[David Woodhouse]

Update of /home/cvs/mtd/fs/jffs2/ecos/cdl
In directory phoenix.infradead.org:/tmp/cvs-serv17208/cdl

Modified Files:
	jffs2.cdl 
Log Message:
Read-only CDL option for JFFS2. With just enough ifdefs in fs-ecos.c to 
let function-sections and gc-sections throw away all the write code. 
Also no longer remove -Wpointer-arith from CFLAGS, and really disable the 
gcthread code.
