Patch set updated for coreboot: PCIEXP_PLUGIN_SUPPORT: Change dependency on PCI access

Kyösti Mälkki (kyosti.malkki(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/17546 -gerrit commit 9cd42ab7744a3541a1ee44026e9d7693a9467c9d Author: Kyösti Mälkki <kyosti.malkki(a)gmail.com> Date: Sun Nov 20 20:39:56 2016 +0200 PCIEXP_PLUGIN_SUPPORT: Change dependency on PCI access Some PCI-e capability registers are located starting from 0x100, these are not accessible using the conventional PCI IO config operations at 0xcf8/0xcfc, unless PCI_CFG_EXT_IO was selected. Thus any feature that calls pcie_ext_find_capability() depends on either MMCONF_SUPPORT_DEFAULT or PCI_CFG_EXT_IO being enabled on the platform. In theory there can be system without MMCONF_SUPPORT, but with complete PCI Express configuration space available using PCI_CFG_EXT_IO. Do not use explicit PCI MMCONF operations here, but rely on the default PCI access method to be able to access all of the configuration space. While at it, convert to IS_ENABLED() everywhere in the source and organize Kconfig file better. With this change, AGESA and binaryPI platforms change to PCI_CFG_EXT_IO method here until MMCONF_SUPPORT_DEFAULT is activated for them.

Kyösti Mälkki (kyosti.malkki(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/17533 -gerrit commit ac44fc860cc3cba9f2ae04fa6a0351765272ace6 Author: Kyösti Mälkki <kyosti.malkki(a)gmail.com> Date: Sun Nov 20 11:03:13 2016 +0200 AGESA: Switch to MMCONF_SUPPORT_DEFAULT Vendorcode always does PCI MMCONF access once it is enabled via MSR. In coreboot proper, we don't give opportunity to make pci_read/write calls before PCI MMCONF is enabled via MSR. This happens early in romstage amd_initmmio() for all cores.
