ARM: SoC: late updates

Browse source 
A few updates that we merged late but are low risk for regressions for
 other platforms (and a few other straggling patches):
 
  - I mis-tagged the 'drivers' branch, and missed 3 patches. Merged in
    here. They're for a driver for the PL353 SRAM controller and a build
    fix for the qualcomm scm driver.
  - A new platform, RDA Micro RDA8810PL (Cortex-A5 w/ integrated Vivante
    GPU, 256MB RAM, Wifi). This includes some acked platform-specific
    drivers (serial, etc). This also include DTs for two boards with this
    SoC, OrangePi 2G and OrangePi i86.
  - i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K
    video playback offload). This is the first i.MX 64-bit SoC.
  - Some minor updates to Samsung boards (adding a few peripherals in
    DTs).
  - Small rework for SMP bootup on STi platforms.
  - A couple of TEE driver fixes.
  - A couple of new config options (bcm2835 thermal, Uniphier MDMAC)
    enabled in defconfigs.

Device tree bindings for ARM PL353 static memory controller
PL353 static memory controller supports two kinds of memory
interfaces.i.e NAND and SRAM/NOR interfaces.
The actual devices are instantiated from the child nodes of pl353 smc node.
Required properties:
- compatible : Should be "arm,pl353-smc-r2p1", "arm,primecell".
- reg : Controller registers map and length.
- clock-names : List of input clock names - "memclk", "apb_pclk"
(See clock bindings for details).
- clocks : Clock phandles (see clock bindings for details).
- address-cells : Must be 2.
- size-cells : Must be 1.
Child nodes:
For NAND the "arm,pl353-nand-r2p1" and for NOR the "cfi-flash" drivers are
supported as child nodes.
for NAND partition information please refer the below file
Documentation/devicetree/bindings/mtd/partition.txt
Example:
smcc: memory-controller@e000e000
compatible = "arm,pl353-smc-r2p1", "arm,primecell";
clock-names = "memclk", "apb_pclk";
clocks = <&clkc 11>, <&clkc 44>;
reg = <0xe000e000 0x1000>;
#address-cells = <2>;
#size-cells = <1>;
ranges = <0x0 0x0 0xe1000000 0x1000000 //Nand CS Region
0x1 0x0 0xe2000000 0x2000000 //SRAM/NOR CS Region
0x2 0x0 0xe4000000 0x2000000>; //SRAM/NOR CS Region
nand_0: flash@e1000000 {
compatible = "arm,pl353-nand-r2p1"
reg = <0 0 0x1000000>;
(...)
};
nor0: flash@e2000000 {
compatible = "cfi-flash";
reg = <1 0 0x2000000>;
};
nor1: flash@e4000000 {
compatible = "cfi-flash";
reg = <2 0 0x2000000>;
};
};

RDA Micro UART
Required properties:
- compatible : "rda,8810pl-uart" for RDA8810PL SoCs.
- reg : Offset and length of the register set for the device.

Example:
uart2: serial@20a90000 {
compatible = "rda,8810pl-uart";
reg = <0x20a90000 0x1000>;
interrupts = <11 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&uart_clk>;
