2This file contains basic information on the port of U-Boot to IPHASE4539
3(Interphase 4539 T1/E1/J1 PMC Communications Controller).
4All the changes fit in the common U-Boot infrastructure, providing a new
5IPHASE4539-specific entry in makefiles. To build U-Boot for IPHASE4539,
6type "make IPHASE4539_config", edit the "include/config_IPHASE4539.h"
7file if necessary, then type "make".
