    [PATCH] crc32 speedup/use anywhere · 0c0c1d48
    Brian Murphy authored
    This patch combines my patch which statically initialises the crc32
    tables so they can be used at any time (during initialisation) and
    Joakim Tjernlund's patch to speed up the crc calculations by doing word
    operations instead of exclusively byte.
    
    The crc routines are used extensively in jffs2 where speed is very
    important.
    
    I need the crc32 routines to calculate a checksum on values read from an
    eeprom which contain cpu speed and memory size information - so they are
    needed very much earlier in the initialisation process than they are
    currently available.
