how to access jffs2 partition properties?

[Robert P. J. Day]

  on a PPC system using a 2.4.22 kernel, is there a way to access the
properties for the jffs2 filesystems that have been defined on the two
flash chips this system has?

  it's easy enough to see the devices /dev/mtdblock/[0-4] that
represent the partitions, and the file /proc/partitions contains:

  31     0         64 mtdblocka
  31     1        384 mtdblockb
  31     2        128 mtdblockc
  31     3       3072 mtdblockd
  31     4      29184 mtdblocke

but can i examine, for each of these, its chip, starting address,
ending address, etc?  thanks.
