Merge patch series "Add support for K3 BIST"
Neha Malcom Francis <n-francis@ti.com> says:
This series implements a driver for the BIST (Built-In Self Test) module
for K3 devices. The BIST driver must ideally support triggering of BIST
tests, both PBIST (Memory BIST) and LBIST (Logic BIST) on a core. Both
tests are destructive in nature. Please see links [1] and [2] for
further information regarding the two.
At boot up, BIST is executed by hardware for the MCU domain
automatically as part of HW POST. So BIST has been checked only for the
MCU domain when U-Boot comes up in the usual U-Boot to Linux boot flow.
To facilitate the use-case where some safe firmware is intended to be
run on a safe core, it is best to have triggered the BIST tests on that
core. As an example, we take triggering the BIST tests on the MAIN R52_x
cores. The triggering patch is kept as DONOTMERGE.
The general procedure for triggering BIST on a core is:
1. Power on the core under test following a sequence
2. Trigger the BIST test
3. Reset the core under test following a sequence
BIST tests are triggered from A72 SPL where the DM (Device Manager
firmware that handles power management) is already up and can perform
these power sequences for us.

This is a fix for the sporadic mmc write failure:
mmc write failed
0 blocks written: ERROR
After this happens the emmc will remain in an error state
where subsequent read/writes fail with a timeout.
The mmc driver sends CMD25 - WRITE_MULTIPLE_BLOCK which
can sporadically timeout. When this happens, the mmc driver
aborts the transfer and returns the above error messages.
But the emmc still remains in data transfer mode, since
the timeout was decided by uboot, not by the emmc.
Fix this by sending the STOP_TRANSMISSION command (CMD12)
and waiting for the emmc to be in ready state again (CMD13).
Transferring data blocks after a CMD25 can take anywhere
between 5 and +15s on Samsung EMMCs and the current timeout
is not enough. Increase the timeout by 2x to accommodate the
long transfer times observed.

Recent changes to mkimage introduced a validation step to ensure that

This patch adds a Python test case to verify that mkimage correctly

a minimal ITS with an invalid default reference and checks that mkimage
produces the expected error message.
tools: fit_image: validate existence of default configuration node
When a FIT image declares a default configuration via the
'configurations/default' property, it must reference a valid subnode
under the /configurations node. If the named default does not exist,
U-Boot will fail to boot the image when no explicit configuration is
provided.
This patch adds a validation step in mkimage to check that the
referenced default configuration node is present. If not, mkimage will
print an error and abort.
This helps catch malformed or outdated ITS files early at build time
instead of deferring failure to runtime.
mkimage introduced a validation step to ensure that the 'default'
property under the /configurations node in a FIT image refers to a
valid subnode. This exposed an issue in the

Setting GPIO by reading the value of the GPRT register, toggling the
correct bit and then writing it causes input values to transfer to the
output. Here's how (example):
1) set gpio 17 and 18 as input.
2) set gpio 17 output value to 0 (read gprt, change 17 to 0, write).
3) set gpio 18 output value to 0 (read gprt, change 18 to 0, write).
The problem here is that because we set 17 as input, and it's a pull-up,
when we read gprt in step 3, the bit 17 will be 1 and not 0.
Instead of doing read/write/modify, the solution is to keep track
internally of the user set GPIOs, and replace the read step with this
static variable.
