Hi llandre,

Did you have any success with your Cirrus Logic EDB93xx and 
cpu/arm920t/ep93xx???

My first attempt to do something like

$(LIB): $(OBJS)
	$(AR) crv $@ $(OBJS) imx/libimx.a

in cpu/arm920t/Makefile resulted in some error

My cpu/arm920t/imx/Makefile looks like

#########################################################################
include $(TOPDIR)/config.mk

LIB     = libimx.a

OBJS    = imx_generic.o imx_interrupts.o \
           imx_serial.o imx_speed.o

all:    .depend $(LIB)

$(LIB): $(OBJS)
         $(AR) crv $@ $(OBJS)

.depend:        Makefile $(OBJS:.o=.c)
                 $(CC) -M $(CFLAGS) $(OBJS:.o=.c) > $@

sinclude .depend
#########################################################################

which is pretty much like cpu/arm920t/Makefile...

But I suspect that creating an archive with another archive like

	$(AR) crv $@ $(OBJS) imx/libimx.a

goes wrong...

"arm_920TDI-nm imx/libimx.a" works fine. But "arm_920TDI-nm libarm920t.a" 
brings
...
00000188 T do_undefined_instruction
00000000 T enable_interrupts
          U memcpy
          U panic
          U printf
          U reset_cpu
00000048 T show_regs
arm_920TDI-nm: libimx.a: File format not recognized
