a4fc6ee9e7 ARM: rmobile: Deduplicate R-Car Gen3/Gen4 reset_cpu()
The reset_cpu() implementation is basically the same across Gen3
SoCs and identical across Gen4 SoCs. Introduce weak default for
reset_cpu(), so that it does not have to be duplicated in every
board file again.

There is a slight difference for CA53 only systems, like E3 and D3,
which now check MIDR for CPU ID first just like the other systems,
but this is OK since the MIDR always returns CA53 core type and the
correct reset register is written.

000806f76b mkeficapsule: add FMP Payload Header
Current mkeficapsule tool does not provide firmware
version management. EDK II reference implementation inserts
the FMP Payload Header right before the payload.
It coutains the fw_version and lowest supported version.

This commit adds a new parameters required to generate
the FMP Payload Header for mkeficapsule tool.
 '-v' indicates the firmware version.

When mkeficapsule tool is invoked without '-v' option,
FMP Payload Header is not inserted, the behavior is same as
current implementation.

The lowest supported version included in the FMP Payload Header
is not used, the value stored in the device tree is used instead.

bfaa1fbc62 efi_loader: store firmware version into FmpState variable
Firmware version management is not implemented in the current
FMP protocol.
EDK II reference implementation capsule generation script inserts
the FMP Payload Header right before the payload, FMP Payload Header
contains the firmware version and lowest supported version.

This commit utilizes the FMP Payload Header, reads the header and
stores the firmware version into "FmpStateXXXX" EFI non-volatile variable.
XXXX indicates the image index, since FMP protocol handles multiple
image indexes.
Note that lowest supported version included in the FMP Payload Header
is not used. If the platform uses file-based EFI variable storage,
it can be tampered. The file-based EFI variable storage is not the
right place to store the lowest supported version for anti-rollback
protection.

This change is compatible with the existing FMP implementation.
This change does not mandate the FMP Payload Header.
If no FMP Payload Header is found in the capsule file, fw_version,
lowest supported version, last attempt version and last attempt
status is 0 and this is the same behavior as existing FMP
implementation.

8bfce2f998 arm: mach-k3: common: reorder removal of firewalls
K3 devices have some firewalls set up by ROM that we usually remove so
that the development is easy in HS devices.

While removing the firewalls disabling a background region before
disabling the foreground regions keeps the firewall in a state where all
the transactions will be blacklisted until all the regions are disabled.
This causes a race for some other entity trying to access that memory
region before all the firewalls are disabled and causes an exception.

Since there is no guarantee on where the background regions lie based on
ROM configurations or no guarantee if the background regions will allow
all transactions across the memory spaces, iterate the loop twice removing
the foregrounds first and then backgrounds.

de06083c88 common: dfu: Remove leading space characters
As per [1], dfu_alt_info is mentioned to be as semicolon separated
string of information on each alternate and the parsing logic in
the dfu.c is based on this.

Typically, the dfu_alt_info_* is defined in .h files as preprocessor
macros with 'alt' info separated by semicolon.

But when dfu_alt_info_* is added in the environment files(.env)
the script at "scripts/env2string.awk" converts a newline to space.
Thus adding a space character after semicolon. This results in
incorrect parsing in dfu.c which is based on the information that
'alt' info are only semicolon separated.

One option is to add dfu_alt_info_* variable in .env in single line.
But there is possiblity for it to exceed the line length limit.
So update the parsing logic to remove leading space characters
before adding to the dfu list.

899fb5aa8b cmd: sf/nand: Print and return failure when 0 length is passed
For sf commands, when '0' length is passed for erase, update, write or
read, there might be undesired results. Ideally '0' length means nothing to
do.

So print 'ERROR: Invalid size 0' and return cmd failure when length '0' is
passed to sf commands. Same thing applies for nand commands also.

Example:

ZynqMP> sf erase 0 0
ERROR: Invalid size 0
ZynqMP> sf write 10000 0 0
ERROR: Invalid size 0
ZynqMP> sf read 10000 0 0
ERROR: Invalid size 0
ZynqMP> sf update 1000 10000 0
ERROR: Invalid size 0
ZynqMP>

2f27405902 scripts/Makefile.lib: change spelling of $(srctree)/arch/$(ARCH)/dts in dtc_cpp_flags
Currently, all in-tree .dts files (apart from some under test/ and
tools/), reside in arch/$ARCH/dts. However, in the linux kernel tree,
dts files for arm64 boards, and probably in the not too distant
future [1], arm boards as well, live in subdirectories of that.

For private forks, using a vendor or project subdirectory is also more
convenient to clearly separate private code from upstream - in the
same way that code under board/ is also split and easy to maintain.

In order to prepare for us to follow suit and do the splitting of the
in-tree .dts files, and to make life a little easier for private forks
that already place dts files not directly in arch/$ARCH/dts, change
the $(srctree)/arch/$(ARCH)/dts path to instead refer to the directory of
the .dts file being compiled. This should be a no-op for all existing
cases.

719120392f arm: set alignment properly for asm funcs
ARM requires a 4-byte alignment on all ARM code (though this
requirement is relaxed to 2-byte for some THUMB code) and we
should be explicit about that here.

GAS has its own fix for this[1] that forces proper alignment
on any section containing assembled instructions, but this is
not universal: Clang's and other gaslike assemblers lack this
implicit alignment. Whether or not this is considered a bug in
those assemblers, it is better to ask directly for what we want.

7bae13da36 cli: avoid buffer overrun
Invoking the sandbox with

    /u-boot -c ⧵0xef⧵0xbf⧵0xbd

results in a segmentation fault.

Function b_getch() retrieves a character from the input stream. This
character may be > 0x7f. If type char is signed, static_get() will
return a negative number and in parse_stream() we will use that
negative number as an index for array map[] resulting in a buffer
overflow.
