AM3352: JFFS2 mount time

Part Number: PROCESSOR-SDK-AM335X

I have custom board whose MCU is am3352. I am working on AM335xSDK08_00_00_00.

I am trying to boot linux system by using SPI Nor Flash and to make filesystem by using jffs2.

I find mount JFFS2 takes a lot of time（16M rootfs 21s）.

I tried to find some cases, but it didn't work. (  https://blog.csdn.net/lh2016rocky/article/details/54693248  )

I found that all the patch and sdk-08 codes did not match.

make menuconfig:

make Tools:

./mkfs.jffs2 -n -e 0x10000 -p 0x10000 -d ./filesystem -o gfsu.jffs2
./sumtool -n -e 0x10000 -p -i gfsu.jffs2 -o sum-gfsu.jffs2

Now, I need help to reduce the mount time of JFFS2 and the boot time.

Thank you！
