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.

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.

Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.
In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".
Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.
With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

taking into consideration that GPIO and pin control are *different* IPs
on Intel Tangier, we need to supply numbers properly.
Besides that, it improves user experience since the official documentation
for Intel Edison board is referring to GPIO hardware numbering scheme.

This patch removes the inclusion of the libgcc math functions and
replaces them by functions coded in C, taken from the coreboot
project. This makes U-Boot building more independent from the toolchain
installed / available on the build system.
The code taken from coreboot is authored from Vadim Bendebury
<vbendeb@chromium.org> on 2014-11-28 and committed with commit
ID e63990ef [libpayload: provide basic 64bit division implementation]

This reverts commit 13c531e52a.
The error message with FIT style image mentioned in the above commit
only happens when booting using FIT image containing bzImage kernel
and without setup node (setup.bin). The current documentation for
x86 FIT support in doc/uImage.FIT/x86-fit-boot.txt mentions that
kernel's setup.bin file is required for building x86 FIT images.
The above commit breaks FIT images generated as described in the

Currently, pylibfdt is always compiled if swig is installed on your
machine. It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.
"checkbinman" and "checkdtoc" are wrong. It is odd that the final
build stage checks if we have built necessary tools. If your platform
depends on dtoc/binman, you must be able to build pylibfdt. If swig
is not installed, it should fail immediately.
I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be
property select:ed by platforms that need them. Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

It was observed that when booting Linux kernel on Intel Cherry Hill
board, unexpected crash happens quite randomly. Sometimes kernel
just oops, while sometimes kernel throws MCE errors and hangs:
mce: [Hardware Error]: Machine check events logged
mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: c400000000010151
mce: [Hardware Error]: TSC 0 ADDR 130f3f2c0
mce: [Hardware Error]: PROCESSOR 0:406c3 TIME 1508160686 SOCKET 0 APIC 0 microcode 363
This looks like a hardware error per mcelog. After debugging, it
seems turning off turbo mode on the processor does not expose this
behavior, although U-Boot runs OK with turbo mode on. Suspect it is
related to an errata of Braswell processor.
To fix this, remove the Braswell cpu driver which does the turbo
mode configuration, and switch to use the generic cpu-x86 driver.
Also there is a configuration option in the FSP that turns on the
turbo mode and that has been turned off too.

Azalia configuration may be different across boards, hence it's not

It was observed that when booting a Ubuntu 16.04 kernel, doing ACPI
S3 suspend/resume sometimes causes the Ubuntu kernel hang forever.
The issue is however not reproduced with a kernel built from i386/
x86_64 defconfig configuration.
The unstability is actually caused by unexpected interrupts being
generated during the S3 resume. For some unknown reason, FSP (gold4)
for BayTrail configures the GPIO DFX5 PAD to enable level interrupt
(bit 24 and 25). As this pin keeps generating interrupts during an
S3 resume, and there is no IRQ requester in the kernel to handle it,
the kernel seems to hang and does not continue resuming.
Clear the mysterious interrupt bits for this pin.

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
