Building leon3 prom image for testing on renode

[Muhammad Sulthan Mazaya]

Hi Alan,

without a prom image. Is it that the RTEMS LEON3 BSP relies on
initialization done by the boot prom (GRMON or MKPROM2 based boot code)?

Do you or anyone on the devel mailing list know where/how can I check which
kind of initialization rtems leon3 bsp rely on? Sorry, I am fairly new to
this

Thank you,
Mazaya
