The dos_partition_t struct defined in part_dos.h is nearly identical to
the struct partition defined in part_efi.h. They differ primarily in how
define their starting sector and number of sectors fields.
The former uses unsigned char arrays while the latter uses __le32 types.
Using __le32 is preferable, as it removes the ambiguity and potential
misuse of a raw byte array. This also aligns the structure with how the
Linux kernel defines it nowadays, which is the original source of it.

First set of u-boot-at91 features for the 2026.04 cycle:
This small fixes set includes fixing 64 bit builds and some warnings for
the at91 serial driver, and some cleanup on the nand driver.
The only call site of gzwrite() is cmd/unzip.c do_gzwrite(), where
the 'len' parameter passed to gzwrite(..., len, ...) function is of
type unsigned long. This usage is correct, the 'len' parameter is
an unsigned integer, and the gzwrite() function currently supports
input data 'len' of up to 4 GiB - 1 .
The function signature of gzwrite() function in both include/gzip.h
and lib/gunzip.c does however list 'len' as signed integer, which
is not correct, and ultimatelly limits the implementation to only
2 GiB input data 'len' .
Fix this, update gzwrite() function parameter 'len' data type to
size_t consistently in include/gzip.h and lib/gunzip.c .
Furthermore, update gzwrite() function 'szwritebuf' parameter in
lib/gunzip.c from 'unsigned long' to 'size_t' to be synchronized
with include/gzip.h . Rewrite the other parameters to size_t and
off_t and propagate the change too.
Since the gzwrite() function currently surely only supports input
data size of 4 GiB - 1, add input data size check. The limitation
comes from the current use of zlib z_stream .avail_in parameter,
to which the gzwrite() function sets the entire input data size,
and which is of unsigned int type, which cannot accept any number
beyond 4 GiB - 1. This limitation will be removed in future commit.

As seen by a number of patches fixing memory leaks, U-Boot has a problem
with developer expectations around devm_kmalloc and friends. Namely,
whereas in Linux these memory allocations will be freed automatically in
most cases, in U-Boot this is only true if DEVRES is enabled. Now,
intentionally, in xPL phases, we do not (and do not offer as an option)
enabling DEVRES. However in full U-Boot this is left either to the user,
or some drivers have select'd DEVRES on their own. This inconsistency is
a problem. This series goes and deals with two small issues that were
shown by having all drivers that use devm_.alloc to allocate memory also
select DEVRES and then we make DEVRES no longer be a prompted option and
instead select'd as needed. We do not make this unconditional as it
would result in growing the resulting binary on the many platforms which
have no users of the devm_.alloc family of functions.
Link: https://lore.kernel.org/r/20251227223833.3019311-1-trini@konsulko.com
The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

gardena-smart-gateway-mt7688. This is not critical at the start, but is
as we move forward. Next, we move all the way from version 9.20 of the

remove it. We also remove a number of extra text files that should be
unchanged from upstream, but provide no direct value to the project.
Instead, have the help text for LZMA note that this comes from the LZMA
SDK.
Next, we move our code up to the current release, 25.01. There are a
number of new header files, and some performance improvements made to
the code, at the cost of between 2 to 3 kilobytes in binary size. As
there is now a Kconfig option to disable this and retain similar speed
to what we have currently, the default option is to make this trade-off.

This optimization calculates the tens digit using (val * 103) >> 10, which
