The IMX28 PMU (Power Management Unit) has a dedicated Linear Regulator
to produce (by default) 4.2V output - available outside the chip as
VDD_4P2.
When system is supposed to not use VDD5V as a main power source - instead
the DCDC_BATT is used; it is safe to disable this regulator.
As the in-PMU DCDC switching regulator (from which DCDC_VDDA, DCDC_VDDIO
and DCDC_VDDD are generated) can be driven from DCDC_BATT or output
of this 4P2 regulator - by disabling the latter the use of the DCDC_BATT
is forced.
To be more specific - according to NXP's AN4199 the DCDC_BATT source is
preferred (over VDD5V), as more efficient and stable source for
industrial applications.

This new Kconfig option allows disabling the in-PMU battery charging
block. This may be required when DCDC_BAT source is powered not from
battery, but from already regulated, good quality source.

This option sets the current limit for 5V source to zero, so all
the PMU outputs are primarily powered from battery source (DCDC_BAT).
This option may be set on systems, where the 5V is NOT supposed to be
in any scenario powering the system - for example on systems where
DCDC_BAT is connected to fixed and regulated 4.2V source (so the
"battery" is not present).

In the imx8m power domain kernel driver, there is an extra udelay(5)
prior to requesting the domain to power up:

Haven't observed any issues due to the lack of this delay in U-Boot yet,

The update_firmware script is intended to update the boot firmware but

Specifically:
- IMX8MM/IMX8MP (BOOTROM v2) the offset is 32KiB for SD and eMMC user
hardware partition and 0KiB for eMMC boot partitions.
- IMX8MM the offset is 33KiB for SD and eMMC regardless of hardware

Double the default variable store size so the variables fit. There is a

EFI variable by subtracting the occupied buffer size and the overhead
for a new variable from the maximum buffer size set in Kconfig. This
is then returned as QueryVariableInfo()'s RemainingVariableStorageSize
output.
This can underflow as the calculation is done in and processed as
unsigned integer types. Check for underflow before doing the subtraction
and return zero if there's no space.

Docs describe 'make clean' to delete most generated files, 'make

test tries to assert it.
Idea is to search remaining files by patterns in copies of the initial
out-of-source build, which has two advantages:
- looking in an out-of-source build dir allows to tell generated source
code from committed source code
- copying is fast (compared to rebuilding each time) which allows to do

On 'make clean', generated C files in tools/env/ and tools/boot/ are
currently not removed, but they should.
Auto-generation for shared sources was first introduced with
ad80c4a322 ("kbuild, tools: generate wrapper C sources automatically
by Makefile"). Cleanup later regressed (see Fixes:), because shared
files were moved out of lib/ and common/, but 'clean-dirs := lib common'
was not adjusted accordingly. Further, the generated
tools/env/embedded.c became a sibling to project files, which prevents
directory-wise cleanup at all.
To solve it, we establishe tools/generated/ as the sole place for
generated sources. Wrappers are now generated as
tools/generated/<orig_dirname>/<orig_filename>, and 'make clean' can
remove tools/generated/ as a whole (Linux Makefile.asm-generic headers
are cleaned similarly). This way we don't have to maintain separate
clean-files or clean-dirs entries for each single added or moved wrapper
file.
