After discussed with the colledgue responsor for GDB and ptrace utils, we will fix this in Linux kernel later.
Ans, I'll fix it in the next patch v8.

The typedef struct bd_info comes from arch/i386/include/asm/u-boot.h
and arch/arm/include/asm/u-boot.h.

If you grep the author "Marius Groeger <mgroeger at sysgo.de>" then you can find the
the 2 files were in the grep result which was originally referenced.
Hence we put (C) listed above because we have referenced those 2 files.

If you have any suggestion, please let me know.
