When using the eSPI peripheral channel for HOST_CMD, the STS0 bit indicates that EC is busy. To reflect this properly, STS0 should only be set when there is actual input data to process. This avoids falsely signaling a busy state when there is no data. Signed-off-by: Elmo Lan <[email protected]>

There was a problem hiding this comment.
wouldn't this IB data invalid if IBF is not set?
in that case shouldn't this data copy code moved under above if condition?
