* - rename all the register related variables consistently
* - move all the interrupt twiddling code from the speedproc handlers into
* init_hwif_hpt366(), also grouping all the DMA related code together there
- * - merge two HPT37x speedproc handlers, fix the PIO timing register mask and
+ * - merge HPT36x/HPT37x speedproc handlers, fix PIO timing register mask and
* separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
* when setting an UltraDMA mode
* - fix hpt3xx_tune_drive() to set the PIO mode requested, not always select
