Hi,
while porting an ATSAMA5D2 based board (booting from NAND flash with UBI)
I stumbled over generic, NAND- and UBI related asperity:
1. tiny-printf does not handle NULL arguments to '%s' in a proper way
2. vtbl_check() has an useless debug output due to a typo
3. NAND: An informative output fails badly, if the NAND vendor is unknown
4. the nand_atmel driver lacks a vital initialisation
OK, you might say the nand_atmel NAND driver is obsolete, but it was the
only solution to get booting from NAND running. The new DM based NAND driver
refused to do anything usefull, so I dropped it after spending a couple of
days debugging it:
<RANT>brilliant!</RANT>
