I replaced the .dts* files with the ones provided by the new board BSP. Actually, they differ quite a lot from the Altera SoC FPGA .dts* files in the Linux tree. Then, I compiled and flashed the SD card. I enabled CONFIG_DEBUG_LL with no change. CONFIG_DEBUG_PBL doesn't exist in my case. For some reason, the defconfig I built upon, uses Barebox v2021.07.0, which is probably outdated...
