Dear Michal,
Cc: Geert,
I've tested the linux v4.10-rc2 for Gen2 Lager and found an issues when
writing data to SPI-FLASH with jffs2 format
"root@linaro-naro:~# cp test.dat /mnt/media
[ 223.874078] ------------[ cut here ]------------

Please have a look at the attached testlog file for detail.
And I found the patch which I think it is the cause of this issues.
The commit name is 'e5d05cb mtd: spi-nor: simplify write loop'
If I reverted this patch and retested it on H2 board, the issue will be
gone!
Regards,
Dong
