloc/init/free avb ops.
2. Add CONFIG_FASTBOOT dependency, as fastboot buffer is
re-used in partition verification operations.

The Linux kernel moved to sphinx-based documentation and got rid of the
DocBook based documentation quite a while ago. Hence, the DocBook
documentation for U-Boot should be converted as well.
To achieve this, import the necessary files from Linux v4.17, and
convert the current DocBook documentation (three files altogether) to
sphinx/reStructuredText.
For now, all old DocBook documentation was merged into a single
handbook, tentatively named "U-Boot Hacker Manual".
For some source files, the documentation style was changed to comply
with kernel-doc; no functional changes were applied.

the entries in /chosen/u-boot,spl-boot-order' contained a valid
image), we define (and document) /chosen/u-boot,spl-boot-device as the
property that could/should automatically be injected by SPL.

Support a default memory bank, specified in reg, as well as
board-specific memory banks in subtree board-id nodes.
This allows memory information to be provided in the device tree,
rather than hard-coded in, which will make it simpler to handle
similar devices with different memory banks, as the board-id values
or masks can be used to match devices.

At present the EFI application and payload support codes in the x86
directory is distributed in a hybrid way. For example, the Kconfig
options for both app and payload are in arch/x86/lib/efi/Kconfig,
but the source codes in the same directory get built only for
CONFIG_EFI_STUB.
This refactors the codes by consolidating all the EFI support codes
into arch/x86/cpu/efi, just like other x86 targets.

As README.x86 already mentions, there are two SPI flashes mounted
on Intel Cougar Canyon 2 board, called SPI-0 and SPI-1 respectively.
SPI-0 stores the flash descriptor and the ME firmware. SPI-1 stores
the actual BIOS image which is U-Boot. Building a single image with
both ME firmware and U-Boot does not make sense.
This also describes the exact flash location where the u-boot.rom
should be programmed in the documentation.
