c0434407b5 board_f: Use static print_cpuinfo if CONFIG_CPU is active
When the DM CPU drivers are active, printing information about a CPU
should be delegated to a matching driver.

Hence, add a static print_cpuinfo that implements this delegation when
DM CPU drivers are active.

23471aed5c board_f: Add reset status printing
To print the reset status during boot, add a method print_resetinfo to
board_f, which is called in init_sequence_f[], that gets the reset

reasonable), and prints it.

245f5cda69 sysreset: Add get_status method
It's useful to have the reset status of the SoC printed out during reset
(e.g. to learn whether the reset was caused by software or a watchdog).

As a first step to implement this, add a get_status method to the
sysreset class, which enables the caller to get printable information
about the reset status (akin to get_desc in the CPU uclass).

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.

355c9b757e x86: tangier: pinmux: add API to configure protected pins
This API is going to be used to configure some pins that are protected
for simple modification.

It's not a comprehensive pinctrl driver but can be turned into one
when we need this in the future. Now it is planned to be used only
in one place. So that's why I decided not to pollute the codebase with a
full-blown pinctrl-merrifield nobody will use.

This driver reads corresponding fields in DT and configures pins
accordingly.

The "protected" flag is used to distinguish configuration of SCU-owned
pins from the ordinary ones.

The code has been adapted from Linux work done by Andy Shevchenko
in pinctrl-merrfifield.c
