40 # Compilation configuration for building little-endian XScale/arm-elf.
42 # NB: built with AH_REGOPS_FUNC to so that register accesses
43 # can be done using the Linux readl/writel functions on
44 # systems that need it.
46 # Reported to work on:
47 # Compulab's ARMBASE using ARMCORE GX
48 # (http://www.compulab.co.il/armbase.htm)
