From: Philip Prindeville <philipp@xxxxxxxxxxxxxxxxxxxxx>
Many applications running embedded linux use Geode-based single-board
computers. There are many reasons for this, but the low cost bill-of-
materials and the maturity and multiple sourcing of the Geode processor
are amongst the most significant. This collection of patches supplements
the Geode platform support by adding 2 new platforms (Geos and Net5501),
and enhancing one (Alix2) with GPIO-based button support. It also adds
support for detecting Coreboot BIOS and parsing its tables.
Philip Prindeville (4):
Add support for finding the end-boundary of an E820 region given an
address falling in one such region. This is precursory
functionality for Coreboot loader support.
Add support for Coreboot BIOS detection. This in turn can be used by
platform drivers to verify they are running on the correct
hardware, as many of the low-volume SBC's (especially in the
Atom and Geode universe) don't always identify themselves via
DMI or PCI-ID.
Trivial platform driver for Traverse Technologies Geos and Geos2
single-board computers. Uses Coreboot BIOS to identify platform.
Based on progressive revisions of the leds-net5501 driver that
was rewritten by Ed Wildgoose as a platform driver.
Trivial platform driver for Soekris Engineering net5501 single-board
computer. Probes well-known locations in ROM for BIOS signature
to confirm correct platform. Registers 1 LED and 1 GPIO-based
button (typically used for soft reset).
