I just wonder what is worse, having code in there that is labelled
da850 but not tested on all devices of the family, or having it
renamed every time someone finds out that it also runs on other
devices. TI uses a common PLL initialization code in its User Boot
Loader (UBL) for OMAP-L138, DA850, AM180x, so it should be pretty save
to rename it right now.

Did you also read the rest of my last email, the PSC part?

Regards, Christian
