a156c47e39ad: tftp: prevent overwriting reserved memory
tftp with loadaddr is failing for Images of the size bigger than SPL. The issue is that SPL image is located at bootaddr and dtb is allocated at bootaddr + spl_size.
The region where dtb is present is marked reserved.
So when the tftp tries to load the Image it tries to find a location from loadaddr to the first reserved memory region which is the dtb base address. The max_size obtained is pretty less and hence tftp fails with the below error:
TFTP error: trying to overwrite reserved memory...
I don't quite get this. Are you saying that we load U-Boot to loadaddr, overwriting the SPL DT?
Simon Goldschmidt, any thoughts?

I am sure there are better solutions so just wanted to know if there is one.
