Anton Blanchard 747c96b100 Cut down hello_world to fit in 4kB 
Signed-off-by: Anton Blanchard <anton@linux.ibm.com>

Anton Blanchard bc4e6b7efe Reduce hello_world footprint to fit in 8kB 
When building with yosys we assume hello_world fits in 8kB. There's
enough free space that we can adjust the linker script to make it fit.

Benjamin Herrenschmidt e3941109af console: Cleanup console API 
Use a more generic console_init() instead of potato_uart_init(),
and do the same for interrupt control. There should be no
change in behaviour.

Benjamin Herrenschmidt c5f5f50738 hello_world: Use new headers and frequency from syscon 
This uses the new header files for register definitions and
extracts the core frequency from syscon rather than hard coding it.
