[U-Boot] [PATCHv2] check u-boot SPL size to avoid producing non-working images

[Pavel Machek]

Debugging SPL is hard, and if SPL is too big, it tends to crash in
mysterious ways.

(I'm not sure what the exact threshold is, 49762 bytes works, 52426
bytes does not, so 50000 should be good value).

Ok, that's simple enough. It computes the size different way, thus the
different number.
