If the PXA is broken, then it should be fixed, but NOT by  making  it
like  the  other  ARM boards which are (IMHO) broken by design. [It's
just that we didn't have enough free resources (or volunteers???)  to
fix the ARM memory layout.]

ARM still suffers from the many things ARMBoot did differently.
