There's an issue with the base board in which the power cycle

2121c7e2d5 arm: dts: k3-am65: Fix mmc nodes
Because of fundamental interface issues in am65x pg1, only the
initial sdhci1 node at 25 MHz was added in the u-boot.dtsi
from which both the base-board.dts and r5-base-board.dts
inherit the node. Move the node out to k3-am65-main.dtsi
where it belongs and add the board specific properties
in base-board.dts and r5-base-board.dts

This ensures dts compatibility with the kernel dts in the
base-board.dts and enables the SD card interface at 50 MHz
and High Speed mode

While we are here, also fix the main_mmc0_pins_default
property to be included and inherit from the base-board.dts
instead of the u-boot.dtsi

27a87c834f mmc: am654_sdhci: Fix HISPD bit configuration in some lower speed modes
According to the AM654x Data Manual[1], the setup timing in lower speed
modes can only be met if the controller uses a falling edge data launch.

To ensure this, the HIGH_SPEED_ENA (HOST_CONTROL[2]) bit should be
cleared in default speed, SD high speed, MMC high speed, SDR12 and SDR25
speed modes.

Use the sdhci writeb callback to implement this condition.

a759abf569 mmc: am654_sdhci: Add support for software tuning
With the new SW tuning App note[1], a custom tuning algorithm is
required for eMMC HS200, HS400 and SD card UHS modes. The algorithm
involves running through the 32 possible input tap delay values and
sending the appropriate tuning command (CMD19/21) for each of them
to get a fail or pass result for each of the values. Typically, the
range will have a small contiguous failing window. Considering the
tuning range as a circular buffer, the algorithm then sets a final
tuned value directly opposite to the failing window.

c964447ea3 mmc: am654_sdhci: Add support for input tap delay
DLL need only be enabled for speed modes and clock frequencies at or
above 50 MHz. For speed modes that don't enable the DLL, we need to
configure a static input delay value. This involves reading an optional
itap-del-sel-* value from the device tree and configuring it for the
appropriate speed mode.

Therefore, move all dll configurations to their own functions and gate it
with 50 MHz speed and a minimum mode. If both these conditions are not
satisfied then configure delay chain modes.

468ec2f3ef remoteproc: k3_r5: Sync to upstreamed kernel DT property names
The K3 R5F remoteproc driver in U-Boot was upstreamed prior to the
equivalent remoteproc driver in the Linux kernel. Some of the DT
properties used in U-Boot got upstreamed using different names
in Linux kernel.

The modified property names include the R5F cluster mode configuration
property "lockstep-mode"; and three different individual R5F core config
properties - "atcm-enable", "btcm-enable" and "loczrama". The property
names were updated as follows:
  lockstep-mode => ti,cluster-mode
  atcm-enable   => ti,atcm-enable
  btcm-enable   => ti,btcm-enable
  loczrama      => ti,loczrama

Update the K3 R5F remoteproc driver, the corresponding binding, and
all the existing usage in AM65x, J721E and J7200 dts files all at
once to use the new properties and to not break any bisectability.

372497572b test/py: fix runtest wrapper for pytest 6
The implementation of pytest_runtest_protocol() must call
pytest_runtest_logstart() and pytest_runtest_logfinish(). This appears to
be necessary even in pytest 5.2.1 judging by the default version of
pytest_runtest_protocol(), but evidently some form of code reorganization
in pytest only made this have a practical effect in the newer version. I'd
previously been under the impression that 100% of the required work of
pytest_runtest_protocol() was handled by the fact it called
runtestprotocol() as its implementation. However, it appears that custom
implementations do need to do a little more than this.

37c664e825 x86: Make sure the SPL image ends on a suitable boundary
The part of U-Boot that actually ends up in u-boot-nodtb.bin is not built
with any particular alignment. It ends at the start of the BSS section.
The BSS section selects its own alignment, which may larger.
This means that there can be a gap of a few bytes between the image
ending and BSS starting.

Since u-boot.bin is build by joining u-boot-nodtb.bin and u-boot.dtb (with
perhaps some padding for BSS), the expected result is not obtained. U-Boot
uses the end of BSS to find the devicetree, so this means that it cannot
be found.

Add 32-byte alignment of BSS so that the image size is correct and
appending the devicetree will place it at the end of BSS.

Example SPL output without this patch:

Sections:
Idx Name          Size      VMA       LMA       File off  Algn

                  ALLOC

You can see that .bss is aligned to 2**5 (32 bytes). This is because of
the mallinfo struct in dlmalloc.c:

 17 .bss.current_mallinfo 00000028  00000000  00000000  000004c0  2**5
                  ALLOC

In this case the size of u-boot-spl-nodtb.bin is 0x1ba90. This matches up
with the _image_binary_end symbol:

fef5ba90 g       .binman_sym_table      00000000 _image_binary_end

But BSS starts 16 bytes later, at 0xfef5baa0, due to the 32-byte
alignment. So we must align _image_binary_end to a 32-byte boundary. This
forces the binary size to be 0x1baa0, i.e. ending at the start of bss, as
expected.

Note that gcc reports __BIGGEST_ALIGNMENT__ of 16 on this build, even
though it generates an object file with a member that requests 32-byte
alignment.

The current_mallinfo struct is 40 bytes in size. Increasing the struct to
68 bytes (i.e. just above a 64-byte boundary) does not cause the alignment
to go above 32 bytes. So it seems that 32 bytes is the maximum alignment
at present.
