Just re-checked the C99 specs, and yes, all static scope vars must be 
initialized, so I stand corrected as for BSS initialization. I still 
think, though, that one should not count on a BSS-allocated variable to 
be zero at program start, and if one wants a variable to be zero, one 
must initialize it explicitly.

Anyway, as I said, the nand_chip[] issue is not, I believe, related to 
initializing BSS, as the writing and reading both occur after setting up 
the C environment for running from RAM.
