/* mstat.c: The mstat command is provided as a target-specific command for keeping track of various monitor-specific stuff... uart baud rate, malloc stats, chip-select configuration, etc... General notice: This code is part of a boot-monitor package developed as a generic base platform for embedded system designs. As such, it is likely to be distributed to various projects beyond the control of the original author.
