Select this option to enable SPI DMA support.
# The LPC SPI DMA controller requires the source and destination to be 64 byte
# aligned.

Select this option if platform supports eSPI using D14F3 configuration
registers.

help
SMU will lock up at times if the port80h enable bit is cleared. Select
this option to retain the port80 enable bit while clearing other enable
bits in the ESPI Decode register.
