SoC platform removal 

There are a lot of platforms that have not seen any interesting code
 changes in the past five years or more.
 
 I made a list and asked around which ones are no longer in use [1], and
 received confirmation about six ARM platforms and the TI C6x architecture
 that have all reached the end of their life upstream, with no known
 users remaining:
 
  - efm32 -- added in 2011, first Cortex-M, no notable changes after 2013
  - picoxcell -- added in 2011, abandoned after 2012 acquisition
  - prima2 -- added in 20111, no notable changes since 2015
  - tango -- added in 2015, sporadic changes until 2017, but abandoned
  - u300 -- added in 2009, no notable changes since 2013
  - zx --added in 2015 for both 32, 2017 for 64 bit, no notable changes
  - arch/c6x -- added in 2011, but work stalled soon after that
 
 A number of other platforms on the original list turned out to still
 have users. In some cases there are out-of-tree patches and users
 that plan to contribute them in the future, in other cases the code
 is complete and works reliably.

Device State Configuration Registers
------------------------------------
TI C6X SoCs contain a region of miscellaneous registers which provide various
function for SoC control or status. Details vary considerably among from SoC
to SoC with no two being alike.
In general, the Device State Configuration Registers (DSCR) will provide one or
more configuration registers often protected by a lock register where one or
more key values must be written to a lock register in order to unlock the
configuration register for writes. These configuration register may be used to
enable (and disable in some cases) SoC pin drivers, select peripheral clock
sources (internal or pin), etc. In some cases, a configuration register is
write once or the individual bits are write once. In addition to device config,
the DSCR block may provide registers which are used to reset peripherals,
provide device ID information, provide ethernet MAC addresses, as well as other
miscellaneous functions.
For device state control (enable/disable), each device control is assigned an
id which is used by individual device drivers to control the state as needed.
Required properties:
- compatible: must be "ti,c64x+dscr"
- reg: register area base and size
Optional properties:
NOTE: These are optional in that not all SoCs will have all properties. For
SoCs which do support a given property, leaving the property out of the
device tree will result in reduced functionality or possibly driver
failure.
- ti,dscr-devstat
offset of the devstat register
- ti,dscr-silicon-rev
offset, start bit, and bitsize of silicon revision field
- ti,dscr-rmii-resets
offset and bitmask of RMII reset field. May have multiple tuples if more
than one ethernet port is available.
- ti,dscr-locked-regs
possibly multiple tuples describing registers which are write protected by
a lock register. Each tuple consists of the register offset, lock register
offsset, and the key value used to unlock the register.
- ti,dscr-kick-regs
offset and key values of two "kick" registers used to write protect other
registers in DSCR. On SoCs using kick registers, the first key must be
written to the first kick register and the second key must be written to
the second register before other registers in the area are write-enabled.
- ti,dscr-mac-fuse-regs
MAC addresses are contained in two registers. Each element of a MAC address
is contained in a single byte. This property has two tuples. Each tuple has
a register offset and four cells representing bytes in the register from
most significant to least. The value of these four cells is the MAC byte
index (1-6) of the byte within the register. A value of 0 means the byte
is unused in the MAC address.
- ti,dscr-devstate-ctl-regs
This property describes the bitfields used to control the state of devices.
Each tuple describes a range of identical bitfields used to control one or
more devices (one bitfield per device). The layout of each tuple is:
start_id num_ids reg enable disable start_bit nbits
Where:
start_id is device id for the first device control in the range
num_ids is the number of device controls in the range
reg is the offset of the register holding the control bits
enable is the value to enable a device
disable is the value to disable a device (0xffffffff if cannot disable)
start_bit is the bit number of the first bit in the range
nbits is the number of bits per device control
- ti,dscr-devstate-stat-regs
This property describes the bitfields used to provide device state status
for device states controlled by the DSCR. Each tuple describes a range of
identical bitfields used to provide status for one or more devices (one
bitfield per device). The layout of each tuple is:
start_id num_ids reg enable disable start_bit nbits
Where:
start_id is device id for the first device status in the range
num_ids is the number of devices covered by the range
reg is the offset of the register holding the status bits
enable is the value indicating device is enabled
disable is the value indicating device is disabled
start_bit is the bit number of the first bit in the range
nbits is the number of bits per device status
- ti,dscr-privperm
Offset and default value for register used to set access privilege for
some SoC devices.
Example:
device-state-config-regs@2a80000 {
compatible = "ti,c64x+dscr";
reg = <0x02a80000 0x41000>;
ti,dscr-devstat = <0>;

External Memory Interface
-------------------------

C6X Interrupt Chips
-------------------
* C64X+ Core Interrupt Controller
The core interrupt controller provides 16 prioritized interrupts to the
C64X+ core. Priority 0 and 1 are used for reset and NMI respectively.
Priority 2 and 3 are reserved. Priority 4-15 are used for interrupt
sources coming from outside the core.
Required properties:
--------------------
- compatible: Should be "ti,c64x+core-pic";
- #interrupt-cells: <1>
Interrupt Specifier Definition
------------------------------
Single cell specifying the core interrupt priority level (4-15) where
4 is highest priority and 15 is lowest priority.
Example
-------
core_pic: interrupt-controller@0 {
interrupt-controller;
#interrupt-cells = <1>;
compatible = "ti,c64x+core-pic";
};
* C64x+ Megamodule Interrupt Controller
The megamodule PIC consists of four interrupt mupliplexers each of which
combine up to 32 interrupt inputs into a single interrupt output which
may be cascaded into the core interrupt controller. The megamodule PIC
has a total of 12 outputs cascading into the core interrupt controller.
One for each core interrupt priority level. In addition to the combined
interrupt sources, individual megamodule interrupts may be cascaded to
the core interrupt controller. When an individual interrupt is cascaded,
it is no longer handled through a megamodule interrupt combiner and is
considered to have the core interrupt controller as the parent.
Required properties:
--------------------
- compatible: "ti,c64x+megamod-pic"
- interrupt-controller
- #interrupt-cells: <1>
- reg: base address and size of register area
- interrupts: This should have four cells; one for each interrupt combiner.
The cells contain the core priority interrupt to which the
corresponding combiner output is wired.
Optional properties:
--------------------
- ti,c64x+megamod-pic-mux: Array of 12 cells correspnding to the 12 core
priority interrupts. The first cell corresponds to
core priority 4 and the last cell corresponds to
core priority 15. The value of each cell is the
megamodule interrupt source which is MUXed to
the core interrupt corresponding to the cell
position. Allowed values are 4 - 127. Mapping for
interrupts 0 - 3 (combined interrupt sources) are
ignored.
Interrupt Specifier Definition
------------------------------
Single cell specifying the megamodule interrupt source (4-127). Note that
interrupts mapped directly to the core with "ti,c64x+megamod-pic-mux" will
use the core interrupt controller as their parent and the specifier will
be the core priority level, not the megamodule interrupt number.
Examples
--------
megamod_pic: interrupt-controller@1800000 {
compatible = "ti,c64x+megamod-pic";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0x1800000 0x1000>;
interrupt-parent = <&core_pic>;
interrupts = < 12 13 14 15 >;
};
This is a minimal example where all individual interrupts go through a
combiner. Combiner-0 is mapped to core interrupt 12, combiner-1 is mapped
to interrupt 13, etc.
megamod_pic: interrupt-controller@1800000 {
compatible = "ti,c64x+megamod-pic";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0x1800000 0x1000>;
interrupt-parent = <&core_pic>;
interrupts = < 12 13 14 15 >;
ti,c64x+megamod-pic-mux = < 0 0 0 0
32 0 0 0
0 0 0 0 >;
};
This the same as the first example except that megamodule interrupt 32 is
mapped directly to core priority interrupt 8. The node using this interrupt
must set the core controller as its interrupt parent and use 8 in the
interrupt specifier value.

CSR SiRFSoC Reset Controller
======================================
Please also refer to reset.txt in this directory for common reset
controller binding usage.
Required properties:
- compatible: Should be "sirf,prima2-rstc" or "sirf,marco-rstc"
- reg: should be register base and length as documented in the
datasheet

};
Specifying reset lines connected to IP modules
==============================================
The reset controller(rstc) manages various reset sources. This module provides
reset signals for most blocks in system. Those device nodes should specify the
reset line on the rstc in their resets property, containing a phandle to the
rstc device node and a RESET_INDEX specifying which module to reset, as described
in reset.txt.
For SiRFSoC, RESET_INDEX is just reset_bit defined in SW_RST0 and SW_RST1 registers.
For modules whose rest_bit is in SW_RST0, its RESET_INDEX is 0~31. For modules whose
rest_bit is in SW_RST1, its RESET_INDEX is 32~63.
example:
vpp@90020000 {
compatible = "sirf,prima2-vpp";
reg = <0x90020000 0x10000>;
interrupts = <31>;
clocks = <&clks 35>;

Timer64
-------
The timer64 node describes C6X event timers.
Required properties:
- compatible: must be "ti,c64x+timer64"
- reg: base address and size of register region
- interrupts: interrupt id
Optional properties:
- ti,dscr-dev-enable: Device ID used to enable timer IP through DSCR interface.
- ti,core-mask: on multi-core SoCs, bitmask of cores allowed to use this timer.
Example:
timer0: timer@25e0000 {
compatible = "ti,c64x+timer64";
ti,core-mask = < 0x01 >;
reg = <0x25e0000 0x40>;
interrupt-parent = <&megamod_pic>;
interrupts = < 16 >;
};

config C6X_BIG_KERNEL
bool "Build a big kernel"
help
The C6X function call instruction has a limited range of +/- 2MiB.
This is sufficient for most kernels, but some kernel configurations
with lots of compiled-in functionality may require a larger range
for function calls. Use this option to have the compiler generate
function calls with 32-bit range. This will make the kernel both
larger and slower.
If unsure, say N.
# Use the generic interrupt handling code in kernel/irq/
config CMDLINE_BOOL
bool "Default bootloader kernel arguments"
config CMDLINE
string "Kernel command line"
depends on CMDLINE_BOOL
default "console=ttyS0,57600"
help
On some architectures there is currently no way for the boot loader
to pass arguments to the kernel. For these architectures, you should
supply some command-line options at build time by entering them
here.
config CMDLINE_FORCE
bool "Force default kernel command string"
depends on CMDLINE_BOOL
default n
help
Set this to have arguments from the default kernel command string
override those passed by the boot loader.
config CPU_BIG_ENDIAN
bool "Build big-endian kernel"
default n
help
Say Y if you plan on running a kernel in big-endian mode.
Note that your board must be properly built and your board
port must properly enable any big-endian related features
of your chipset/board/processor.
config FORCE_MAX_ZONEORDER
int "Maximum zone order"
default "13"
help
The kernel memory allocator divides physically contiguous memory
blocks into "zones", where each zone is a power of two number of
pages. This option selects the largest power of two that the kernel
keeps in the memory allocator. If you need to allocate very large
blocks of physically contiguous memory, then you may need to
increase this value.
This config option is actually maximum order plus one. For example,
a value of 11 means that the largest free memory block is 2^10 pages.

help
Usually the pointer transfer from user space is checked to see if its
address is in the kernel space.
Say N here to disable that check to improve the performance.
