824705d53c mx6cuboxi: Add emmc device tree suffix
Mainline and now the SolidRun 4.9 nxp based tree use the new
reorganization of device-tree files that separate out the emmc
into its own dtb.  u-boot will now look for -emmc in the device
tree name if one is detected.

19ed6063a5 mx6cuboxi: Use mmc_get_op_cond() to check for an eMMC
Previously we had just made broad assumptions with which of our
boards had an eMMC or not even though this is a manufacturing time
assembly option.  This takes the guessing away and actually checks for
the existence of an eMMC and sets up the has_emmc environment variable.

315ded9730 rockchip: veyron: Set vcc33_sd regulator value
On the veyron board the vcc33_sd regulator is used as vmmc-supply for
the SD card. This regulator is powered in the MMC core during power on
but its value is never actually set.

In the veyron platform the reset value for the LDO output is 1.8V while
the standard (min and max) value for this regulator defined in the DTS
is 3.3V. When the MMC core enable the regulator without setting its
value, the output is automatically set to 1.8V instead of 3.3V.

With this patch we preemptively set the value to 3.3V.

de5dd4c4e3 spl: record boot_device into spl_image and call spl_perform_fixups
On some boards, we want to give the board/architecture-specific code a
chance to look at where the next image has been loaded from and
perform fixups before starting the next image.  This is of particular
importance, when we probe multiple devices for bootable payloads and
boot the first one found.

This change adds the following:
 - we record the boot_device used into the spl_image structure
 - we provide an extension-point for boards/architectures that can
   perform late fixups depending on a fully populated spl_image
   structure (i.e. we'll know the final boot_device and have info
   on the image type and operating system to be booted).

For each variable passed as parameter, if
 - foo is bar in current env and bar2 in exported env, after importing
 exported env, foo shall be bar2,
 - foo does not exist in current env and foo is bar2 in exported env,
 after importing exported env, foo shall be bar2,
 - foo is bar in current env and does not exist in exported env (but is
 passed as parameter), after importing exported env, foo shall be empty
 ONLY if the -d option is passed to env import, otherwise foo shall be
 bar,

Any variable not passed as parameter should be left untouched.

Two other tests are made to test that size cannot be '-' if the checksum
protection is enabled.

eaf734724f cmd: nvedit: env import can now import only variables passed as parameters
While the `env export` can take as parameters variables to be exported,
`env import` does not have such a mechanism of variable selection.

Let's add the ability to add parameters at the end of the command for
variables to be imported.

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.

env import addr
env import addr -
env import addr size
env import addr - foo1 foo2
env import addr size foo1 foo2

are all valid.

env import -c addr
env import -c addr -
env import -c addr - foo1 foo2

are all invalid because they don't pass the size parameter required for
checking, while the following are valid.

env import addr size
env import addr size foo1 foo2

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.

d9fc9077eb 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.
