mx25: fix the offset between the USB ports' registers
The USBOH module on imx25 chips contains two USB controllers which are
called USB OTG Controller and USB Host Controller. Each one has its EHCI
root hub. The OTG Controller's EHCI registers start at offset 0, the Host
Controller's registers start at offset 0x400.
We set CONFIG_MXC_USB_PORT=0 to select the OTG Controller and 1 for the
Host Controller. Therefore, IMX_USB_PORT_OFFSET must be 0x400. Using
this setting, the Host Controller starts working on my imx25 board.
Please note that the imx25 reference manual claims that the Host

Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.
The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the

Every env variable from the env to be imported passed by parameter to
this command will override the value of the variable in the current env.
If a variable exists in the current env but not in the imported env, if
this variable is passed as a parameter to env import, the variable will
be unset ONLY if the -d option is passed to env import, otherwise the
current value of the variable is kept.
If a variable exists in the imported env, the variable in the current
env will be set to the value of the one from the imported env.
All the remaining variables are left untouched.
As the size parameter of env import is positional but optional, let's
add the possibility to use the sentinel '-' for when we don't want to
give the size parameter (when the env is '\0' terminated) but we pass a
list of variables at the end of the command.
Nothing's changed for the other parameters or the overall behaviour.
One of its use case could be to load a secure environment from the
signed U-Boot binary and load only a handful of variables from an
other, unsecure, environment without completely losing control of
U-Boot.

hashtable: do not recreate whole hash table if vars are passed to himport_r
When vars are passed to the himport_r function with H_NOCLEAR flag,
those vars will be overridden in the current environment and if one of
those vars is not in the imported environment, it'll be deleted in the
current environment whatever the flag passed to himport_r.
The H_NOCLEAR flag is used to clear the whole environment whether vars
are passed to the function or not.
This leads to incoherent behaviour. If one passes vars to himport_r
with the H_NOCLEAR flag, if a var in vars is not in the imported env,
that var will be removed from the current env.
If one passes vars to himport_r without the H_NOCLEAR flag, the whole
environment will be removed and vars will be imported from the
environment in RAM.
It makes more sense to keep the variable that is in the current
environment but not in the imported environment if the H_NOCLEAR flag is
set and remove only that variable if the H_NOCLEAR flag is not set.
Let's clear the whole environment only if H_NOCLEAR and vars are not
passed to himport_r.
Let's remove variables that are in the current environment but not in
the imported env only if the H_NOCLEAR flag is not passed.

test/py: return a RAM address different from 0 as it can be interpreted as NULL
Some functions test that the given address is not NULL (0) and fail or
have a different behaviour if that's the case (e.g. hexport_r).
Let's make the RAM base address to be not zero by setting it to 2MiB if
that's the case.
2MiB is chosen because it represents the size of an ARM LPAE/v8 section.

env: add the same prefix to error messages to make it detectable by tests
The error message should start with `## Error: ` so that it's easily
detectable by tests without needing to have a complex regexp for
matching all possible error message patterns.
Let's add the `## Error: ` prefix to the error messages since it's the
one already in use.

stm32mp1: clk: support digital bypass
HSE and LSE bypass shall support both analog and digital signals.
This patch add a way to select digital bypas case in the device tree
and set the associated bit DIGBYP in RCC_BDCR and RCC_OCEN register
during clock tree initialization.
