[PATCH v4] davinci: Add additional JTAG code for AM-1808 and OMAP-L138 Rev 2.0 SoCs

[Michael Williamson]

From: Sudhakar Rajashekhara <sudhakar.raj@ti.com>

The JTAG variant code for Rev-2.0 silicon of the OMAP-L138 has changed.
In addition, the variant code for the AM-1808 SoC appears to match
the Rev-2.0 code for the OMAP-L138.  Add an additional entry to support
these chips.

This patch is originally from a patch on the arago project, here:
http://arago-project.org/git/projects/?p=linux-omapl1.git;a=commit;h=6157618435e313a444cdf059702bd34036a6e2b7

http://linux.davincidsp.com/pipermail/davinci-linux-open-source/2010-November/021224.html

This patch was tested using an AM-1808 SoC on a MityARM-1808 SoM card.  It
was also tested using a Rev 1.0 silicon OMAP-L138 on a MityDSP-L138F card.

This should be a separate patch. Can you please drop this
change from this patch.

Thanks,
