9b33be392b net: ti: am65-cpsw-nuss: Enforce pinctrl state on the MDIO child node
The binding represents the MDIO controller as a child device tree
node of the MAC device tree node.

The U-Boot driver mostly ignores that child device tree node and just
hardcodes the resources it uses to support both the MAC and MDIO in a
single driver.

However, some resources like pinctrl muxing states are thus ignored.
This has been a problem with some device trees that will put some
pinctrl states on the MDIO device tree node, like the SK-AM62 Device
Tree does.

Let's rework the driver a bit to create a dummy MDIO driver that we will
then get during our initialization to force the core to select the right
muxing.

8faeb1d722 part: eliminate part_get_info_by_name_type()
Since commit 56670d6fb8 ("disk: part: use common api to lookup part
driver") part_get_info_by_name_type() ignores the part_type parameter
used to restrict the partition table type.

omap_mmc_get_part_size() and part_get_info_by_name() are the only
consumers.

omap_mmc_get_part_size() calls with part_type = PART_TYPE_EFI because at
the time of implementation a speed up could be gained by passing the
partition table type. After 5 years experience without this restriction
it looks safe to keep it that way.

part_get_info_by_name() uses PART_TYPE_ALL.

Move the logic of part_get_info_by_name_type() to part_get_info_by_name()
and replace the function in omap_mmc_get_part_size().

On the reboot this is shown but showing message
"Boot idx 1 is not matching active idx 0, changing active_idx"
which is changing active_idx and writing mdata to flash.

But when this message is visible it is not checking which state that images
are. If they have acceptance bit setup to yes everything is fine and valid
images are booted (doesn't mean the latest one).
But if acceptance bit is no and images are in trial state in_trial variable
is never setup. Which means that from new flashed image stable image can be
rewritten because in_trial is not setup properly.

b1aade87ca lib: sparse: allocate FASTBOOT_MAX_BLK_WRITE instead of small number
Commit 62649165cb ("lib: sparse: Make CHUNK_TYPE_RAW buffer aligned")
fixed cache alignment for systems with a D-CACHE.

However it introduced some performance regressions [1] on system
flashing huge images, such as Android.

On AM62x SK EVM, we also observe such performance penalty:
Sending sparse 'super' 1/2 (768793 KB)             OKAY [ 23.954s]
Writing 'super'                                    OKAY [ 75.926s]
Sending sparse 'super' 2/2 (629819 KB)             OKAY [ 19.641s]
Writing 'super'                                    OKAY [ 62.849s]
Finished. Total time: 182.474s

The reason for this is that we use an arbitrary small buffer
(info->blksz * 100) for transferring.

Fix it by using a bigger buffer (info->blksz * FASTBOOT_MAX_BLK_WRITE)
as suggested in the original's patch review [2].

With this patch, performance impact is mitigated:
Sending sparse 'super' 1/2 (768793 KB)             OKAY [ 23.912s]
Writing 'super'                                    OKAY [ 15.780s]

2a8ebad6ef mailbox: k3-sec-proxy: Fill non-message tx data fields with 0x0
Sec proxy data buffer is 60 bytes with the last of the registers
indicating transmission completion. This however poses a bit of a
challenge.

The backing memory for sec_proxy is regular memory, and all sec proxy
does is to trigger a burst of all 60 bytes of data over to the target
thread backing ring accelerator. It doesn't do a memory scrub when
it moves data out in the burst. When we transmit multiple messages,
remnants of previous message is also transmitted which results in
some random data being set in TISCI fields of messages that have been
expanded forward.

The entire concept of backward compatibility hinges on the fact that
the unused message fields remain 0x0 allowing for 0x0 value to be
specially considered when backward compatibility of message extension
is done.

So, instead of just writing the completion register, we continue
to fill the message buffer up with 0x0 (note: for partial message
involving completion, we already do this).

This allows us to scale and introduce ABI changes back also work with
other boot stages that may have left data in the internal memory.

While at this, drop the unused accessor function.

Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).

This implementation of the specification provides support for Aarch64.

The FF-A driver uses the SMC ABIs defined by the FF-A specification to:

    - Discover the presence of secure partitions (SPs) of interest
    - Access an SP's service through communication protocols
      (e.g: EFI MM communication protocol)

The FF-A support provides the following features:

    - Being generic by design and can be used by any Arm 64-bit platform
    - FF-A support can be compiled and used without EFI
    - Support for SMCCCv1.2 x0-x17 registers
    - Support for SMC32 calling convention
    - Support for 32-bit and 64-bit FF-A direct messaging
    - Support for FF-A MM communication (compatible with EFI boot time)
    - Enabling FF-A and MM communication in Corstone1000 platform as a use case
    - A Uclass driver providing generic FF-A methods.
    - An Arm FF-A device driver providing Arm-specific methods and
      reusing the Uclass methods.
    - A sandbox emulator for Arm FF-A, emulates the FF-A side of the
      Secure World and provides FF-A ABIs inspection methods.
    - An FF-A sandbox device driver for FF-A communication with the
      emulated Secure World.  The driver leverages the FF-A Uclass to
      establish FF-A communication.
    - Sandbox FF-A test cases.
    - A new command called armffa is provided as an example of how to
      access the FF-A bus

For more details about the FF-A support please refer to [B] and refer to [C] for
how to use the armffa command.

Please find at [D] an example of the expected boot logs when enabling
FF-A support for a platform. In this example the platform is
Corstone1000. But it can be any Arm 64-bit platform.

c7f556c7a8 arm_ffa: efi: corstone1000: enable MM communication
turn on EFI MM communication

On corstone1000 platform MM communication between u-boot
and the secure world (Optee) is done using the FF-A bus.
