I've been testing the boostd for a few Marvell boards and seeing this error on the Thecus N2350 (Marvell Armada 385, dual-core CPU). The "bootflow scan scsi" command triggered the "CACHE: Misaligned operation at range" error. However, this error did not affect the result of the scan, i.e. the bootflow for scsi partition was created correctly, and u-boot is running normally.
Enabling CONFIG_SYS_DCACHE_OFF got rid of the errors altogether. Perhaps this is a case where the DCACHE is not required and should be turned off?
Please see the log after the break below.
Can you please try -next ? There's at least one SCSI related cache alignment fix there that's not in master, thanks.
Unfortunately I got the same errors. This time the ranges are different, of course.
master:

Can you debug to where these calls are so we can align these buffers? See 02660defdc8a ("scsi: Cache align temporary buffer") for an example.
