  • 6d2170be4   powerpc/4xx: Extended DCR support v2 ... Browse Code »

    This adds supports to the "extended" DCR addressing via the indirect
    mfdcrx/mtdcrx instructions supported by some 4xx cores (440H6 and
    later).

    I enabled the feature for now only on AMCC 460 chips.

  • 4c75a6f44   [POWERPC] Generic DCR infrastructure ... Browse Code »

    This patch adds new dcr_map/dcr_read/dcr_write accessors for DCRs that
    can be used by drivers to transparently address either native DCRs or
    memory mapped DCRs. The implementation for memory mapped DCRs is done
    after the binding being currently worked on for SLOF and the Axon
    chipset. This patch enables it for the cell native platform
