powerpc: Remove superfluous bootmem includes

2014-11-09T22:59:26+00:00

Lots of places included bootmem.h even when not using bootmem.

powerpc: Added PCI MSI support using the HSTA module

2014-04-30T22:26:30+00:00

The PPC476GTR SoC supports message signalled interrupts (MSI) by writing
to special addresses within the High Speed Transfer Assist (HSTA) module.

This patch adds support for PCI MSI with a new system device. The DMA
window is also updated to allow access to the entire 42-bit address range
to allow PCI devices write access to the HSTA module.

powerpc/4xx: Fix section mismatch in ppc4xx_pci.c

2014-04-28T06:32:53+00:00

This patch fixes this section mismatch:

WARNING: vmlinux.o(.text+0x1efc4): Section mismatch in reference from
the function apm821xx_pciex_init_port_hw() to the function
.init.text:ppc4xx_pciex_wait_on_sdr.isra.9()

The function apm821xx_pciex_init_port_hw() references the function
__init ppc4xx_pciex_wait_on_sdr.isra.9().  This is often because
apm821xx_pciex_init_port_hw lacks a __init annotation or the
annotation of ppc4xx_pciex_wait_on_sdr.isra.9 is wrong.

apm821xx_pciex_init_port_hw is only referenced by a struct in
__initdata, so it should be safe to add __init to
apm821xx_pciex_init_port_hw.

powerpc/pci: Support per-aperture memory offset

2013-05-06T03:40:40+00:00

The PCI core supports an offset per aperture nowadays but our arch
code still has a single offset per host bridge representing the
difference betwen CPU memory addresses and PCI MMIO addresses.

This is a problem as new machines and hypervisor versions are
coming out where the 64-bit windows will have a different offset
(basically mapped 1:1) from the 32-bit windows.

This fixes it by using separate offsets. In the long run, we probably
want to get rid of that intermediary struct pci_controller and have
those directly stored into the pci_host_bridge as they are parsed
but this will be a more invasive change.

powerpc/44x: pci: Add a want_sdr flag into ppc4xx_pciex_hwops

2011-12-09T12:47:48+00:00

Currituck doesn't need nor use SDR so aborting the pci setup if there is
no sdr-base would be bad.

Add a flag to ppc4xx_pciex_hwops for the backends to state if they need
SDR and then only complain and abort if they do and it's not found in
the device tree.
