[POWERPC] QE: fix Kconfig 'select' warning with UCC_FAST

2007-05-23T12:23:55+00:00

The UCC_GETH Kconfig option in drivers/net/Kconfig had a line to select the
UCC_FAST option is arch/powerpc/sysdev/qe_lib/Kconfig, which is only used
on PowerPC builds.  On other architectures, this would generated a warning.
The fix is to have UCC_FAST depend on UCC_GETH.

[POWERPC] Remove warning in mpic.c

[POWERPC] Add Marvell mv64x60 PCI bridge support

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

This patch adds PCI bridge support for the Marvell mv64x60 chip.
We also provide the ability to read/write the mv64x60 hotswap
register via sysfs if the hs_reg_valid property is set in the
device tree.

[POWERPC] Create Marvell mv64x60 I2C platform_data

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

This patch creates platform_device entries for the Marvell mv64x60
I2C ports, based on information contained in device tree.

This driver (like the other mv64x60 drivers) are unusual in that it
works on both the MIPS and PowerPC architectures.  Because of that,
the drivers do not support the normal PowerPC of_platform_bus_type.
They support platform_bus_type instead.

[POWERPC] Create Marvell mv64x60 ethernet platform_data

ethernet controller ports, based on information contained in the

[POWERPC] Create Marvell mv64x60 MPSC (serial) platform_data

[POWERPC] Add interrupt support for Marvell mv64x60 chips

2007-05-12T01:32:49+00:00

There are 3 interrupt groups each with its own status/mask registers.
We use a separate struct irq_chip for each interrupt group and handle
interrupts in two stages or levels: level 1 selects the appropriate
struct irq_chip, and level 2 selects individual interrupts within
that irq_chip.

[POWERPC] Change rheap functions to use ulongs instead of pointers

2007-05-10T04:01:43+00:00

The rheap allocation functions return a pointer, but the actual value is based
on how the heap was initialized, and so it can be anything, e.g. an offset
into a buffer.  A ulong is a better representation of the value returned by
the allocation functions.

This patch changes all of the relevant rheap functions to use a unsigned long
integers instead of a pointer.  In case of an error, the value returned is
a negative error code that has been cast to an unsigned long.  The caller can
use the IS_ERR_VALUE() macro to check for this.

All code which calls the rheap functions is updated accordingly.  Macros
IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().

Also added error checking to rh_attach_region().

of_get_mac_address() returns a const pointer, so the result
should be stored in a const pointer.

[POWERPC] Abolish powerpc_flash_init()

2007-05-08T05:09:26+00:00

powerpc_flash_init() implements a broken way of probing for flash
devices supported by the physmap_of driver.  It finds all nodes in the
device tree with device_type=="rom" and instantiates of_platform
devices for them.  This is fundamentally incompatible with the normal
and correct way of probing for of_platform_bus_probe().  Platforms
which relied on powerpc_flash_init()s behaviour (none are in-tree)
will have to update their platform probing code to correctly probe
busses containing flash devices.
