[POWERPC] Create common fsl pci/e files based on 86xx platforms

2007-07-23T15:27:07+00:00

Move
arch/powerpc/platforms/86xx/pci.c -> arch/powerpc/sysdev/fsl_pci.c
arch/powerpc/sysdev/fsl_pcie.h -> arch/powerpc/sysdev/fsl_pci.h
as the base to unify 83xx/85xx/86xx pci and pcie.

Add CONFIG_FSL_PCI to build fsl_pci.c for Freescale pci and pcie option.
The code still works for 86xx platforms.

[CELL] driver for DDR2 memory on AXON

2007-07-20T19:41:42+00:00

The Axon bridge chip used on new Cell/B.E. based blade servers
comes with a DDR2 memory controller that can be used to
attach cheap memory modules, as opposed to the high-speed
XDR memory that is used by the CPU itself.

Since the memory controller does not participate in the
cache coherency protocol, we can not use the memory direcly
for Linux applications, but by providing a block device
it can be used for swap space, temporary file storage and
through the use of the direct_access block device operation
for mapping into user addresses, when it is mounted with
an appropriate file system.

[POWERPC] Create add_rtc() function to enable the RTC CMOS driver

2007-07-11T03:24:40+00:00

In order to use the RTC CMOS driver, each architecture must register a
platform device for the RTC.

This creates a function to register the platform device based on the RTC
device node and verifies that the RTC port against the hard-coded value
in asm/mc146818rtc.h.

[POWERPC] Remove PCI-e errata for MPC8641 silicon ver 1.0

2007-06-29T06:58:17+00:00

Remove errata for PCI-e support of Rev 1.0 of MPC8641 since its considered
obselete and is not production level silicon from Freescale.

[POWERPC] Pass the pci_controller into pci_exclude_device

2007-06-29T06:57:22+00:00

There are times that we need to know which controller we are on to decide
how to exclude devices properly.  We now pass the pci_controller that we
are going to use down to the pci_exclude_device function. This will
greatly simplify being able to exclude the PHBs in multiple controller
setups.

[POWERPC] Don't link timer.o for powerpc systems using generic rtc

2007-06-25T06:58:07+00:00

With both generic rtc and powerpc timer suspend / resume code now in the
(powerpc.git) tree, powerpc platforms using the generic timer and enabling
power management will have timer.o linked in the kernel, which they don't
need. Moreover, it will likely WARN_ON(!ppc_md.get_rtc_time), save
zero-time and return no error on suspend...

As a possible solution we can choose not to build timer.o when RTC_CLASS
is enabled.  However, I can imagine systems with 2 rtc's, one served by the
ppc-rtc, another one generic built as a module, in which case using the
ppc-rtc for suspend / resume will be impossible.  Not to say, that such a
configuration would be ugly...

[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 MPSC (serial) platform_data

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

This patch creates platform_device entries for the Marvell mv64x60
MPSC (multi-protocol serial controller) ports, based on information
contained in the 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] 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] 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.
