Subject: omap2/3: Update revision identification
X-Git-Tag: firefly_0821_release~7613^2~3644^2~26^3~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=76abab213587bfc3b850f36c0a674116d161148d;p=firefly-linux-kernel-4.4.55.git

omap2/3: Update revision identification

The existing definitions for cpu revision used
upper nibble in the bits[15:08]. With OMAP3630,
definitions use lower nibble.

This patch unifies the definitions to start
at lower nibble.
