It used to set the fixed physical address at which ubldr[.bin] was linked to run, but now ubldr is self-relocating and can be loaded at any 2mb boundary (really 1mb boundary on most arm systems). It should be noted that ubldr is obsolete as well; only ubldr.bin is needed. The older version with the elf headers intact was supposed to be kept around "for a few weeks, until crochet can be adjusted to not refer to it". That was like 3 years ago, but it never got removed. Hmmm, actually, since UBLDR_LOADADDR does end up stored in the elf headers, I guess if you're using the obsolete ubldr with headers intact, maybe it is influencing uboot's behavior and causing failures. -- Ian
