[POWERPC] Fix Pegasos keyboard detection

2007-07-26T06:17:45+00:00

As of 2.6.22 the kernel doesn't recognize the i8042 keyboard/mouse
controller on the PegasosPPC.  This is because of a feature/bug in the
OF device tree: the "device_type" attribute is an empty string instead
of "8042" as the kernel expects.  This adds a secondary detection
which looks for a device whose *name* is "8042" if there is no device
whose *type* is "8042".

[POWERPC] Make the debugfs "powerpc" dir globally accessible

2007-07-10T11:53:50+00:00

The prom.c debugging code creates a "powerpc" directory in debugfs,
which is nice, but doesn't allow any other debugging code to stick things
under "powerpc" in debugfs. So make it global.

While we're there we should make the prom.c debugging code depend on
CONFIG_DEBUG_FS, because it doesn't work otherwise.

[POWERPC] Add a check for keyboard/mouse device nodes in check_legacy_ioport()

2007-07-10T11:53:49+00:00

The device tree for the MPC8641 HPCN does not implement the device type
property for I8042 nodes.

In addition to checking the I8042 node's device type, also match the
keyboard and/or mouse nodes' compatible property.

[POWERPC] Check cache coherency of kernel vs firmware

2007-05-12T01:32:50+00:00

check_cache_coherency() verifies that the cache coherency setting of
the kernel (CONFIG_NOT_COHERENT_CACHE) matches that left by the firmware,
as indicated by coherency-off device tree property.

[POWERPC] Generic check_legacy_ioport

2007-04-27T11:14:30+00:00

check_legacy_ioport makes only sense on PREP, CHRP and pSeries.
They may have an isa node with PS/2, parport, floppy and serial ports.

Remove the check_legacy_ioport call from ppc_md, it's not needed
anymore.  Hardware capabilities come from the device-tree.

[POWERPC] Remove unused inclusion of linux/ide.h

2007-04-12T17:55:14+00:00

Remove unneeded inclusion of linux/ide.h
It does not compile with CONFIG_BLOCK=n.

Remove asm/ide.h from ksyms file, it gets included earlier via
linux/ide.h.

Compile tested with all defconfig files.

[POWERPC] Automatically lmb_reserve() initrd

2007-03-08T04:43:35+00:00

At present, when an initrd is passed to the kernel used flat device
tree properties, the memory the initrd occupies must also be reserved
in the flat tree's reserve map, or the kernel may overwrite it.  That
makes life more complicated than it could be for the bootwrapper.

This patch makes the kernel automatically reserve the initrd's space.
That in turn requires parsing the initrd parameters earlier than they
are currently, in early_init_dt_scan_chosen() instead of
check_for_initrd().
