[U-Boot] [BUG] booting on the Tinker Board (tinker-rk3288_defconfig) is broken

[David Wu]

Hi Heinrich and Michael,

Another thing i see is that I missed a patch, for the 3288 gpio0, its
iomux is special, there is no high 16-bit write-enabled bit. For Tinker
board, it uses I2C0, the current driver will overwrite the I2C0 iomux,
while request the GPIO0A4. It requires a patch:
