mainboard/facebook/fbg1701: Configure TC358860 eDP to MIPI controller
FBG1701 contains a TC358860 eDP to MIPI Bridge controller which needs
to be configured.
Add mainboard_configure_edp_bridge() to program the controller.
CPLD version is used to determine which table must be programmed.
The eDP is an i2c slave which expects the next i2c bus data for block
write:
<Slave Addr> <Reg Addr[15:8]> <Reg Addr[7:0]> followed by data with LSB
first.
BUG=N/A
TEST=Config eDP and verify LCD panels are working on Facebook FBG-1701
