 a utility designed to make updating the QSPI flash memory
 easier.

+Additionally, it is possible to use u-boot for updating the
+QSPI with new boot.bin and u-boot.itb images with the u-boot
+commands below:
+
+Flashing u-boot.itb:

+    $ sf erase 0x200000 +$filesize

+
 It is possible to boot the Buildroot generated SD card image without
 updating the QSPI boot.bin image, so this is an optional step.

I know little about the technical details of Kria, but the set looks
formally well written and understandable, so:

The "the" IMHO sounds odd, so I dropped it.
