c79cbb5952 x86: dts: Define a default TSC timer frequency
If for some reason, TSC timer frequency cannot be determined from
hardware, nor is it specified in the device tree, U-Boot will panic
resulting in endless reset during boot.

Let's define a default TSC timer frequency using the Kconfig value
CONFIG_X86_TSC_TIMER_FREQ (note: #include must be used instead of
/include/ otherwise the macro is not pre-processed).

f89e8acbc8 x86: edison: Switch to DM_USB_GADGET
DM is the modern default approach for the drivers in U-Boot.
It also allows to configure code via Device Tree.

Move Intel Edison to use DM_USB_GADGET and drop hard coded values.

Use generic Synopsys DesignWare 3 driver on Intel Edison.
For now it's just a stub which allows future refactoring.

839d66cdb5 x86: Provide default SMBIOS manufacturer/product
Add a file containing defaults for these, using the existing CONFIG
options. This file must be included with #include since it needs to
be passed through the C preprocessor.

Enable the driver for all x86 boards that generate SMBIOS tables.
Disable it for coral since it has its own driver.

2e3b883014 x86: edison: Generate an image suitable for xFSTK
It is useful to be able to flash Edison directly without relying on the
installed U-Boot being functional.

Add a binman image for this. It includes a 'OSIP' header (which happens to
look like an MBR / (Master-Boot Record), U-Boot binary and an environment.

I am not able to find a specification for OSIP.

d9b59fc9ae x86: edison: Add the rest of UARTs present on board
Intel Edison has three UART ports, i.e.
 port 0 - Bluetooth
 port 1 - auxiliary, available for general purpose use
 port 2 - debugging, usually console output is here

Enable all of them for future use.

ab83e5c1a2 x86: edison: Use proper number of serial interface
The console is actually serial #2. When we would like to enable other ports,
this would be not okay to mess up with the ordering.

Thus, fix the number of default console interface to be 2.

f26b260c69 x86: dts: edison: configure I2C#6 pins
Now that we have the pinctrl driver for Merrifield in place we can make
use of it and set I2C#6 pins appropriately.

Initial configuration came from the firmware.  Which quite likely has
been used in the phones, where that is not part of Atom peripheral, is
in use. Thus we need to override the leftover.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
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)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

495f3774be x86: Add Intel Edison board files
Add Intel Edison board which is using U-Boot.

The patch is based on work done by the following people (in alphabetical
order):
	Aiden Park <aiden.park@intel.com>
	Dukjoon Jeon <dukjoon.jeon@intel.com>
	eric.park <eric.park@intel.com>
	Fabien Chereau <fabien.chereau@intel.com>
	Felipe Balbi <felipe.balbi@linux.intel.com>
	Scott D Phillips <scott.d.phillips@intel.com>
	Sebastien Colleur <sebastienx.colleur@intel.com>
	Steve Sakoman <steve.sakoman@intel.com>
	Vincent Tinelli <vincent.tinelli@intel.com>

In case we're building for Intel Edison, we must have 4096 bytes of
zeroes in the beginning on u-boot.bin. This is done in
board/intel/edison/config.mk.

First run sets hardware_id environment variable which is read from
System Controller Unit (SCU).

Serial number (serial# environment variable) is generated based on eMMC
CID.

MAC address on USB network interface is unique to the board but kept the
same all over the time.

Set mac address from U-Boot using following scheme:
	OUI = 02:00:86
	next 3 bytes of MAC address set from eMMC serial number

This allows to have a unique mac address across reboot and flashing.
