Update the vw index in group setting. Here is the format.
|
|
< ESPI_NPCX_VW_EX_VAL(direction, group_number, index) >
|
|
direction: 1 for ESPI_CONTROLLER_TO_TARGET and 0 for ESPI_TARGET_TO_CONTROLLER.
|
|
group_number: The number of VWEVMS or VWEVSM.
|
|
index: The index to be replaced.
|
|
|
|
For example, update the index of VWEVMS6 into 0x4A and the index of VWEVSM8 into 0x53
|
|
vw-index-extend-set = < ESPI_NPCX_VW_EX_VAL(1, 6, 0x4A)
|
|
ESPI_NPCX_VW_EX_VAL(0, 8, 0x53) >
