There's an issue with the base board in which the power cycle
circuit takes way longer to power down than expected by mmc core.
code. This prevents the card from enumerating in UHS modes.
Disable UHS modes for this board until a new board revision fixes
the issue.

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

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.

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.

DLL need only be enabled for speed modes and clock frequencies at or

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.

The K3 R5F remoteproc driver in U-Boot was upstreamed prior to the

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

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

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:

5 .bss 00000060 fef5baa0 fef5baa0 00000000 2**5
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.
