Re: Further OCP cleanups

David Gibson wrote:

The patch below follows up on paulus' cleanups of the OCP EMAC driver
with further cleanups in the OCP layer and its drivers.  It does
several things:
	- Renames the ocpdev field of struct ocp_driver to private,
which is more descriptive of its actual function.
	- removes a redundant INIT_LIST_HEAD from ocp_register
	- moves the registration of the miscdev for the GPIO driver
into the driver itself, from ocp.c
	- removes the irq_resource field of the ocp_enet_private
structure, since it was essentially unused.
	- with the help of those last two remove the ugly switch
statements from ocp_register() and ocp_unregister()
	- removed the procdir field from ocp_driver structure, since
it always had the same value
	- remove the fops field from the ocp_driver structure, since
it was only used by the GPIO driver and then always held the same
value
	- cleanup of the MAL DCR handling code.  No more mal.sh,
autogenerated ibm_ocp_mal.c or MBASE[].  Instead we use a magic macro
to generate a switch across the MAL base address.  More to come which
will cause this to be completely optimised away on machines with only
one MAL (the majority)
	- Move the IIC_DEV macro into the .c files which use it, since
it clearly belongs to the I2C code itself, rather than to the OCP
layer.  More to come which will eliminate this macro entirely, as
EMAC_DEV was removed by paulus' patch
	- Update ibm_ocp_debug.c to work with paulus' changes, also
cleanup some ugliness
	- Remove the 'priv_index', 'devfs_handle' and 'active' fields
from struct ocp_driver, since they appear to be unused.

If you have no objections I will commit this to linuxppc_2_4_devel.

David,

  The IIC_DEV change is ok and the _debug.c changes are fine but  I
would like to hold off on the rest.  I am not satisfied with the tx/rx
channel mal case/switch stuff in the *_enet.c and the ibmnp405h.c was
missed
