Somebody in the thread at some point said:

| According to the available datasheet[1] the core of the s3c6410 is a
| ARM1176JZF-S which is armv6 [2].

Mmm Graeme already noted it.

| If using the newer instructions brings even the slightest acceleration
| it should be used imho.

If the packaging tools just can't deal with it, we probably forget the
benefit from "the slightest acceleration" quite quickly as our rootfs
melts down.  So it needs the packaging people to see a working way
forward as well I think.

| Also, the s3c6410 has an FPU (ARM VFP), so I don't think it makes any
| sense to use the softfloat-armv4-packages.

That's a good point.  Not having separate arch in packaging means
turning our back on the FPU, for some things that would be very painful.
