Dear Minkyu Kang,

This should not be handled separately, but rather be squashed into the
patch that now creates the problem, i. e.

04/15 Chander Kashyap    [U-Boot] [PATCH] S5P:SROM config code moved to s5p-common directory
             http://article.gmane.org/gmane.comp.boot-loaders.u-boot/97781


Best regards,

Wolfgang Denk
