26839e5dde cmd: SCP03: enable and provision command
Enable and provision the SCP03 keys on a TEE controlled secured elemt
from the U-Boot shell.

Executing this command will generate and program new SCP03 encryption
keys on the secure element NVM.

Depending on the TEE implementation, the keys would then be stored in
some persistent storage or better derived from some platform secret
(so they can't be lost).

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;
    type argtype;
    @@
    - reset_cpu(argtype argname)
    + reset_cpu(void)
    { ... }

da7991b38e cmd: pwm: Rework argc sanity checking
Currently, we check argc in a number of places to make sure that we have
all of the required arguments for each of the pwm sub-commands.
However, there's at least one place where we've got dead code as we'll
never have argc == 0, due to checking that argc was at least 4 earlier
and having only subtracted 3.  Rework things so that when we have
determined our subcommand make sure we have the right number of
arguments for it, or error out.  This means we can stop checking against
argc again later.

2147a16983 dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIO
Use CONFIG_IS_ENABLED() macro, which provides more convenient
way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs
for both SPL and U-Boot proper.

CONFIG_IS_ENABLED(DM_I2C) expands to:
- 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y',
- 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y',
- 0 otherwise.

All occurences were replaced automatically using these bash cmds:
$ find . -type f -exec sed -i
     's/ifndef CONFIG_DM_I2C/if !CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i

For now no callers pass the size, but this can be updated later.

Also adjust the return value to an error code so that all the different

bafdf4caac cmd: bcb: Add support for processing const string literals in bcb_set()
On request/suggestion from Simon Glass back in May 22 2019 [1], the
'strsep' mechanism implemented in bcb_set() was set to work directly
with user-provided argv strings, to avoid duplicating memory and for
the sake of simpler implementation.

However, since we recently exposed bcb_write_reboot_reason() API to be
called by U-Boot fastboot, the idea is to be able to pass const string
literals to this new BCB API, carrying the reboot reason.

Since 'strsep' (just like its older/superseded sibling 'strtok')
modifies the input string passed as parameter, BCB command in its
current state would attempt to perform in-place modifications in a
readonly string, which might lead to unexpected results.

Fix the above with the cost of one dynamic memory allocation ('strdup').
This will also ensure no compiler warnings when passing string literals
to bcb_write_reboot_reason().

e74670adfe cmd: bcb: Expose 'bcb_write_reboot_reason' to external callers
Fastboot is evolving and beginning with commit [1], the
upstream implementation expects bootloaders to offer support for:
 - reboot-recovery
 - reboot-fastboot

The most natural way to achieve the above is through a set of
pre-defined "reboot reason" strings, written into / read from
the BCB "command" field, e.g.:
 - bootonce-bootloader [2]
 - boot-fastboot [3]
 - boot-recovery [4]

Expose the first 'bcb' API meant to be called by e.g. fastboot stack,
to allow updating the BCB reboot reason via the BCB 'command' field.

e2ffb3be49 cmd: bcb: Extract '__bcb_store' from 'do_bcb_store' for internal needs
Enriching the functionality of U-Boot 'bcb' may assume using the
existing sub-commands as building blocks for the next ones.

A clean way to achive the above is to expose a number of static
routines, each mapped to an existing user command (e.g. load/set/store),
with a user/caller-friendly prototype (i.e. do not force the caller
to wrap an integer into a string).

This third patch makes '__bcb_store' available for internal needs.

No functional change intended.

82d01f04fa efi_loader: switch to non-secure mode later
Some ARMv7 boards using PSCI require to be in secure-mode when booted via
'bootz' or 'bootm'. During distro-boot 'bootefi bootmgr' is called to check
if booting via UEFI is possible.

With the change we change the switch from secure mode to non-secure mode is
moved from the UEFI subsystem setup to just before calling StartImage().

69076dff22 cmd: pxe: add support for FDT overlays
This adds support for specifying FDT overlays in an extlinux/pxelinux
configuration file.

Without this, there is no simple way to apply overlays when the kernel
and fdt is loaded by the pxe command.

This change adds the 'fdtoverlays' keyword for a label, supporting multiple
overlay files to be applied on top of the fdt specified in the 'fdt' or
'devicetree' keyword.

Example:
  label linux
    kernel /Image
    fdt /soc-board.dtb
    fdtoverlays /soc-board-function.dtbo
    append console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait

This code makes usage of a new variable called fdtoverlay_addr_r used to load
the overlay files without overwritting anything important.
