sorry, I sent attach git format-patch directly, it cause the mistake mail, the patch is below. The SPL(bl2) is still the old one from manufacturer, as I don't know how to build a new one. I don't know much debug method, the how to use JTAG of it. Could anyone teach me some of it? Thanks. [PATCH] board: Fix mmc pins and remove some no use gpio.

In my board, the sdcard is in mmc2, and using sd2_cdn to detect. --- board/samsung/tiny4412/tiny4412.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-)
