sparc32: drop tadpole specific code

2014-05-19T02:01:29+00:00

tadpole.c assigned cpu_pwr_save based on the current configuration.
The rest of the tadpole.c file was only used if cpu_pwr_save was
dereferenced.
But this variable was never dereferenced - and I went back to a 2.6.12
kernel to check (from June 2005) - and not even then was it used.

Drop this code as it has not been in use for ~10 years.

sparc: fix MSI build failure on Sparc32

2013-10-03T00:02:35+00:00

Commit ebd97be635 ('PCI: remove ARCH_SUPPORTS_MSI kconfig option')
removes the ARCH_SUPPORTS_MSI Kconfig option that allowed
architectures to indicate whether they support PCI MSI or not. Now,
PCI MSI support can be compiled in on any architecture thanks to the
use of weak functions thanks to 4287d824f265 ('PCI: use weak functions
for MSI arch-specific functions').

So, architecture specific code is now responsible to ensure that its
PCI MSI code builds in all cases, or be appropriately conditionally
compiled.

On Sparc, the MSI support is only provided for Sparc64, so the
ARCH_SUPPORTS_MSI kconfig option was only selected for SPARC64, and
not for the Sparc architecture as a whole. Therefore, removing
ARCH_SUPPORTS_MSI broke Sparc32 configurations with CONFIG_PCI_MSI=y,
because the Sparc-specific MSI code is not designed to be built on
Sparc32.

To solve this, this commit ensures that the Sparc MSI code is only
built on Sparc64. This is done thanks to a new Kconfig Makefile helper
option SPARC64_PCI_MSI, modeled after the existing SPARC64_PCI. The
SPARC64_PCI_MSI option is an hidden option that is true when both
Sparc64 PCI support is enabled and MSI is enabled. The
arch/sparc/kernel/pci_msi.c file is now only built when
SPARC64_PCI_MSI is true.

sparc,leon: support for GRPCI1 PCI host bridge controller

2013-03-20T18:06:54+00:00

Some of the GRPCI1 cores does not support detection of all PCI
errors, the default is therefore limited PCI error handling.
The property all_pci_errors my be set by the boot loader to
enable interrupt on all PCI errors.
