# Serial Port Library backed by SBI console.
|
|
#
|
|
# Meant for SEC and PEI (XIP) environments.
|
|
#
|
|
# Due to limitations of SBI console interface and XIP environments
|
|
# (on use of globals), this library instance does not implement reading
|
|
# and polling the serial port. See PrePiDxeSerialPortLibRiscVSbiRam.inf
|
|
# for the full-featured variant meant for PrePi and DXE environments.
