13e28f4987 configs: Remove a number of unreferenced CONFIG options.
There are a large number of options under CONFIG_SYS (but some of these
are elsewhere, spotted while cleaning CONFIG_SYS) that are never
referenced, or only used slightly later in the config file.  Remove or
restructure these.

17ead040d4 Audit <flash.h> inclusion
A large number of files include <flash.h> as it used to be how various
SPI flash related functions were found, or for other reasons entirely.
In order to migrate some further CONFIG symbols to Kconfig we need to
not include flash.h in cases where we don't have a NOR flash of some
sort enabled.  Furthermore, in cases where we are in common code and it
doesn't make sense to try and further refactor the code itself in to new
files we need to guard this inclusion.

b661c1bc92 arm: mach-k3: security: Remove certificate if detected on GP device
If the device is a GP and we detect a signing certificate then remove it.
It would fail to authenticate otherwise as the device is GP and has no
secure authentication services in SYSFW.

This shouldn't happen often as trying to boot signed images on GP devices
doesn't make much sense, but if we run into a signed image we should at
least try to ignore the certificate and boot the image anyway. This could
help with users of GP devices who only have HS images available.

If this does happen, print a nice big warning.

bf28d9a659 spl: mmc: Use correct MMC device when loading image
When attempting to load images from multiple MMC devices in sequence,
spl_mmc_load() chooses the wrong device from the second attempt onwards.

The reason is that MMC initialization is only done on its first call and
spl_mmc_load() will then continue using this same device for all future
calls.

Fix this by checking the devnum of the "cached" device struct against
the one which is requested.  If they match, use the cached one but if
they do not match, initialize the new device.

This fixes specifying multiple MMC devices in the SPL's boot order to
fall back when U-Boot Proper is corrupted or missing on the first
attempted MMC device.

by absense of console event channel, that is not available when console
config is disabled. Now console related code will be removed when
Xen HVC is turned off.

53d2ab9b5a doc: develop: Describe system configuration
Start by describing in general the best practices for how to implement
configuration of some aspect of U-Boot.  This generally means finding
the right choices for when something should be static or dynamically
configured and enabled.  Then further document when to use CONFIG or CFG
namespaces for static configuration.

bf89358b4c doc: environment: Further expand on Image locations and provide example
Start by elaborating on what some of our constraints tend to be with
image location values, and document where these external constraints
can come from.  Provide a new subsection, an example based on the TI
ARMv7 OMAP2PLUS families of chips, that gives sample values and explains
why we use these particular values.  This is based on what is in
include/configs/ti_armv7_common.h as of fb3ad9bd92 ("TI: Add, use a
DEFAULT_LINUX_BOOT_ENV environment string") as this contains just the
values referenced in this document now and not some of the further
additions that are less generic.

b2d7619e46 arm: mvebu: turris_omnia: Fix mpp26 pin name and comment
There is a bug in Turris Omnia's schematics, whereupon the MPP[26] pin,
which is routed to CN11 pin header, is documented as SPI CS1, but
MPP[26] pin does not support this function. Instead it controls chip
select 2 if in "spi0" mode.

Fix the name of the pin node in pinctrl node and fix the comment in SPI
node.
