    SubjectRe: [PATCH 1/2] Use common cpu_is_xxx() macros on AT91 and AVR32

    > Several drivers shared between AT91 and AVR32 chips use cpu_is_xxx()
    > to handle CPU-specific differences. Currently, such code needs to be
    > inside #ifdef CONFIG_ARCH_AT91 because the macros don't exist on AVR32.
    > By defining the same macros on both AT91 and AVR32, these #ifdefs can
    > be eliminated. Since the macros will evaluate to a constant value for
    > CPUs that aren't supported by the current architecture, any code that
    > is only needed on AT91 will be optimized away on AVR32 and vice versa.
