11955590a2 dts: renamed FIT_EMBED to MULTI_DTB_FIT and moved it to the dts Kconfig
CONFIG_FIT_EMBED might be confused with CONFIG_OF_EMBED, rename it
MULTI_DTB_FIT as it is able to get a DTB from a FIT image containing
multiple DTBs. Also move the option to the Kconfig dedicated to the DTS
options and create a README for this feature.

148a139d65 bootstage: adjust Makefile to allow including bootstage in SPL, but not in TPL
For timing our bootstages on the RK3368, which has a minimal TPL
(and where we consequently don't want to time the bootstages) and a
full-featured SPL (where we can bootstage recording), we need to
adjust the Makefile.

Use the $(SPL_TPL_) macro in the Makefile for bootstage.o

f94e643ef9 spl: consistently use $(SPL_TPL_) to select features for SPL and TPL builds
To allow for a finer-grained control of features for TPL and SPL
builds all modules/boot-methods/etc. need to be consistently selected
based on the $(SPL_TPL_) macros.

This allows splitting the associated config-options in Kconfig: we
don't split the Kconfig options here and now, as this should happen on
an as-needed basis, whenever someone needs a feature/boot-method/etc.
in their TPL.

f1896c45cb spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN
Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

.../common/cli_readline.c:20:21: warning: ‘tab_seq’ defined but not used [-Wunused-const-variable=]

Because in SPL we're normally not doing interactive commands anyhow, so
lets just not compile this at all in SPL.  This also means that we need
to correct the logic (and comment) about what the drivers/ddr/fsl/ and
CONFIG_FSL_DDR_INTERACTIVE requires and this will be included in SPL

41598c8251 autoboot: add CONFIG_AUTOBOOT to allow to not compile autoboot.c
Since commit bb597c0eeb ("common: bootdelay: move CONFIG_BOOTDELAY
into a Kconfig option"), CONFIG_BOOTDELAY is defined for all boards.

Prior to that commit, it was allowed to unset CONFIG_BOOTDELAY to
not compile common/autoboot.c, as described in common/Makefile:

  # This option is not just y/n - it can have a numeric value
  ifdef CONFIG_BOOTDELAY
  obj-y += autoboot.o
  endif

It was a bit odd to enable/disable code with an integer type option,
but it was how this option worked before that commit, and several
boards actually unset it to opt out of the autoboot feature.

This commit adds a new bool option, CONFIG_AUTOBOOT, and makes
CONFIG_BOOTDELAY depend on it.

I chose "default y" for this option because most boards use the
autoboot.  I added "# CONFIG_AUTOBOOT is not set" for the boards that
had not set CONFIG_BOOTDELAY prior to the bad commit.

And the following booleans:

aa9e604410 cmd: eeprom: add support for layout aware commands
Introduce the (optional) eeprom print and eeprom update commands.

These commands are eeprom layout aware:
* The eeprom print command prints the contents of the eeprom in a human
  readable way (eeprom layout fields, and data formatted to be fit for human
  consumption).
* The eeprom update command allows user to update eeprom fields by specifying
  the field name, and providing the new data in a human readable format (same
  format as displayed by the eeprom print command).
* Both commands can either auto detect the layout, or be told which layout to
  use.

New CONFIG options:
CONFIG_CMD_EEPROM_LAYOUT - enables commands.
CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported

Feature API:
__weak int parse_layout_version(char *str)
	- override to provide your own layout name parsing
__weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version);
	- override to setup the layout metadata based on the version
__weak int eeprom_layout_detect(unsigned char *data)
	- override to provide your own algorithm for detecting layout version
eeprom_field.c
	- contains various printing and updating functions for common types of
	  eeprom fields. Can be used for defining custom layouts.

ddf56bc7e3 drivers: Introduce a simplified remoteproc framework
Many System on Chip(SoC) solutions are complex with multiple processors
on the same die dedicated to either general purpose of specialized
functions. Many examples do exist in today's SoCs from various vendors.
Typical examples are micro controllers such as an ARM M3/M0 doing a
offload of specific function such as event integration or power
management or controlling camera etc.

Traditionally, the responsibility of loading up such a processor with a
firmware and communication has been with a High Level Operating
System(HLOS) such as Linux. However, there exists classes of products
where Linux would need to expect services from such a processor or the
delay of Linux and operating system being able to load up such a
firmware is unacceptable.

To address these needs, we need some minimal capability to load such a
system and ensure it is started prior to an Operating System(Linux or
any other) is started up.

NOTE: This is NOT meant to be a solve-all solution, instead, it tries to
address certain class of SoCs and products that need such a solution.

A very simple model is introduced here as part of the initial support
that supports microcontrollers with internal memory (no MMU, no
execution from external memory, or specific image format needs). This
basic framework can then (hopefully) be extensible to other complex SoC
processor support as need be.

4ea54e3f23 common/cmd_ethsw: Add generic commands for Ethernet Switches
This patch creates a flexible parser for Ethernet Switch
configurations that should support complex commands.
The parser searches for predefined keywords in the command
and calls the proper function when a match is found.
Also, the parser allows for optional keywords, such as
"port", to apply the command on a port
or on all ports. For now, the defined commands are:
ethsw [port <port_no>] { enable | disable | show }

c7ff552843 update: tftp: dfu: Extend update_tftp() function to support DFU
This code allows using DFU defined mediums for storing data received via
TFTP protocol.

It reuses and preserves functionality of legacy code at common/update.c.

The update_tftp() function now accepts parameters - namely medium device
name and its number (e.g. mmc 1).

Without this information passed old behavior is preserved.

e76cb9272d dm: tpm: Add a 'tpmtest' command
These tests come from Chrome OS code. They are not particularly tidy but can
be useful for checking that the TPM is behaving correctly. Some knowledge of
TPM operation is required to use these.

6262b72b8b dm: regulator: add regulator command
This command is based on driver model regulator's API.
The user interface provides:
- list UCLASS regulator devices
- show or [set] operating regulator device
- print constraints info
- print operating status
- print/[set] voltage value [uV] (force)
- print/[set] current value [uA]
- print/[set] operating mode id
- enable the regulator output
- disable the regulator output

The 'force' option can be used for setting the value which exceeds
the constraints min/max limits.
