The CPSW3G instance of CPSW on AM62PX SoC provides Ethernet functionality.
Currently, Ethernet is supported on Linux which runs on the A53 core on the
SoC, by allocating all of the DMA resources associated with CPSW to A53_2.
In order to enable use-cases where the Ethernet traffic is sent from or
consumed by various CPU cores on the SoC simultaneously, while at the
same time, maintaining backward compatibility with the existing use-case
of A53 being the sole entity that exchanges traffic with CPSW via DMA,
update the DMA resource sharing scheme on AM62PX SoC to the following:
--------------- -------------- ------------- ----------------
Resource WKUP_R5 MCU_R5 A53_2
--------------- -------------- ------------- ----------------
TX Channels [8] => 4 (Primary) 4 (Primary) 8 (Secondary)
TX Rings [64] => 32 (Primary) 32 (Primary) 64 (Secondary)
RX Channels [1] => 1 (Primary) 0 1 (Secondary)
RX Flows [16] => 6 (Primary) 10 (Primary) 16 (Secondary)
In the absence of primary owners of resources (existing use-case
where A53 owns all of the CPSW DMA resources), the secondary owner
can claim all of the resources as its own. For shared use-cases,
the resources that are not claimed by the primary are communicated
to the secondary owner allowing it to claim them. This ensures that
Linux on A53_2 can continue claiming all DMA resources associated
with CPSW in the absence of primary owners, while at the same time
providing users the flexibility to share CPSW DMA resources across
various CPU cores listed above if needed.
While Linux has been mentioned as the Operating System running
on A53, there is no dependency between the Operating System
running on A53 and its ability to claim the CPSW DMA resources
listed above.

Some K3 devices like am62x and am64x have a M4 processor in the MCU
voltage domain. This patch series introduces remoteproc M4 driver which
will be used to load firmware into and start the M4 remote core.
This series also adds support for R5F cores on am64x SoCs in patch 2 and
sets up environment to load FW in remote cores in patch 3,4,5.
This patch series also enables remoteproc drivers by default as per what
remoteproc sybsystem is supported per SoC, thus all remoteproc options
are now deleted in configs/* since they are no longer required.
This patch series was tested on am64x EVM, am62x SK, am62ax SK,
am62px SK boards.
Any additional tested by's are welcome since I was not able to
test any additional boards.
Tested by running the following commands in u-boot prompt:
=> setenv dorprocboot 1
=> run boot_rprocs

files, remove these configs which are no longer needed to be
defined here in configs/.

Add CONFIG_BOOTCOUNT_ALTBOOTCMD so the developer is able to add
custom altbootcmd via Kconfig when they enable BOOTCOUNT. With this now
in Kconfig, we need to move it from environment files / config.h files
and in to the defconfig file.
This was done by generating u-boot-initial-env for all platforms before
the Kconfig change, to extract altbootcmd values and then again after to
compare the result.

This series completes the removal of test commands for suites. With this
it is possible to declare a suite (including init and uninit functions)
without needing to write a command.
It also adds timing for test suites, so we can keep track of how long
things take.

At present the 'ut' command handles its flags in a strange way, in that
they must come after the subcommand.
So, we must use 'ut bloblist -r2' to run the bloblist tests twice. This
is an artefact of the way tests were run, through subcommands.
It is now possible to correct this, by doing flag-processing before
running the suite.
Update the code to handle this, so that 'ut -r2 bloblist' works. Update
the 'test_suite' test to check the new arguments.
Add a sanity-check for -I while we are here.
