#
# MBX8xx-specific options:
#
# UARTS_USE_TERMIOS
# Define to 1 if you want termios support for every port.
# Termios support is independent of the choice of UART I/O mode.
#
# CONSOLE_MINOR (BSP--console driver)
# Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
# SCC3_MINOR, or SCC4_MINOR. Determines which device will be registered
# as /dev/console.
#
# UARTS_USE_INTERRUPTS (BSP--console driver)
# Define if you want interrupt-driven I/O instead of polling. Superceeded
# by EPPCBUG_SMC1 on SMC1.
# UARTS_IO_MODE (BSP--console driver)
# Define to 0 if you want polled I/O performed by RTEMS.
# Define to 1 if you want interrupt-driven performed by RTEMS.
# Define to 2 if you want polled I/O performed by EPPCBug.
# There is no provision to have a mix of interrupt-driven and polled I/O
# ports, except that the printk port may use a different mode from the
# other ports. If this is done, do not open the printk port from an RTEMS
# application. With EPPCBug 1.1, if mode 2 is selected, CONSOLE_MINOR must
# be set to SMC1_MINOR. This is a deficiency of the firmware: it does not
# perform serial I/O on any port other than its default debug port, which
# must be SMC1.
#
# PRINTK_MINOR (BSP--console driver)
# Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
# SCC3_MINOR, or SCC4_MINOR. Determines which device is used for output
# by printk(). If the port that printk() uses is also used for other I/O
# (e.g. if PRINTK_MINOR == CONSOLE_MINOR), then both ports should use
# the same type of I/O, otherwise the drivers will likely conflict with
# each other.
#
# PRINTK_IO_MODE (BSP--console driver)
# Define to 0 if you want polled I/O performed by RTEMS.
# Define to 1 if you want interrupt-driven I/O performed by RTEMS.
# Define to 2 if you want polled I/O performed by EPPCBug.
# The printk() port is not configured to termios. The only way to
# use printk() with interrupt-driven I/O, which always uses termios,
# is to open the printk port from an RTEMS application. One way to
# do this is to have PRINTK_MINOR == CONSOLE_MINOR. With EPPCBug 1.1,
# if mode 2 is selected, PRINTK_MINOR must be set to SMC1_MINOR.
# This is a deficiency of the firmware: it does not perform serial I/O
# on any port other than its default debug port, which must be SMC1.
#
# EPPCBUG_SMC1 (BSP--console driver)
# If defined, the I/O through the SCM1 is done through the EPPCBug firmware.
# Because of limitations in revision 1.1 of the firmware, EPPCBug must be
# configured to use SMC1 as its console. If not defined, I/O through SMC1
# is done through a RTEMS device driver.
# If defined, SMC1 is in use by EPPC-Bug. The console driver will not
# re-initialize that port.
#
# EPPCBUG_VECTORS (BSP--RTEMS)
# If defined, the most vectors branch to EPPCBug, except the following:
# If defined, vectors branch to EPPCBug, except the following:
# 0x500 (external interrupt), 0x900 (decrementer).
