[U-Boot] armv5 and OMAP3 Question

The readme file for OMAP indicates that we compile using armv5 to "to allow more compilers to work"

We have our arch/arm/mach-omap2/omap3/lowlevel_init.S file also noting some special assembly insturctions becuse we use armv5. The barriers defined also indicate we're using CP15 instead of the separate barrier instructions for armv7 because we're using armv5 instead.

I just wonder in this day and age when we're noting a GCC version and generating warnings based on the GCC warning, do we still need to compile as armv5 any more? It seems like "to allow more compilers to work" would not really apply any more we're trying to push newer versions of GCC.

(please don't flame me, I am honestly curious).
