2009-09-15T19:02:15+00:00

next-20090813 randconfig build breaks Discretix SEP driver when
configured with CONFIG_PCI=n.

Staging: sep: use ioremap helpers

2009-09-15T19:02:15+00:00

Whee lots of code vanishes. While we are it note various existing stuff
that couldn't work but was ifdeffed in this area.

Staging: sep: untangle the register_fs code

2009-09-15T19:02:15+00:00

While goto can be useful for cleaner cleaning up in C (as Linux sometimes
does and I think Linus borrowed stylistically from Amiga) you can overdo it.
Here is a fine fine example of when it's overkill

The SEP time setting stuff can now get a hoover

Staging: sep: clean up command sending

2009-09-15T19:02:15+00:00

Split out the debug dumping functionality. Clean up the rest. For the moment
leave the hideous cache flush in there as the code needs fixing to use
the dma_map_sg interfaces not its own crazed table functions

Staging: sep: flow ioctl cleanup

2009-09-15T19:02:15+00:00

Simple ioctl taking a single numeric argument so ditch the structs and
weirdness. While we are it lock it properly and fix the error returns.

Staging: sep: kick out various fields we can prove are not needed

2009-09-15T19:02:15+00:00

#1: sep->cache_addr is assigned to sep->rar_addr and never changed
    sep->rar_addr is never assigned after this point

#2: sep->cache_bus ditto for sep->rar_bus

#3  sep->rar_region_addr is assigned but necer used

#4  sep->io_addr is in fact private to the probe function and
    the same as the reg_addr

#5  The remainig sep->io fields are in fact function locals

#6  sep->message_shared_area is assigned once from sep->shared_area
    sep->shared_area does not then change

#7  sep->shared_addr and sep->shared_area_addr are the same thing, ditto
    for the bus addresses.

Staging: sep: Implement some proper open/close methods

2009-09-15T19:02:15+00:00

Use the mutex as a protection for open close rather than leaving it hanging
invalidly across userspace.

Staging: sep: tidy firmware load

2009-09-15T19:02:15+00:00

Start by removing unused fields and then work this back to eliminate unused
chunks of the firmware loading ioctl (ie almost all of it)

Also fix the wrong handling of shared allocations and allocate the rar
region properly with dma_alloc_coherent not kmalloc, as it is device shared.
