Minimum/optimal sector_size for jffs2

[Peter Menzebach]

Hi,
since my grep through the source code was not successful:
Is there a minimum possible jffs2_sb_info.sector_size and somewhere a 
definition?

Is there somewhat like an optimal sector_size?

I have here a device (dataflash), which has a very small
erase/write page size (1056 bytes).

Best regards
Peter
