PCI: Assign resources before drivers claim devices (pci_scan_bus())

2015-03-12T20:04:01+00:00

Previously, pci_scan_bus() created a root PCI bus, enumerated the devices
on it, and called pci_bus_add_devices(), which made the devices available
for drivers to claim them.

Most callers assigned resources to devices after pci_scan_bus() returns,
which may be after drivers have claimed the devices.  This is incorrect;
the PCI core should not change device resources while a driver is managing
the device.

Remove pci_bus_add_devices() from pci_scan_bus() and do it after any
resource assignment in the callers.

sparc32: fix sparse warnings in pcic.c

2014-05-19T02:01:27+00:00

Fix following warnings:
pcic.c:164:14: warning: symbol 'pcic_regs' was not declared. Should it be static?
pcic.c:165:14: warning: symbol 'pcic_speculative' was not declared. Should it be static?
pcic.c:166:14: warning: symbol 'pcic_trapped' was not declared. Should it be static?
pcic.c:332:66: warning: Using plain integer as NULL pointer
pcic.c:344:66: warning: Using plain integer as NULL pointer
pcic.c:539:38: warning: Using plain integer as NULL pointer
pcic.c:677:1: warning: symbol 'pcic_pin_to_irq' was not declared. Should it be static?
pcic.c:783:6: warning: symbol 'pcic_nmi' was not declared. Should it be static?

Add extern for pcic_regs.
Define a few variables static.
Replace 0 with NULL.
Delete unused funtion pcic_pin_to_irq().
Include kernel.h so we could drop declaration of
t_nmi and add prototype for pcic_nmi.

sparc32: introduce asm-generic/io.h

2014-05-02T05:30:21+00:00

Use asm-generic/io.h definitions where applicable.
The inxx() and outxx() methods whcih was duplicated in pcic.c +
leon_pci.c are replaced by a set of static inlins from asm-generic/io.h

iomap.c is replaced by the generic versions, but are still
present to support sparc64.

sparc32: replace flip_dword() with swab32()

2014-05-02T05:30:21+00:00

The latter is a generic implmentation.
flip_{,d}word() is sparc32 specific and will be dropped.

SPARC: drivers: remove __dev* attributes.

2013-01-03T23:57:04+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The PCI core provides a generic pcibios_setup() routine.  Drop this
architecture-specific version in favor of that.
