Sergei Shtylyov	ca7d8b980b	memory: add Renesas RPC-IF driver Add the memory driver for Renesas RPC-IF which registers either SPI or HyperFLash device depending on the contents of the device tree subnode. It also provides the absract "back end" device APIs that can be used by the "front end" SPI/MTD drivers to talk to the real hardware.

memory: add Renesas RPC-IF driver

Add the memory driver for Renesas RPC-IF which registers either SPI or
HyperFLash device depending on the contents of the device tree subnode.
It also provides the absract "back end" device APIs that can be used by
the "front end" SPI/MTD drivers to talk to the real hardware.

memory: move jedec_ddr.h from include/memory to drivers/memory/

Now that jedec_ddr_data.c was moved from lib/ to drivers/memory/,
<memory/jedec_ddr.h> is included only from drivers/memory/.

Make it a local header of drivers/memory/.

The directory include/memory is now gone.

While I am here, I also changed #include <linux/module.h> to
<linux/export.h>. Because CONFIG_DDR is bool, jedec_ddr_data.c is
never compiled as a module.

ddr: add LPDDR2 data from JESD209-2

add LPDDR2 data from the JEDEC spec JESD209-2. The data
includes:

1. Addressing information for LPDDR2 memories of different
   densities and types(S2/S4)
2. AC timing data.

This data will useful for memory controller device drivers.
Right now this is used by the TI EMIF SDRAM controller
driver.
