arm: docs: Move Arm documentation to Documentation/arch/

Architecture-specific documentation is being moved into Documentation/arch/
as a way of cleaning up the top-level documentation directory and making
the docs hierarchy more closely match the source hierarchy.  Move
Documentation/arm into arch/ (along with the Chinese equvalent
translations).

-======================================================================
-Texas Instruments Keystone Navigator Queue Management SubSystem driver
-======================================================================
-
-Driver source code path
-  drivers/soc/ti/knav_qmss.c
-  drivers/soc/ti/knav_qmss_acc.c
-
-The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
-the main hardware sub system which forms the backbone of the Keystone
-multi-core Navigator. QMSS consist of queue managers, packed-data structure
-processors(PDSP), linking RAM, descriptor pools and infrastructure
-Packet DMA.
-The Queue Manager is a hardware module that is responsible for accelerating
-management of the packet queues. Packets are queued/de-queued by writing or
-reading descriptor address to a particular memory mapped location. The PDSPs
-perform QMSS related functions like accumulation, QoS, or event management.
-Linking RAM registers are used to link the descriptors which are stored in
-descriptor RAM. Descriptor RAM is configurable as internal or external memory.
-The QMSS driver manages the PDSP setups, linking RAM regions,
-queue pool management (allocation, push, pop and notify) and descriptor
-pool management.
-
-knav qmss driver provides a set of APIs to drivers to open/close qmss queues,
-allocate descriptor pools, map the descriptors, push/pop to queues etc. For
-details of the available APIs, please refers to include/linux/soc/ti/knav_qmss.h
-
-DT documentation is available at
-Documentation/devicetree/bindings/soc/ti/keystone-navigator-qmss.txt
-
-Accumulator QMSS queues using PDSP firmware
-============================================
-The QMSS PDSP firmware support accumulator channel that can monitor a single
-queue or multiple contiguous queues. drivers/soc/ti/knav_qmss_acc.c is the
-driver that interface with the accumulator PDSP. This configures
-accumulator channels defined in DTS (example in DT documentation) to monitor
-1 or 32 queues per channel. More description on the firmware is available in
-CPPI/QMSS Low Level Driver document (docs/CPPI_QMSS_LLD_SDS.pdf) at
-
-	git://git.ti.com/keystone-rtos/qmss-lld.git
-
-k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin firmware supports upto 48 accumulator
-channels. This firmware is available under ti-keystone folder of
-firmware.git at
-
-   git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
-
-To use copy the firmware image to lib/firmware folder of the initramfs or
-ubifs file system and provide a sym link to k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin
-in the file system and boot up the kernel. User would see
-
- "firmware file ks2_qmss_pdsp_acc48.bin downloaded for PDSP"
-
-in the boot up log if loading of firmware to PDSP is successful.
-
-Use of accumulated queues requires the firmware image to be present in the
-file system. The driver doesn't acc queues to the supported queue range if
-PDSP is not running in the SoC. The API call fails if there is a queue open
-request to an acc queue and PDSP is not running. So make sure to copy firmware
-to file system before using these queue types.

-==========================
-TI Keystone Linux Overview
-==========================
-
-Introduction
-------------
-Keystone range of SoCs are based on ARM Cortex-A15 MPCore Processors
-and c66x DSP cores. This document describes essential information required
-for users to run Linux on Keystone based EVMs from Texas Instruments.
-
-Following SoCs  & EVMs are currently supported:-
-
-K2HK SoC and EVM
-=================
-
-a.k.a Keystone 2 Hawking/Kepler SoC
-TCI6636K2H & TCI6636K2K: See documentation at
-
-	http://www.ti.com/product/tci6638k2k
-	http://www.ti.com/product/tci6638k2h
-
-EVM:
-  http://www.advantech.com/Support/TI-EVM/EVMK2HX_sd.aspx
-
-K2E SoC and EVM
-===============
-
-a.k.a Keystone 2 Edison SoC
-
-K2E  -  66AK2E05:
-
-See documentation at
-
-	http://www.ti.com/product/66AK2E05/technicaldocuments
-
-EVM:
-   https://www.einfochips.com/index.php/partnerships/texas-instruments/k2e-evm.html
-
-K2L SoC and EVM
-===============
-
-a.k.a Keystone 2 Lamarr SoC
-
-K2L  -  TCI6630K2L:
-
-See documentation at
-	http://www.ti.com/product/TCI6630K2L/technicaldocuments
-
-EVM:
-  https://www.einfochips.com/index.php/partnerships/texas-instruments/k2l-evm.html
-
-Configuration
--------------
-
-All of the K2 SoCs/EVMs share a common defconfig, keystone_defconfig and same
-image is used to boot on individual EVMs. The platform configuration is
-specified through DTS. Following are the DTS used:
-
-	K2HK EVM:
-		k2hk-evm.dts
-	K2E EVM:
-		k2e-evm.dts
-	K2L EVM:
-		k2l-evm.dts
-
-The device tree documentation for the keystone machines are located at
-
-        Documentation/devicetree/bindings/arm/keystone/keystone.txt
