[U-Boot-Users] [PATCH] ppc_4xx resubmit: netstal/common define routines used by all boards
Niklaus Giger
niklaus.giger at netstal.com
Wed Jan 16 18:39:19 CET 2008
Added some routines used by all Netstal boards:
- nm_bsp.c: - nm_show_print and
- common_misc_init_r
- set_params_for_sw_install. Bery specific code to handle our SW
installation procedure
- fixed_sdram.c: Common routines for HCU4 (and upcoming) MCU25 boards
to handle sdram initialization.
- nm.h: Common header
