reginfo command is calling mpc8xx_reginfo(), mpc85xx_reginfo() or mpc86xx_reginfo() based on CONFIG_ symbol. As those 3 functions can't me defined at the same time, let's rename them print_reginfo() to avoid the #ifdefs The name is kept generic as it is not at all dependent on powerpc arch and any other arch could want to also print such information. In addition, as the Makefile compiles cmd/reginfo.c only when CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD definition inside a #ifdef CONFIG_CMD_REGINFO Lets all remove the #ifdefs around the U_BOOT_CMD as this file is only compiled when CONFIG_CMD_REGINFO is defined Finally, this is a PowerPC-only command, disable it on a number of non-PowerPC platforms.
