Author: mcayland Date: Mon Aug 19 09:40:12 2013 New Revision: 1209 URL: http://tracker.coreboot.org/trac/openbios/changeset/1209 Log: SPARC32: fix romvec stdin/stdout field initialisation Previously the romvec stdin/stdout ihandles were configured so that they were set to the current stdin and stdout paths at initialisation time. Unfortunately as stdin/stdout can be changed with the input and output words, they can end up pointing to invalid ihandles causing a crash when trying to output to the console. Fix this by pointing the romvec structure to the address of the stdin/stdout variables so that they are always in sync. Similarly we also resolve the text path stdin/stdout variables at boot time to ensure that they will never be stale.

[PATCH 1/2] PPC: Fix PCI configuration space address access

by Mark Cave-Ayland

This patch corrects two long-standing bugs with PPC PCI configuration space access. Firstly fix the calculation of PCI configuration space addresses by the PCI_ADDR macro; this was incorrectly using arch->cfg_base which is the mapped address and has nothing to do with the PCI configuration space address. Instead just set bit 31 to initiate a configuration cycle as per the PCI specification. Secondly, fix pci_config_read32() and pci_config_write16() which were incorrectly adding the register offset to the PCI IO dataport address causing them to write into unknown address space for registers > 0. It appears that this only worked purely by coincidence with QEMU due to the way in which the configuration address was calculated for an oversized PCI configuration IO dataport MemoryRegion.

Author: mcayland Date: Mon Sep 2 15:46:01 2013 New Revision: 1226 URL: http://tracker.coreboot.org/trac/openbios/changeset/1226 Log: PCI: switch calculation of host PCI memory base to use an offset Instead of using two different variables to track the absolute values of the PCI memory base and the host memory base, change the host memory base to be an offset which is added to the PCI memory base during conversion. As a consequence of this, the code in pci_bus_addr_to_host_addr() can be unified to be consistent across all architectures. Note that this commit also renames arch->host_mem_base to arch->host_pci_base in order to better describe its function.
