a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

899d13d0df cbfs: new API and better program loading
A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.

All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.

The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

6114c99d12 ipq806x: load and start RPM
This patch finds the RPM image in the CBFS, loads it as defined by the
MBN header and signals to the RPM processor where the image is
located and waits for confirmation of the RPM starting.

The interactions with the RPM processor are copied as is from the
vendor provided sample code.

Debug messages added to help identify problems with loading the blobs,
should they ever happen.

08f249e7d0 ipq806x: Load TZBSP blob from coreboot ramstage
Read the TZBSP blob from CBFS and run it. A side effect of the blob
execution is switching the processor into User mode.

Starting TZBSP requires processor running in Supervisor mode, TZBSP
code is compiled for ARM. Coreboot is executing in System mode and is
compiled for Thumb. An assembler wrapper switches the execution mode
and interfaces between Thumb and ARM modes.

  With the preceeding patches the system successfully loads to
