CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be some end address; to make the meaning more clear we rename it into CONFIG_SYS_INIT_RAM_SIZE No other code changes are performed in this patch, only minor editing of white space (due to the changed length) and the comments was done, where noticed. Note that the code for the PATI and cmi_mpc5xx board configurations looks seriously broken.
