[U-Boot] [PATCH 0/2] omap3: Optimize detection of cpu revision

Each call to get_cpu_rev() leads to repetitive
execution of code to detect the cpu revision.

This patchset ensures that mechanism to detect
revision is not executed each time; instead a
stored value is returned.

Since, revision info is needed in s_init(),
the function to identify cpu revision needs
to be called twice. At the moment, it is
necessary/ unavoidable.
