Makefile hierarchy: CFLAGS override-ability actually works now The original version was broken in that CFLAGS=${CFLAGS} passing was done without quotes, which breaks as soon as there is a space in the user-set CFLAGS. Changing it to CFLAGS="${CFLAGS}" makes it work as originally intended.

#include "types.h"

void
cmd_dieid()
{
	u32 addr;

	for (addr = 0xFFFEF010; addr <= 0xFFFEF016; addr += 2)
		printf("%08X: %04X\n", addr, *(volatile u16 *)addr);
}
