Yes placement could be improved. However, it is done on a per block basis, not byte, so the overhead isn't that noticeable. Spinning a wheel every 16k should not be that bad. (Its currently spinning at the page size instead of the block, but that could be easily changed).

Dear Richard,

Use common sense. The only thing it does is making a part of the code which takes more time than you like eveln slower: I'm not talking about the few CPU cycles for the printf (putc() would have been much simpler), but especially about trashing the cache for "pretty" things that don't add value, and the time it takes to output this stuff on a slow serial line.

the code I've talked with like such a feature. It seems that same bit of code has been replicated in a few places. Surly having a library call and some ifdef's would be acceptable.

No, not at this place. It's a different story when - for example - waiting for a flash sector be return to ready state when erasing it. Here you have to wait anyway, so feel free to implement this busy wait as you like it.

As far a code formatting, I'll see if I can't fix it up. I find myself using several editors depending on the context of what I'm doing. I've

mastered any of them... When I do the diff -purN for the patch, I

don't notice differences except in the areas I have changed something.

What

code reformatter/filter do you use? Some of the more recent u-boot

releases

have had a lot of style changes to the point I would suspect you ran something over the code.

vi and indent (indent -kr -i8 -bad -bap -nbc -br -c33 -cd33 -ncdb -ce -ci8 -cli0 -cp33 -d0 -di1 -nfc1 -nfca -i4 -ip0 -l75 -lp -pcs -npsl -nsc -nsob -nss -ts4, to be precise).
