Is a SPI driver for FatFS available for SD cards greater than 4GB?

Can anyone tell me if a SPI driver exists to link with FATFs that supports SDHC/SDXC cards. i.e. greater than 4GB.

The examples supplied in the STCube only seems to support SDSC <4GB.

I see that clive1 has patched the SDIO example in the link below but I am looking for a SPI version.

If it doesn't exist then I will have to patch the existing example but I would obviously like to avoid this.

I am developing on the STM32F030R8-Discovery which uses the stm32_adafruit_sd.c driver to interface with the FATFs as starting point.
