I'm really sorry to have started this, but for completeness here is the rest of the story. The hypothetical scenario is a developer that maintains u-boot for multiple platforms. Using a codesourcery or eldk (from denx.de) toolchain one can use the appropriate -march= to get the right code from th

I believe that the libgcc.a in our toolchain contains Thumb-2 code. I verified this by doing objdump on libgcc.a and I see combinations of 16 and 32 bit instructions. So does that mean that the toolchain is only usable for ARM versions that support Thumb-2? Thanks, John

While trying out the u-boot-next branch I found a problem. First some explanation. On most platforms, u-boot is linked to the address it will first start running. For example when using NOR flash U-Boot will be linked to an address in flash. Very early in the boot process, U-Boot copies itself
