Some SDHCI IP can be synthetized in various endianness: https://github.com/u-boot/u-boot/blob/v2021.04/doc/README.fsl-esdhc
- CONFIG_SYS_FSL_ESDHC_BE
ESDHC IP is in big-endian mode. Accessing ESDHC registers can be determined by ESDHC IP's endian mode or processor's endian mode.
Our current implementation is little-endian. In order to support big endianness:
- Rename current MemoryRegionOps as sdhci_mmio_le_ops ('le') - Add an 'endianness' property to SDHCIState (default little endian) - Set the 'io_ops' field in realize() after checking the property - Add the sdhci_mmio_be_ops (big-endian) MemoryRegionOps.
