- Global font_data_type
- Add support for fonts in regular ram
- Global pll_wait_for_lock (unsigned int pll_id)
- Use a timeout to avoid waiting forever and hanging the system
- Global sysclk_get_cpu_hz (void)
- This function assumes that the CPU always runs at the system clock frequency. We want to support at least two more scenarios: Fixed CPU/bus clock dividers (config symbols) and dynamic CPU/bus clock dividers (which may change at run time). Ditto for all the bus clocks.
- Global sysclk_get_main_hz (void)
- This function assumes that the main clock source never changes once it's been set up, and that PLL0 always runs at the compile-time configured default rate. While this is probably the most common configuration, which we want to support as a special case for performance reasons, we will at some point need to support more dynamic setups as well.
