After this patch, the Kernel and U-boot device tree settings for

"
According to AM335x TRM, Document spruh73l, Revised February 2015,
Section 9.2.2 Pad Control Registers, setting bit 6 of the pad control
registers actually sets the SLEWCTRL value to slow rather than fast as
the current macro indicates. Introduce a new macro, SLEWCTRL_SLOW, that
sets the bit, and modify SLEWCTRL_FAST to 0 but keep it for
completeness. Current users of the macro (i2c and mdio) are left
unmodified as SLEWCTRL_FAST was the macro used and actual desired state.

ARM: tegra: avoid more operations in non-secure world
A secure monitor that runs before U-Boot, and hence causes U-Boot to run
in non-secure world, must implement a few operations that U-Boot
otherwise implements when running in secure world. Fix U-Boot to skip
these operations when running in non-secure world. In particular:
- The secure monitor must provide the LP0 resume code and own LP0
configuration in order to maintain security, so must initialize all
the PMC scratch registers used by the boot ROM during LP0 resume.
Consequently, U-Boot should not attempt to clear those registers,
since the register accesses will fail or cause an error.
- The secure monitor owns system security, and so is responsible for
configuring security-related items such as the VPR.

In some cases it can be useful to be able to bind a device to a driver from

The obvious example is for versatile devices such as USB gadget.
Another use case is when the devices are not yet ready at startup and

usage example:
bind usb_dev_generic 0 usb_ether
unbind usb_dev_generic 0 usb_ether
or
unbind eth 1

Also add a 'drv' parameter to filter the children to remove/unbind.

bind/unbind commands.

x86: tsc: Try hardware calibration first
At present if TSC frequency is provided in the device tree, it takes
precedence over hardware calibration result. This swaps the order to
try hardware calibration first and uses device tree as last resort.
This can be helpful when a generic dts (eg: coreboot/efi payload) is
supposed to work on as many hardware as possible, including emulators
like QEMU where TSC hardware calibration sometimes fails.

x86: dts: Remove coreboot_fb.dtsi
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While we are here, this also remove the out-of-date description in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.

x86: coreboot: Add generic coreboot payload support
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.

Makefile: Don't generate position independent code
Since gcc-8 the --enable-default-pie starts producing code which assembler
can't translate in case of U-Boot. The build fails with
{standard input}: Assembler messages:
{standard input}:21100: Error: junk at end of line, first unrecognized character is `@'
{standard input}:21120: Error: junk at end of line, first unrecognized character is `@'
and so on.
This is usually the case for x86 platform because in many cases it uses host
compiler from the Linux distributions, where PIE is enabled by default.
Previously (gcc-7 and earlier) that was a potential issue due to absence of
constructions like
.long end.5561@gotoff-start.5558@gotoff
which are a cause of above error messages in gcc-8.
Fix all these by disabling PIE on Makefile level.

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.

Migrate bootlimit to Kconfig
Migrate boards which set bootlimit in the environment to Kconfig.
We exclude gurnard_defconfig which includes a bootlimit=, but doesn't set
CONFIG_BOOTCOUNT_LIMIT, so we'd fail to include a bootlimit setting
if we migrated it.
display5_defconfig and display5_factory_defconfig share a SYS_CONFIG_NAME,
but only display5_defconfig enables CONFIG_BOOTCOUNT_LIMIT, so we fail to
set bootlimit= in display5_factory_defconfig. This is okay because the
display5_factory_defconfig doesn't need to have it set, as it is only
meant to prepare the board in the factory.
Environment changes for all modified configs as seen from buildman:
boards.cfg is up to date. Nothing to do.
