The Calxeda Highbank and Midway systems have not been updated in a while, so were gathering more and more warning messages about not being DM compliant over time.
To avoid the support being removed, update the board to comply with modern U-Boot standards: - Enable OF_CONTROL, and use the DTB provided by previous firmware stages. - Convert the XGMAC network driver over to the driver model. - Read the actual DRAM size (as detect by the management processor) from the DTB and use that to populate the memory node, and U-Boot internal idea of DRAM.
Access to SATA drives broke with commit 66c54f1a3e46 ("scsi: Simplify scsi_read()/_write()") before the v2020.01 release, and remains non-functional with this series for now. Reverting that commit (and massaging it a bit) brought it back to life. I will send a proper patch once I wrapped my head around the SCSI/SATA/AHCI/DM-block connections.
To test this build, you can use chain-loading on an existing installation (firmware updates in flash on those boards are not trivial): $ mkimage -A arm -O u-boot -T standalone -C none -a 0x8000 -e 0x8000 \ -d u-boot.bin -n U-Boot /srv/tftp/u-boot-highbank.img => tftpboot 0x8000 u-boot-highbank.img => bootm 0x8000
Cheers, Andre
