Greetings,
The size in the ldscripts is controlled by ROM_IMAGE_SIZE in the mainboard config file. With care, it should be changable, but there is a good bit of magic in there (I'm trying to get rid of some of that in the boards I have, but it is slow going and some of it is hard to get rid of).
Of course, if the selected size is too small, bad things happen (I don't know if it will build a broken image, or just fail to build).
The thing is, a build where ionly the actual size needed gets used presents some real problems for getting target addresses right.
G'day, sjames

The .rom starts at 0xffff4000, which gives you a 49152-byte section.
I think the .ldscript is giving a fixed-size linuxbios without regard to how big it actually is, which means tuning via things like max log message etc. is no longer a real option. It also means my etherboot, which is 17K, no longer fits together with linuxbios into 64K.
OK, back to the drawing board :-)
