commit 2464d14624b67701b90c874bd5479900bc1765df Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Sat Jan 17 18:08:40 2015 +0200
pcengines/apu1: Fix and cleanup devicetree
Change gpp_configuration to GPP_CFGMODE_X1111 (was X4000), this is done to only advertise x1 lanes for PCIe link 0:15.0.
Remove functions 0:12.1 and 0:13.1 that do not exist in the hardware.
Disable 0:14.1 IDE controller, as it would only be used with SATA ports 4 and 5 that are not populated with connectors in the hardware.
Disable 0:14.2 HD audio, as it is not implemented in the hardware
Disable 0:14.4 PCI-to-PCI bridge, as no PCI slots are implemented and some pins are used for GPIO in the hardware. Remove related IRQ entries for the bus that does not exist from MP tables.
Disable 0:14.5 OHCI controller, as ports behind this USB1.1 -only controller are not populated in the hardware.
Fix some alignment and whitespace.
To my knowledge these changes are not included with SAGE release pcengines.apu_139_osp.tar.gz, but that tarball does not contain either devicetree.cb or a pre-compiled static.c file so I cannot tell for sure.
