* ssb: fix init regression with SoCsHauke Mehrtens2012-01-061-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 329456d1ffb416c220813725b7363cda9975c9aa upstream. This fixes a Data bus error on some SoCs. The first fix for this problem did not solve it on all devices. commit 6ae8ec27868bfdbb815287bee8146acbefaee867 Author: Rafał Miłecki <zajec5@gmail.com> Date: Tue Jul 5 17:25:32 2011 +0200 ssb: fix init regression of hostmode PCI core In ssb_pcicore_fix_sprom_core_index() the sprom on the PCI core is accessed, but the sprom only exists when the ssb bus is connected over a PCI bus to the rest of the system and not when the SSB Bus is the main system bus. SoCs sometimes have a PCI host controller and there this code will not be executed, but there are some old SoCs with an PCI controller in client mode around and ssb_pcicore_fix_sprom_core_index() should not be called on these devices too. The PCI controller on these devices are unused, but without this fix it results in an Data bus error when it gets initialized.

* MIPS: Fix SSB PCIcore IO resource managementAndreas Ferber2010-04-121-29/+0
| | | | | | | | | | | | | | | | | | | | | | | The SSB PCIcore code reused the IO resource fixup code from the original 2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack for doing PCI IO resource configuration back then (the boot loader doesn't configure PCI devices on this platform). However, this code is no longer necessary since the kernel now can do PCI resource management fine all by itself, so remove the old code. When removing the code, it becomes obvious that the mem_offset setting in the PCIcore driver was wrong, however this was masked by the fixup code before, except in a few cases involving yenta_socket. For BCM47xx, the correct offset is 0, and since this is the only device using PCIcore in host mode, the offset can simply be removed unconditionally.

* [SSB]: add Sonics Silicon Backplane bus supportMichael Buesch2007-10-101-0/+576
SSB is an SoC bus used in a number of embedded devices. The most well-known of these devices is probably the Linksys WRT54G, but there are others as well. The bus is also used internally on the BCM43xx and BCM44xx devices from Broadcom. This patch also includes support for SSB ID tables in modules, so that SSB drivers can be loaded automatically.
