I'm still not happy with that. What I had in mind was more or less:
static void output_char_serial(char c)
{
arm_pl011_write_polled(&pl011_context.base, c);
}
static void output_char_fb(char c)
{
fbcons_write_polled(&fb_context.base, c);
}
BSP_output_char_function_type BSP_output_char = output_char_serial;
And if you decide that the frame buffer should be used in the select
function you do a
BSP_output_char = output_char_fb;
