#  The Lattice Mico32 port uses the system_config.h generated by the Mico
#  System Builder to retrieve the properties of the peripherals.
#
#   Implemented (in shared/ subdirectory)
#     Polled console driver (uart)
#     Clock interrupt with 10 ms tick
#     Networking using Lattice tri-speed ethernet MAC
#
#   Todo
#     Support more peripherals:
#       - uart driver using interrupts

To on the simulator included in lm32-gdb use these commands:

tar sim --hw-device lm32cpu \
  --hw-device "lm32uart/reg 0x80006000 0x100" \
  --hw-device "/lm32uart > int int0 /lm32cpu" \
  --hw-device "lm32timer/reg 0x80002000 0x80" \
  --hw-device "/lm32timer > int int1 /lm32cpu" \
  --memory-region 0x08000000,0x4000000
load

The simulator is VERY VERY slow when RTEMS is idle.
To speed this up, add SIMULATOR_FAST_IDLE=1 to the
configure command.
