fdtdec: optionally add property no-map to created reserved memory node
Add boolean input argument @no_map to helper function
fdtdec_add_reserved_memory() to add or not "no-map" property

Property no-map is used by the Linux kernel to not not map memory
in its static memory mapping. It is needed for example for the|
consistency of system non-cached memory and to prevent speculative
accesses to some firewalled memory.
No functional change. A later change will update to OPTEE library to
add no-map property to OP-TEE reserved memory nodes.

binman: Use target-specific tools when cross-compiling
Currently, binman always runs the compile tools like cc, objcopy, strip,
etc. using their literal name. Instead, this patch makes it use the
target-specific versions by default, derived from the tool-specific
environment variables (CC, OBJCOPY, STRIP, etc.) or from the
CROSS_COMPILE environment variable.
For example, the u-boot-elf etype directly uses 'strip'. Trying to run
the tests with 'CROSS_COMPILE=i686-linux-gnu- binman test' on an arm64
host results in the '097_elf_strip.dts' test to fail as the arm64
version of 'strip' can't understand the format of the x86 ELF file.
This also adjusts some command.Output() calls that caused test errors or
failures to use the target versions of the tools they call. After this,
patch, an arm64 host can run all tests with no errors or failures using
a correct CROSS_COMPILE value.

These test files are currently "intended for use on x86 hosts", but most
of the tests using them can still pass when cross-compiled to x86 on an
arm64 host.
This patch enables non-x86 hosts to run the tests by specifying a
cross-compiler via CROSS_COMPILE. The list of variables it sets is taken
from the top-level Makefile. It would be possible to automatically set
an x86 cross-compiler with a few blocks like:
But it wouldn't propagate to the binman process calling this Makefile,
so it's better just raise an error and expect 'binman test' to be run
with a correct CROSS_COMPILE.

binman: Build FIT image subentries with the section etype
When reading subentries of each image, the FIT entry type directly
concatenates their contents without padding them according to their

properties.
This patch makes sure these properties are respected by offloading this
image-data building to the section etype, where each subnode of the
"images" node is processed as a section. Alignments and offsets are
respective to the beginning of each image. For example, the following
fragment can end up having "u-boot-spl" start at 0x88 within the final
FIT binary, while "u-boot" would then end up starting at e.g. 0x20088.
fit {
description = "example";

The bitflip test uses two equal sized memory buffers. This is achieved
by splitting the range of memory into two pieces. The address of the
second buffer, as well as the length of each buffer, were not correctly
calculated. This caused bitflip test to access beyond the end of range.
This patch fixes the pointer arithmetic problem.
A second problem arises because u-boot "mtest" command expects the
ending address to be inclusive. When computing (end - start) this
results in missing 1 byte of the requested length. The bitflip test
expects a count rather than an "ending" address. Thus it fails to test
the last word of the requested range. Fixed by using (end - start + 1).
Added Kconfig option to optionally disable the bitflip test, since it
does add significantly to the time taken for "mtest".
