I'm sorry to bother you! I'm Hiep from Jinzai Solution (a Japanese Company). We are testing Linux kernel v4.0-rc2 on Lager and Koelsch Board (=20 Renesas's boards). When we tried to test QSPI-FLASH, we can't mount the device file of=20 QSPI-FLASH on Lager. (Koelsch has no problems) The logs is showed as below: #mount /dev/mtdblock2 /mnt/ "EXT3-fs (mtdblock2): error: can't find ext3 filesystem on dev mtdblock2. EXT4-fs (mtdblock2): VFS: Can't find ext4 filesystem EXT4-fs (mtdblock2): VFS: Can't find ext4 filesystem FAT-fs (mtdblock2): bogus number of reserved sectors FAT-fs (mtdblock2): Can't find a valid FAT filesystem FAT-fs (mtdblock2): bogus number of reserved sectors FAT-fs (mtdblock2): Can't find a valid FAT filesystem mount: you must specify the filesystem type" We found that, after removing this patch(as below), QSPI-FLASH can mount on Lager very well without any problems. "9064bf3=E3=80=80spi: spi-pxa2xx: only include mach/dma.h for legacy DMA" I'd like to report it to you and please review it when you have time. Best Regards, Jinso/Cao Minh Hiep.
