- Enable support for USI block. USI (Universal Serial Interface) is an
- IP-core found in modern Samsung Exynos SoCs, like Exynos850 and
- ExynosAutoV9. USI block can be configured to provide one of the
- following serial protocols: UART, SPI or High Speed I2C.
- This driver allows one to configure USI for desired protocol, which
- is usually done in USI node in Device Tree.

- Enable the PM code's memory area checksum over sleep. This option

- going to sleep. The blocks are then checked on resume for any

- Set the chunksize in Kilobytes of the CRC for checking memory
- corruption over suspend and resume. A smaller value will mean that
- the CRC data block will take more memory, but will identify any
- faults with better precision.
