There was no "mcheck" for U-Boot before.
Since U-Boot has only 1 thread, and normally makes 4000+ - 6000+

My variant uses 2x8 = 16byte-long protector. And
the multiplier could be changed to tune speed/protection tradeoff.
This protects not only against memset()-s, but against "near" wild
pointers too, and makes more probable to catch "distant" ones.
The core file of the set is included into the C-file, not complied
separately in order to enable (potential) coexisting of
mcheck-protectors, e.g. malloc_simple(.) and dlmalloc simultaneously.
My tests were for ARM SoC, 64bit, so the patch is

if a change doesn't break the heap integrity.

This series has been tested on AM65x SR2.0, and the ICSSG interface is

To use ICSSG2 ethernet, the ICSSG firmware needs to be loaded to PRU RPROC

The remoteproc driver uses request_fw_into_buf() API from fs-loader driver

zlib_inflate: Upgrade library code to a recent version") which described
ZLIB_VERSION removal as
"This patch also removes ZLIB_VERSION as it no longer has a correct value.
We don't need version checks anyway as the kernel's module handling will
take care of that for us. This removal is also more in keeping with the
zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've
added something to the zlib.h header to note its a modified version."
Author describes wish to follow this guidance at
https://www.zlib.net/zlib_faq.html#faq24:
"The license says that altered source versions must be "plainly marked". So
what exactly do I need to do to meet that requirement?
You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
particular, the final version number needs to be changed to f, and an
identification string should be appended to ZLIB_VERSION. Version numbers
x.x.x.f are reserved for modifications to zlib by others than the zlib
maintainers. For example, if the version of the base zlib you are altering
is 1.2.3.4, then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
ZLIB_VERSION to something like 1.2.3.f-zachary-mods-v3. You can also update
the version strings in deflate.c and inftrees.c."

has been used by Linux kernel where ZLIB_VERSION is completely removed.

by these config options, however this script currently isn't being run.
Calling this script results in the correct device tree being retrieved:
Retrieving file: /dtbs/6.8.1+/ti/k3-am625-sk.dtb
Many boards are calling this script as part of their boot command. The
am62x currently isn't. Rectify this so that booting works correctly.

arm: mach-k3: am625: Fixup a53 cpu frequency by speed grade
The maximum frequency of the A53 CPU on the AM62 depends on the speed
grade of the SoC. However, this value is hardcoded in the DT for all
AM62 variants, potentially causing specifications to be exceeded. Moreover,
setting a common lower frequency for all variants increases boot time.
To prevent these issues, modify the DT at runtime from the R5 core to
adjust the A53 CPU frequency based on its speed grade.

arm: mach-k3: am62: Get a53 max cpu frequency by speed grade
AM62 SoC has multiple speed grades. Add function to return max A53 CPU
frequency based on grade. Fastest grade's max frequency also depends on
PMIC voltage, to simplify implementation use the smaller value.

boot: fdt: Change type of env_get_bootm_low() to phys_addr_t
Change type of ulong env_get_bootm_low() to phys_addr_t env_get_bootm_low().
The PPC/LS systems already treat env_get_bootm_low() result as phys_addr_t,
while the function itself still returns ulong. This is potentially dangerous
on 64bit systems, where ulong might not be large enough to hold the content
of "bootm_low" environment variable. Fix it by using phys_addr_t, similar to
what env_get_bootm_size() does, which returns phys_size_t .

This series is the culmanation of the current line of refactoring

With this is is possible to boot using the extlinux bootmeth without
