Frankly, if supporting large flash devices (or arrays) is an issue, then perhaps the wear-leveling intermediate layer with a standard filesystem on top is a better approach. The real issue with porting JFFS2 is that its covered by the GPL, and putting GPL code in the FreeBSD kernel is typically considered a 'no- no'. Still, the embedded linux folks get a >TON< of milage out of MTD+JFFS2. Nobody has brought up supporting non-Freesbie bootloaders, either. Many boards use redboot, u-boot or one of the MIPS loaders to get going. Getting these to boot FreeBSD will also be part of any solution. I don't think its practical to port Freesbie to any new board, not in the short-to-medium timeframe, either. JimReceived on Fri May 26 2006 - 00:37:53 UTC
