Add s3c6400 support to the s3c2410 driver. The nand controller in
the s3c64xx devices is compatible with the one in the s3c2412, so
simply reuse that code.

This patch adds support to handle multiple non-identical chips in one
flash device tree node. It also adds concat support to physmap_of. This
makes it possible to support e.g. the Intel P30 48F4400 chips which
internally consists of 2 non-identical NOR chips on one die. Additionally
partitions now can span over multiple chips.
To describe such a chip's, multiple "reg" tuples are now supported in one
flash device tree node. Here an dts example:
flash@f0000000,0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "cfi-flash";
reg = <0 0x00000000 0x02000000
0 0x02000000 0x02000000>;
bank-width = <2>;
partition@0 {
label = "test-part1";
reg = <0 0x04000000>;
};
};

Add support for Samsung Flex-OneNAND devices.
Flex-OneNAND combines SLC and MLC technologies into a single device.
SLC area provides increased reliability and speed, suitable for storing
code such as bootloader, kernel and root file system. MLC area
provides high density and is suitable for storing user data.
SLC and MLC regions can be configured through kernel parameter.

Due to a processor anomaly (05000263 to be exact), most Blackfin parts
cannot keep the embedded filesystem image directly after the kernel in
RAM. Instead, the filesystem needs to be relocated to the end of memory.
As such, we need to tweak the map addr/size during boot for Blackfin
systems. This can be done in any early arch/board init code.

The DMAs have different bit sizes on BF52x and BF54x. From the PHRM:
"The 16-bit DMA Access Bus (DAB) connects the DMA controller to the
on-chip peripherals, PPI, SPI, Ethernet MAC, the SPORTs, NFC,
HOSTDP and the UARTs."
32-bit DMA won't work for BF52x.

Add optional callback to allow platform to initialize partitions.
Static partitions on a nand device could vary depending on the size of the
device. This patch allows an optional platform callback to be used to
setup this partition information at runtime.
Scan order is:
1) chip.part_probe_types
2) chip.set_parts
3) chip.partitions
4) full mtd device (fallback for no partitions)
Some of the existing nand drivers could possibly be replaced by the
plat_nand driver by using this patch. These include autcpu12.c and
ts7250.c drivers.

The RAMROOT function was a successful but non-portable attempt to append
the root filesystem to the end of the kernel image. The preferred and
portable solution is to use an initramfs instead.
The only user of this function was the msp71xx configuration
in the MIPS architecture; as the use of the RAMROOT has been removed
from that configuration, there are no more users, so this code
can be removed.
