refactor(ulp): move ULP program Kconfig options to its components
The Kconfig options for the program running on the ULP coprocessor now live with the components that build it, not with the ULP coprocessor driver on the HP core. The driver sources them, so applications resolve them as before.

Set this option to route lp_core_printf to the console HP-UART.
|
||||
This allows you to easily view print outputs from the LP core, without
|
||||
having to connect to the LP-UART. This option comes with the following
|
||||
limitations:
|
||||
|
||||
1. There is no mutual exclusion between the HP-Core and the LP-Core accessing
|
||||
the HP-UART, which means that if both cores are logging heavily the output
|
||||
strings might get mangled together.
|
||||
2. The HP-UART can only work while the HP-Core is running, which means that
|
||||
if the HP-Core is in deep sleep, the LP-Core will not be able to print to the
|
||||
console HP-UART.
|
||||
|
||||
Due to these limitations it is only recommended to use this option for easy debugging.
|
||||
For more serious use-cases you should use the LP-UART.
