MTD UBI undefined reference failed to build OE gatesgarth branch

[Jupiter <jupiter.hce@gmail.com>]

Hi Tom and Lauren,

I failed to build mx6ull with MTD and UBI in OE and meta-freescahe
gatesgarth branch, please be aware that I was able to build it in zeus
branch, it seems something broken in gatesgarth branch.

My apology I am not clear if it is the issue for MTD or u-boot or
meta-freescale or OE so that I posted messages to several mailing
lists for help. Andrey Zhizhikin was very unhappy about it, he
believes it is your responsibility.

Could you please kindly respond if it is your jurisdiction and if you
tested and passed mx6ull with MTD UBI in gatesgarth branch or not?

My apology again for crossing mailing lists.

Kind regards,

- jupiter
