uboot阶段注释掉CONFIG_DISP2_SUNXI后，启动log会卡住。

mangogeek LV 8

环境：1.0.1 tina-d1-open

在运行OK的代码基础上，只将uboot下configs里的 sun20iw1p1_defconfig 中 CONFIG_DISP2_SUNXI 注释掉，方法参考自：（ D1_Tina_linux_LCD_调试指南.pdf p70）。
启动log会卡到如下位置：

[    2.520958] sunxi-spinand-phy: ========== logical info ==========

后卡住不动。

正常系统应该继续如下打印：
