This means there should be no reference to YAFFS2 in the upstream kernel? Because, I have located some defconfigs in upstream kernel where YAFFS2 support is enabled by default. ie: CONFIG_YAFFS_YAFFS2=y CONFIG_YAFFS_AUTO_YAFFS2=y in below listed files:
1. arch/arm/configs/msm_defconfig 2. arch/blackfin/configs/IP0X_defconfig 3. arch/blackfin/configs/SRV1_defconfig 4. arch/blackfin/configs/BlackStamp_defconfig 5. arch/blackfin/configs/BF533-EZKIT_defconfig 6. arch/arm/configs/cam60_defconfig 7. arch/blackfin/configs/BF538-EZKIT_defconfig 8. arch/blackfin/configs/BF533-STAMP_defconfig 9. arch/blackfin/configs/PNAV-10_defconfig 10. arch/blackfin/configs/BF537-STAMP_defconfig 11. arch/blackfin/configs/BF526-EZBRD_defconfig 12. arch/blackfin/configs/BF527-EZKIT_defconfig,
Please let me know your opinion on this.
