Log:
Fix support for machines with default MP Table configurations:
- Fix the MP Table pci bridge drivers to not probe the configuration table
unless we actually have one. Machines using a default configuration do
not have such a table.
- Only allow default configuration types of 5 (ISA + PCI) and 6 (EISA +
PCI) as the others are not likely to work. Types 1 through 4 use an
external APIC (probably with 80486 processors) which we certainly do not
support, and type 7 uses an MCA bus which has not been tested with the
new MP Table code.
- Correct the fact that the single I/O APIC in a default configuration has
an ID of 2, not 0.
- Fix off by one errors in setting the bus types from the default_data[]
arrays for default configurations.
- Explicitly configure each of the 16 interrupt pins on the sole I/O APIC
when using a default configuration. This is especially helpful for type
6 (EISA + PCI) since the EISA interrupts need to have their polarity
programmed based on the values in the ELCR.
Much thanks to the submitter and tester who endured several rounds of
testing to get this fixed.
