[PATCH 1/1] omap2/3: Update revision identification

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
