Subject: [PATCH] mount_root: fix jffs2 handling on MTD devices emulated by
|
||||
gluebi
|
||||
|
||||
The jffs2_ready() function in mount_root.c checks
|
||||
the presence of various JFFS2 markers at the start
|
||||
of a given MTD device. The function works on NOR
|
||||
flashes because JFFS2 puts 'cleanmarker' nodes at
|
||||
the start of freshly erased blocks.
|
||||
|
||||
However if jffs2 is used on a MTD device emulated
|
||||
by the gluebi layer, the 'cleanmarker' nodes are
|
||||
not present and the jffs2_ready() function fails.
|
||||
|
||||
Update the code to handle jffs2 correctly even on
|
||||
MTD devices emulated by the gluebi layer.
