JFFS2 issue on flash on AMD flash

[Kasturi Raghunath]

Hi
  We are using AMD flash 29LV128 and flash type is Mirror Bit on our custom
board. The flash size is 32 M and bus width is 32 bit wide. I have ported
May 27 2004 snapshot of JFFS2 on my 2.4.7 timesys linux. When kernel boots
up JFFS2 prints lot of errors:

Linux/PPC load: wdt=1 console=ttyS0,9600 root=/dev/mtdblock/1 panic=1
mem=120M

Now booting the kernel
