[PATCH] I2O: new sysfs attributes and Adaptec specific block device access and 64-bit DMA support
Changes:
- Added Bus-OSM which could be used by user space programs to reset a
channel on the controller
- Make ioctl's in Config-OSM obsolete in prefer for sysfs attributes and
move those to its own file
- Added sysfs attribute for firmware read and write access for I2O
controllers
- Added special handling of firmware read and write access for Adaptec
controllers
- Added vendor id and product id as sysfs-attribute to Executive classes
- Added automatic notification of LCT change handling to Exec-OSM
- Added flushing function to Block-OSM for later barrier implementation
- Use PRIVATE messages for Block access on Adaptec controllers, which are
faster then BLOCK class access
- Cleaned up support for Promise controller
- New messages are now detected using the IRQ status register as
suggested by the I2O spec
- Added i2o_dma_high() and i2o_dma_low() functions
- Added facility for SG tablesize calculation when using 32-bit and
64-bit DMA addresses
- Added i2o_dma_map_single() and i2o_dma_map_sg() which could build the
SG list for 32-bit as well as 64-bit DMA addresses
