When I got 1.1.4, I get the infamous message about how u-boot needs

software FP whereas my gcc is set up for hardware fp.
What I would LIKE to know is why 1.1.2 builds just fine but 1.1.4
does
not.
There have been so many changes between 1.1.2 and 1.1.4 that it's difficult to tell which specific change causes the problem, but if you check the "make" output you can clearly see where the problem is coming from - your compiler fails to provide the required softfloat routines. Which is kind of funny, since there are not so many ARM systems with FPU around.
My recommendation is to fix the toolchain.
It certainly does seem odd that it was built with the floating point hardware stuff compiled in, given that the unit has no floating point support. My hands are a bit tied in that I don't have control over the toolchain, but I will bring it up with them. If I have to, I suppose I'll just have to stick with the 1.1.2 build, and figure out how to make it work.
Best regards,

Maybe you can use the ELDK instead of your toolchain...
