another simple clarification -- i realize that a lot of the source files of the form common/cmd_*.c might contain more than just the command code, they might contain infrastructure code that's necessary apart from the commands themselves.

but in the case of cmd_reginfo.c, this code at the very end:

#if defined(CONFIG_CMD_REGINFO) U_BOOT_CMD( reginfo, 2, 1, do_reginfo, "print register information", "" ); #endif

it seems that that preprocessor check is superfluous since the entire file is nothing more than the implementation of the "reginfo" command, and the relevant test is already being done in the Makefile:

COBJS-$(CONFIG_CMD_REGINFO) += cmd_reginfo.o

am i understanding that correctly? thanks.
