    [PATCH] ARM: 2753/1: move ixdp* cpld mappings · 91f6a589

    All ixdp platforms currently have a cpld mapped in at 0xfafff000.
    Since this address is not 1M-aligned, a regular page mapping will be
    used instead of a section mapping, which opens up the possibility of
    triggering ixp2400 erratum #66 as we only do the XCB=101 workaround
    thing for section mappings.
    There is still a lot of space higher up in the virtual memory map
    for 1M mappings, so move the cpld mapping to 0xfe000000 and make it
    1M big so that a section mapping will be used for it.
