I have just updated that repo with my latest version. u-boot bsp is updated too. I tested fit some
month ago when was really new thing but I personally not add it to my workflow.
I am compiling generic platform with FIT support but not test it.


 If it would help, I can attach (or send) my project

If you have edk project, I can take a look or try to generate files.
(If you want send it to me in private email and not to bother u-boot mailing list)
Sorry I don't have a 1GB CF and time to debug it just for fun. I had one project in past
with systemace and CF and I had no problem to list/use both partitions.

this code can't be compiled - you have bad setting. MONITOR_BASE is always on lower address then
FLASH address. Check that your ram on lower address than your flash - this is check by u-boot.bsp too.

top bsp looks at bsp folder in hardware project, then all ModuleSearchPath which
are in xmp files and then take a look to edk patch for standalone bsp.
EDK user repository are in xmp as ModuleSearchPatch and bsp there should be used.
