Title:
  Configuration option error for ARM in default-configs

Status in QEMU:
  Fix Released

Bug description:
  The problem occurs when I try to launch qemu-system-arm for the machine: 
lm3s6965evb (Stellaris LM3S6965EVB)
  The error message was:  qemu: hardware error: Unknown device 'ssd0323' for 
bus 'SSI'

  The error message means that the LED display driver (SSD0323) of the
  LM3S6965 evaluation board isn't recognised.

  Searching through the source code of QEMU 0.12.3, I've seen in 
default-configs/arm-softmmu.mak that there is reference
  made to: 
  CONFIG_SD0303=y
  CONFIG_SD0323=y

  These parameters in turn are evaluated in the Makefile, as
  obj-$(CONFIG_SSD0303) += ssd0303.o
  obj-$(CONFIG_SSD0323) += ssd0323.o

  The problem is that the spelling of the tags doesn't match up:
  CONFIG_SD0303 in the .mak vs CONFIG_SSD0303 in the Makefile (double
  SS)

  Furthermore, in arm-softmmu.mak, reference is made to CONFIG_LAN9118=y
  and CONFIG_SMC91C111=y, which isn't referenced by the Makefile at all.

  Please correct these parameters in default-configs/arm-softmmu.mak in
  order to give full functionality to the ARM Cortex M3 evaluation
  boards.
