![David Brownell](/assets/img/avatar_default.png)
Move the clock-rate dumping code into the cpu/.../davinci area where it should have been, enabled by CONFIG_DISPLAY_CPUINFO, updating the format and showing the DSP clock (where relevant). Switch boards to use the cpuinfo() hook for this stuff. Remove a few now-obsolete PLL #defines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
