The steps required to boot a Linux distribution from U-Boot on x86 are not
very complicated, but it is a good idea to have these written down in an
accessible place.
Document how to examine the boot media from U-Boot, how to load a kernel,
load a ramdisk, set the kernel boot arguments and start the kernel. With
these instructions Ubuntu boots mostly normally on Minnowmax.
Note that the TSC timer does not operate correctly and gives warnings in
the boot log. I expect that ACPI support will solve this.

FASTBOOT is defined both by CONFIG_USB_FUNCTION_FASTBOOT AND CONFIG_CMD_FASTBOOT, so it doesn't
make much sense to have a CONFIG_USB_FASTBOOT prefix for fastboot-specific options, especially
given that other config options for fastboot use the CONFIG_FASTBOOT prefix.
This replaces the CONFIG_USB_FASTBOOT prefix with CONFIG_FASTBOOT, for consistency.

This introduces a coherent scheme for naming USB download gadget and functions

To try to reduce the pain of confusion of binary blobs, add MD5 checksums

These defines for a 2nd autoboot stop and delay string are nearly unused. Only
sc3 defines CONFIG_AUTOBOOT_DELAY_STR2. And a patch to remove this most likely
unmaintained board is also posted to the list.
By removing these defines the code will become cleaner and moving the remaining
compile options to Kconfig will get easier.

Before device-tree, the device serial number used to be passed to the kernel
using ATAGs (on ARM). This is now deprecated and all the handover to the kernel
should now be done using device-tree. Thus, this passes the serial-number
property to the kernel using the serial-number property of the root node, as
expected by the kernel.
The serial number is a string that somewhat represents the device's serial
number. It might come from some form of storage (e.g. an eeprom) and be
programmed at factory-time by the manufacturer or come from identification
bits available in e.g. the SoC.

Prior to this commit, ZC702 and ZC706 shared the same configuration
and were built as follows:
ZC702: make zynq_zc70x_defconfig && make
ZC706: make zynq_zc70x_defconfig && make DEVICE_TREE=zynq-zc706
This commit introduces separate configuration for them, which makes
the next commit much easier.
Going forward, the recommended build commands are:
ZC702: make zynq_zc702_defconfig && make
ZC706: make zynq_zc706_defconfig && make
Although the old work flow is still supported, CONFIG_TARGET_ZC70X
has been marked as deprecated. If used, the warning message is
shown to prompt users to switch to the new scheme.

This commit adds emulation of sandbox PMIC device, which includes:
- PMIC I2C emulation driver
- PMIC I/O driver (UCLASS_PMIC)
- PMIC regulator driver (UCLASS_REGULATOR)
The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes,
which allows using 'i2c md' command with the default count (16).
The sandbox PMIC provides regulators:
- 2x BUCK
- 2x LDO
Each, with adjustable output:
- Enable state
- Voltage
- Current limit (LDO1/BUCK1 only)
- Operation mode (different for BUCK and LDO)
Each attribute has it's own register, beside the enable state, which depends
on operation mode.
The header file: sandbox_pmic.h includes PMIC's default register values,
which are set on i2c pmic emul driver's probe() method.
