u-boot O2 issue
Hi all,
I am working on TI's arm926ejs based processor 'DM350'.
I compiled my ported u-boot (1.1.4) and kernel (2.6.18) with open source gcc 4.1.1 tool-chain (downloaded from buildroot).
If I disable O2 flag while compiling the u-boot, I am able to boot the kernel properly.
If I enable O2 flag at the time of u-boot compilation, my kernel hangs after giving message "uncompressing the kernel........".
I suspect some issue with kernel command line passed from u-boot to kernel.
Let me know if anyone of you have come accross this kinf of issue.
Thanks.

I rather suspect a toolchain bug here, because I've seen other problems with the toolchain of buildroot.
