Now our arm board is based on u-boot v2009.08 and I need to use

bifs.

So I replace some files from u-boot's latest version.

They are:

fs/ubifs/ubifs.c
fs/ubifs/ubifs.h
include/asm-arm/bitops.h
include/linux/bitops.h

and define the following configs in config file:

#define CONFIG_CMD_UBI
#define CONFIG_CMD_UBIFS
#define CONFIG_RBTREE
#define CONFIG_LZO

When compiling, I encountered an error:

<snip>

Is there any other files I need to merge to resolve this error?

Yes, there must be something missing. I just tried compiling UBIFS on ARM on the latest U-Boot version from the git repository. I used the "apollon" target and added the following defines:

#define CONFIG_CMD_UBIFS #define CONFIG_LZO

Works like a charm. No problems. I suggest you use the latest version of U- Boot version on your board as well.

Cheers, Stefan
