[U-Boot] Compilation error - MPC8536DS

[U-Boot] Compilation error - MPC8536DS

[Felix Radensky]

Hi,

I'm hitting the error  below when compiling the latest git u-boot for 
MPC8536DS target.
I'm using toolchain from Freescale BSP for this board. ld version is 
2.18.50.20080215,
gcc version is 4.3.2. Any ideas how to fix this ?

Seems recent versions of GCC have changed their behaviour (once
again) when (not) using load/store multiple instructions, which
causes them to generate bigger (but allegedly more correct) code.

The code builds fine with gcc-4.2.2.

Best regards,

Thanks, I'll switch to ELDK 4.2 then.
