Does STM32F429 support SPI RGB Serial Interface?

I found a LCD with OTA5182A driver in SPI & RGB interface. However its RGB is serial RGB not parallel RGB in STM32F429. Is there a way to allow the LCD controller to work with STM32F429 inside lcd display?

So it goes back to just a standard interfacing problem:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

The STM32's SPI neither knows nor cares anything about the meaning of the data it transfers - so you can program it to carry whatever data you like!

The problem is that serial RGB has only 8-bit data line, the parallel has 3*8 data lines. The LCD control will be different. The Discovery board connected 24 data lines from LCD display. And there is no frame buffer (RAM) in serial RGB LCD display.
