++ * olpcpci.c - Low-level PCI config space access for OLPC systems
++ * without the VSA PCI virtualization software.
++ *
++ * The AMD Geode chipset (GX2 processor, cs5536 I/O companion device)
++ * has some I/O functions (display, southbridge, sound, USB HCIs, etc)
++ * that more or less behave like PCI devices, but the hardware doesn't
++ * directly implement the PCI configuration space headers.  AMD provides
++ * "VSA" (Virtual System Architecture) software that emulates PCI config
++ * space for these devices, by trapping I/O accesses to PCI config register
++ * (CF8/CFC) and running some code in System Management Mode interrupt state.
++ * On the OLPC platform, we don't want to use that VSA code because
++ * (a) it slows down suspend/resume, and (b) recompiling it requires special
++ * compilers that are hard to get.  So instead of letting the complex VSA
++ * code simulate the PCI config registers for the on-chip devices, we
++ * just simulate them the easy way, by inserting the code into the
++ * pci_write_config and pci_read_config path.  Most of the config registers
++ * are read-only anyway, so the bulk of the simulation is just table lookup.
