True, but so far they didn't overflow this limit I believe. Some of them are hanging on the verge of blowing it though, good point.

I think that a point to consider is if all scripts are already provided or we let the user/owner of the board to add his own scripts, as I presume. It is pity if he cannot do what u-boot really supports only to save some bytes.

It is pity if he cannot do what u-boot really supports only to save some bytes. I think this is more than enough to justify a bigger buffer. -- Otavio Salvador O.S.
