This series aims to upstream fixes that have been in the Calxeda firmware version of U-Boot for ages. The first two patches fix reset, both for Highbank and Midway. Patches 3-5 add support for larger hard disks, so U-Boot can now access sectors from beyond 2 TB on larger disks. Patch 6 and 7 teach U-Boot not to touch the FDT memory node. The primary Calxeda firmware detects the amount of memory (it has a DIMM socket!) at boot time and populates the memory node accordingly. U-Boot would overwrite the node with a fixed value, most commonly getting lost of any memory beyond 4 GB on Midway systems. I have been told that this fix has been disliked before, so I am open to a discussion on how to address this problem. The final patch fixes Highbank's SATA setup, which requires some special care (cf. the sata_highbank.c driver in Linux).
There are actually more patches [1] in the last official firmware, but most of the others only make sense with some special management firmware versions that never made it to the light. I extracted the most useful and important patches from there and rebased them on top of the current master. With them I can happily use upstream U-Boot on a Midway system - I haven't had time to test it on Highbank, though. Please review, comment and hopefully apply them! Cheers, Andre.
