I tested u-boot on my Dreamplug and found it was not working correctly. I raised a bug for Debian[1] but I have also tested with the mainline version of u-boot and found the same issues. This is the second issue that I found, and it causes u-boot to not detect the SPI flash on the system. I bisected the issue to the following commit: commit 6aaf76beb131c2ff2b7184c2d63c2c63e5ab339c Author: Chris Packham Date: Wed Nov 21 22:22:23 2018 +1300 arm: kirkwood: configs: dreamplug: Convert to DM_SPI Enable CONFIG_DM_SPI=y and CONFIG_DM_SPI_FLASH=y in the defconfig.
