    mtd: bcm47xxsflash: use ioremap_cache() instead of KSEG0ADDR() · 5651d6aa
    Brian Norris authored
    Using KSEG0ADDR makes code highly MIPS dependent and not portable.
    Thanks to the fix a68f3768 ("MIPS: io.h: Define `ioremap_cache'") we can
    use ioremap_cache which is generic and supported on MIPS as well now.
    
    KSEG0ADDR was translating 0x1c000000 into 0x9c000000. With ioremap_cache
    we use MIPS's __ioremap (and then remap_area_pages). This results in
    different address (e.g. 0xc0080000) but it still should be cached as
    expected and it was successfully tested with BCM47186B0.
    
    Other than that drivers/bcma/driver_chipcommon_sflash.c nicely setups a
    struct resource for access window, but we wren't using it. Use it now
    and drop duplicated info.
