e6385c7e9c Makefile: Rename ALL-y to INPUTS-y
When binman is in use, most of the targets built by the Makefile are
inputs to binman. We then need a final rule to run binman to produce the
final outputs.

Rename the variable to indicate this, and add a new 'inputs' target.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

c1c564af52 arm: mach-keystone: Use appended original image size in image processing
When an image is signed/encrypted on K2 devices the image may get padded
to meet alignment requirements for the signature/encryption type. The
original size is appended as 4 bytes little-endian to the end of the
final image.

Normally the trailing extra bytes are ignored and so restoring the
exact original size is not important. In the case of initrd the
original size is important as the kernel uses it to look for
additional filesystem data and can do the wrong thing when the
size is not correct.

Read off the original size and report it back from the image post
processing stage.

1514244cc1 ti: remove usage of DM_I2C_COMPAT and don't disable DM_I2C in SPL
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. The goal is to eventually remove DM_I2C_COMPAT

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

94f536fc4f arm: mach-keystone: Fixes issue with return values in inline assembly
The inline assembly functions in mon.c assume that the caller will
check for the return value in r0 according to regular ARM calling
conventions.

However, this assumption breaks down if the compiler inlines the
functions. The caller is then under no obligation to use r0 for the
result.

To fix this disconnect, we must explicitly move the return value
from the smc/bl call to the variable that the function returns.

1d73ce6f68 arm: mach-keystone: Updates mon_install for K2G HS
On early K2 devices (eg. K2HK) the secure ROM code does not support
loading secure code to firewall protected memory, before decrypting,
authenticating and executing it.

To load the boot monitor on these devices, it is necessary to first
authenticate and run a copy loop from non-secure memory that copies
the boot monitor behind firewall protected memory, before decrypting
and executing it.

On K2G, the secure ROM does not allow secure code executing from
unprotected memory. Further, ROM first copies the signed and encrypted
image into firewall protected memory, then decrypts, authenticates
and executes it.

As a result of this, we cannot use the copy loop for K2G. The
mon_install has to be modified to pass the address the signed and
encrypted secure boot monitor image to the authentication API.

For backward compatibility with other K2 devices and K2G GP,
the mon_install API still supports a single argument. In this case
the second argument is set to 0 by u-boot and is ignored by ROM

bcdc1c8376 keystone: k2h/e/l: Fix DMA coherency for QM PDSP
commit 1f807a9f32 ("ARM: keystone2: Refactor MSMC macros to avoid
left under a macro KS2_MSMC_SEGMENT_QM_PDSP which is no longer valid.
This, in effect disabled DMA coherency for QM PDSP.

Given that msmc_k2hkle_common_setup is valid for all K2H/K/L/E SoCs,
the #ifdef should been removed in the first place. Do the same.

e2924e5904 ARM: k2g: Configure reset mux to device reset
BOOTCFG_RSTMUX8 register controls the reset mux associated with the ARM.
Timer5(dedicated to ARM) when used as WatchDog timer, the events it
generates are routed to the above mux.

Following are the 3 events that can controlled bt the reset mux:
- Device Reset
- An interrupt to the ARM_GIC
- An interrupt to the ARM_GIC followed by a device reset.

Right now to give a default watchdog behaviour "Device reset" is
being selected.

NOTE: Few of these might have default configurations, however,
since most are software configurable, it is better to explicitly
configure the system to have a known default state.

Without programming these, we end up seeing lack of coherency on certain
peripherals resulting in inexplicable failures (such as USB peripheral's
DMA data not appearing on ARM etc and weird workarounds being done by
drivers including cache flushes which tend to have system wide
performance impact).

By marking these segments as shared, we also ensure SoC wide coherency
is enabled.
