Yes they are ... but see next lines ...

The PXA processor is an ARMv5TE. The cache-armv5.S in barebox is acutally
matched to be used with ARMv5TEJ and doesn't get along with a v5TE. Hence we
switch the core depenendy to v4t since the callbacks are fully compatible.

That's what in the historical commits of pxa's barebox support.

Cheers.
