Given the mimimal hardware support for msm899(2/4) currently.
A few config options are needed to allow for continued
development and booting.

The following are needed for continued development and
booting:
  -InitRD support
  -8x74 pinctrl for serial support
  -Enable Global Glock Controller (gcc)

We already had BLK_DEV_INITRD, which I presume was sufficient.

Why do we need BLK_DEV_RAM, too?


BLK_DEV_RAM , has been removed as it turns out my buildroot ramdisk was the cause of this dependancy, it has been since updated. Everything works as expected with a slight change to my kernel cmdline,

'console=ttyMSM0,115200,n8 earlycon=msm_serial_dm,0xf991e000 loglevel=15 ddebug_query debug console=ttyMSM0,115200,n8'
