2dc16a2c1f Bump LMB_MAX_REGIONS default to 16
Since commit 06d514d77c ("lmb: consider EFI memory map") the EFI regions
are also pushed into the lmb if EFI_LOADER is enabled (which is by
default on most system). Which can cause the number of entries to go
over the maximum as it's default is only 8.

Specifically i ran into this case on an TI am62 which has an fdt with
4 reserved regions (in practice 3 lmb entries due to adjecent ranges).

As this is likely to impact more devices bump the default max
regions to 16 so there is a bit more slack.

c5279ea1c3 lmb: Set correct lmb flags for EFI memory map entries
When adding reserved memory areas from the EFI memory map set the NOMAP
flag when applicable. When this isn't done adding "no-map" flagged entries
from the fdt after receiving the same from the EFI memory map fails due

007ae5d108 lmb: Default to not-LMB_USE_MAX_REGIONS
The LMB code allows for picking a hard limit on the number of regions it
can know of, or to dynamically allocate these regions. The reason for
this choice is to allow for the compiler to perform a size optimization
in the common case. This optimization however, is very small, ranging
from 196 bytes to 15 bytes saved, or in some cases, being larger. Now
that we also have more regions covered by LMB (in order to protect
various parts of our self at run time), the default of 8 is also much
easier to hit and leads to non-obvious error messages (which imply that
an area is protected, not that we're out of areas to add to the list).

Switch to the dynamic use as the default.

7f33194132 lib: Support printing an error string
It is often useful to show an error code to give the user a clue as to
what went wrong. When error strings are compiled into U-Boot it is
possible to show a message as well.

But at present it is not very convenient, since code must check if the
error strings are present, then obtain the error string and use it in
a printf() string.

Add a %dE option which shows an error code along with an error string,
if available. This makes it easy to show one or both.

4b9b25d943 lib: zstd: update to latest Linux zstd 1.5.2
Update the zstd implementation to match Linux zstd 1.5.2 from commit
2aa14b1ab2.

This was motivated by running into decompression corruption issues when
trying to uncompress files compressed with newer versions of zstd. zstd
users also claim significantly improved decompression times with newer
zstd versions which is a side benefit.

Original zstd code was copied from Linux commit 2aa14b1ab2 which is a
custom-built implementation based on zstd 1.3.1. Linux switched to an
implementation that is a copy of the upstream zstd code in Linux commit
e0c1b49f5b, this results in a large code diff. However this should make
future updates easier along with other benefits[1].

This commit is a straight mirror of the Linux zstd code, except to:
- update a few #include that do not translate cleanly
  - linux/swab.h -> asm/byteorder.h
  - linux/limits.h -> linux/kernel.h
  - linux/module.h -> linux/compat.h
- remove assert() from debug.h so it doesn't conflict with u-boot's
  assert()
- strip out the compressor code as was done in the previous u-boot zstd
- update existing zstd users to the new Linux zstd API
- change the #define for MEM_STATIC to use INLINE_KEYWORD for codesize
- add a new KConfig option that sets zstd build options to minify code
  based on zstd's ZSTD_LIB_MINIFY[2].

These changes were tested by booting a zstd 1.5.2 compressed kernel inside a
FIT. And the squashfs changes by loading a file from zstd compressed squashfs
with sqfsload. buildman was used to compile test other boards and check for
binary bloat, as follows:

> $ buildman -b zstd2 --boards dh_imx6,m53menlo,mvebu_espressobin-88f3720,sandbox,sandbox64,stm32mp15_dhcom_basic,stm32mp15_dhcor_basic,turris_mox,turris_omnia -sS

448e2b6327 event: Correct dependencies on the EVENT framework
The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

ea3d28ec31 Revert "time: add weak annotation to timer_read_counter declaration"
This reverts commit 65ba7add0d.

A weak extern is a nasty sight to behold: If the symbol is never
defined, on ARM, the linker will replace the function call with a NOP.
This behavior isn't well documented but there are at least some hints
to it [1].

When timer_read_counter() is not defined, this obviously does the wrong
thing here and it does so silently.  The consequence is that a board
without timer_read_counter() will sleep for random amounts and generally
have erratic get_ticks() values.

Drop the __weak annotation of the extern so a linker error is raised
when timer_read_counter() is not defined.  This is okay, the original
reason for the reverted change - breaking the sandbox build - no longer
applies.

Final sidenote:  This was the only weak extern in the entire tree at
this time as far as I can tell.  I guess we should avoid introduction of
them again as they are obviously a very big footgun.

77bb14758d efi_loader: avoid adding variables twice
When the efi subsystem starts we restore variables that are both in a
file or stored into the .efi_runtime section of U-Boot.  However once
a variable gets created or changed the preseeded entries will end up in
the file.  As a consequence on the next boot we will end up adding
identical variable entries twice.

Fix this by checking if the to be inserted variable already exists.
Also swap the restoration order and start with the file instead of the
builtin variables,  so a user can replace the preseeded ones if needed.

* Get the boot index passed to U-Boot by the prior stage bootloader
  and use this value for metadata bookkeeping.
* Check if the system is booting in Trial State. If the system boots
  in the Trial State for more than a specified number of boot counts,
  change the Active Bank to be booting the platform from.

Call these checks through the main loop event at the time of platform
boot.

7d6e2c54b7 FWU: Add helper functions for accessing FWU metadata
Add weak functions for getting the update index value and dfu
alternate number needed for FWU Multi Bank update
functionality.

The current implementation for getting the update index value is for
platforms with 2 banks. If a platform supports more than 2 banks, it
can implement it's own function. The function to get the dfu alternate
number has been added for platforms with GPT partitioned storage
devices. Platforms with other storage partition scheme need to
implement their own function.

2eaedc9516 FWU: Add FWU metadata structure and driver for accessing metadata
In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, which is stored on
a dedicated partition. Add the metadata structure, and a driver model
uclass which provides functions to access the metadata. These are
generic API's, and implementations can be added based on parameters
like how the metadata partition is accessed and what type of storage
device houses the metadata.

fb63362c63 lib: fix buggy strcmp and strncmp
There are two problems with both strcmp and strncmp:

(1) The C standard is clear that the contents should be compared as
"unsigned char":

  The sign of a nonzero value returned by the comparison functions
  memcmp, strcmp, and strncmp is determined by the sign of the
  difference between the values of the first pair of characters (both
  interpreted as unsigned char) that differ in the objects being
  compared.

(2) The difference between two char (or unsigned char) values can
range from -255 to +255; so that's (due to integer promotion) the
range of values we could get in the *cs-*ct expressions, but when that
is then shoe-horned into an 8-bit quantity the sign may of course
change.

The impact is somewhat limited by the way these functions
are used in practice:

- Most of the time, one is only interested in equality (or for
  strncmp, "starts with"), and the existing functions do correctly
  return 0 if and only if the strings are equal [for strncmp, up to
  the given bound].

- Also most of the time, the strings being compared only consist of
  ASCII characters, i.e. have values in the range [0, 127], and in
  that case it doesn't matter if they are interpreted as signed or
  unsigned char, and the possible difference range is bounded to
  [-127, 127] which does fit the signed char.

For size, one could implement strcmp() in terms of strncmp() - just
make it "return strncmp(a, b, (size_t)-1);". However, performance of
strcmp() does matter somewhat, since it is used all over when parsing
and matching DT nodes and properties, so let's find some other place
to save those ~30 bytes.

c726fc01cf dm: treewide: Use uclass_first_device_err when accessing one device
There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.

Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.

Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.

Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

Loadfile2 code is installing two protocols on it's own handle
and uses efi_delete_handle() to clean it up on failure(s). However
commit 05c4c9e21a ("efi_loader: define internal implementations of

efi_delete_handle() used in favor of Install/UninstallMultipleProtocol.

While at it clean up the non needed void casts to (void *) on the
