The old build system had a bsp-post-link hook, so this is not really something new. > > Is there a ticket with requirements for this proposed change? > > An existing ticket exists (https://devel.rtems.org/ticket/4272) for a GSoC > project that defines a different approach where the conversion is held in the > eco-system depending on data installed with the BSP. The approach is not that much different. The BSP installs an optional Python script.

The BSP knows best how to provide a proper boot image which could depend on its BSP options (for example, memory locations).

My driving factor for this stuff is that I would like to have U-Boot images for test runs. -- embedded brains GmbH & Co.
