Create SOC IP block information database

; Summary: Create SOC IP block information database

; Proposer: Tim Bird (for EL summit attendees)

== Description ==
SOC products consists of general-purpose CPUs along with a variety of
additional blocks of functionality. During the chip design phases,
these additional blocks of functionality are called "IP blocks", and
the source code to create them is often licensed or bought from external
suppliers. Some examples include the ethernet PHYs (circuit definitions to
define ethernet hardware functionality), serial ports, audio components,
generic digital signal processors, codec processors, and graphics processing
units.

Often, these IP blocks are reused from one SOC product to another. Also,
these IP blocks are sometimes modified by the supplier or SOC vendor, over
time.

When writing Linux kernel driver software for a new SOC, it can be helpful to know
the specific IP block (and it's heritage) used in a chip, in order to
reuse software from other projects.

This project would consist of creating and maintaining an SOC IP Block information
database. It is proposed to keep the information on the elinux wiki, to be a
publicly available resource for those working on driver support for SOCs.

== Related work ==
Chip vendors sometimes supply spec sheets for their parts. However, while these
sheets may list technical details about the functionality of a chip, they often
omit the source of an IP block source or it's heritage, which is useful for
writing a driver for the block.

== Scope ==
I'm going to guess that a first-order database of the top 50 IP blocks used
in current SOCs would take about 2 months to assemble and document.

== Contractor Candidates ==
None - someone with a hankering for misery.
