Looking at the XScale manual we could actually implement
ARM_FEATURE_XSCALE as (cpu->midr & 0xffff0000 == 0x69050000)
[Vendor=intel, arch=ARMv5TE], and ARM_FEATURE_IWMMXT as
(cpu->midr & 0xffffe000 == 0x69054000) [Vendor=intel,
arch=ARMv5TE, Core Generation=2]... Doesn't really gain
us much, of course :-)
thanks
