[PATCHv2 0/4] Adding soc related info into /proc/cpuinfo

[Eduardo Valentin]

Hello all,

Here is the version 2 of this series. Now die id is protected using
same x86 protection mechanism to hide x86 product number. Besides,
a compilation Kconfig option has been added for DIE ID as well.

Here is previous PATCH 0/4 message:

This series is to continue what has been discussed several weeks ago
wrt IDCODE patch. Original patch was made by Peter and discussion is here:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg17553.html

So, the conclusion was that IDCODE info is useful even in production systems,
and for that debugfs is not a good choice to export it. One suggestion was to
add it under /proc/cpuinfo. However this entry nowadays exports only ARM related
information.

So this series does the trick by extending the ARM /proc/cpuinfo to include
soc info data. There are a few ways to add a hook for soc specific data. But
I've decided to implement it via the simplest way I found. Basically it is
same thing which is done for system_rev, system_serial_low and system_serial_high.
Then, now we have system_soc_info, which is printed only if there is something
useful there.

As usual, comments are welcome.

BR,
