Corstone 700 is end-of-life, so remove it from meta-arm master.

It will remain in the stable branches for existing users, but new users
are encouraged to use Corstone 1000 instead.

-# Corstone-700
-
-## Overview
-
-Corstone-700 is a flexible compute architecture combining Cortex-A and Cortex-M
-processors and a secure enclave, aimed at building secure IoT SoCs.  There are
-machines for both Corstone-700 for Fixed Virtual Platform (`corstone700-fvp`)
-and Corstone-700 for MPS3 FPGA (`corstone700-mps3`).
-
-Further details are available in the [User Guide].
-
-## Building
-
-Corstone-700 is tested in 'tiny' configurations, such as `DISTRO="poky-tiny"`.
-
-## Running
-
-For detailed instructions as to how to run the image in a FVP model, or on the
-MPS3 board, see the [User Guide].

-Subject: [PATCH] tools/gen_module_code: atomically rewrite the generated files
-
-The gen_module rule in rules.mk is marked as .PHONY, so make will
-execute it whenever it is mentioned. This results in gen_module_code
-being executed 64 times for a Juno build.
-
-However in heavily parallel builds there's a good chance that
-gen_module_code is writing a file whilst the compiler is reading it
-because make also doesn't know what files are generated by
-gen_module_code.
-
-The correct fix is to adjust the Makefiles so that the dependencies are
-correct but this isn't trivial, so band-aid the problem by atomically
-writing the generated files.

-Subject: [PATCH 6/6] arm: enabling the arch_timer driver
-
-This patch disables the use of the mmio_timer driver
-and enables the arch_timer driver.
-
-The mmio_timer tries a direct access to the Armv8-A CNTFRQ generic timer
-frequency register through memory mapping. This can not be done because
-this register is only accessible through memory mapping under a secure
-mode only. u-boot runs in non secure Hypervisor mode. To read the counter
-frequency u-boot should use the mrc instruction to read the CNTFRQ system
-register.
-
-The arch_timer driver reads the CNTFRQ register using the mrc instruction.

-Subject: [PATCH 01/20] arm: support for a single ARMv7-A based platform.
-
-The reason for having a single ARMv7A based platform is to bypass
-collection of configs provided/concealed by ARCH_MULTIPLATFORM, for
-example XIP_KERNEL cannot be enabled with ARCH_MULTIPLATFORM.
-
-Having a separate config for single ARMv7-A platform will give the
-freedom to choose only those configs which are required for a given
-ARMv7-A based platform.

-Subject: [PATCH 04/20] add driver of mailbox handling unit controller version
- 2
-
-this driver design is based on MHUv1 driver.
-But there is change of logic while reading device tree
-entry because MHUv2.1 has sender and receiver channels
-separate.
-
-ARM has launched a next version of MHU i.e. MHUv2 with its latest
-subsystems. The main change is that the MHUv2 is now a distributed IP
-with different peripheral views (registers) for the sender and receiver.
-
-Another main difference is that MHUv1 duplex channels are now split into
-simplex/half duplex in MHUv2. MHUv2 has a configurable number of
-communication channels. There is a capability register (MSG_NO_CAP) to
-find out how many channels are available in a system.
-
-The register offsets have also changed for STAT, SET & CLEAR registers
-from 0x0, 0x8 & 0x10 in MHUv1 to 0x0, 0xC & 0x8 in MHUv2 respectively.
-
-0x0    0x4  0x8  0xC             0x1F
-------------------------....-----
-| STAT |    |    | SET |    |   |
-------------------------....-----
-      Transmit Channel
-
-0x0    0x4  0x8   0xC            0x1F
-------------------------....-----
-| STAT |    | CLR |    |    |   |
-------------------------....-----
-        Receive Channel
-
-The MHU controller can request the receiver to wake-up and once the
-request is removed, the receiver may go back to sleep, but the MHU
-itself does not actively puts a receiver to sleep.
-
-So, in order to wake-up the receiver when the sender wants to send data,
-the sender has to set ACCESS_REQUEST register first in order to wake-up
-receiver, state of which can be detected using ACCESS_READY register.
-ACCESS_REQUEST has an offset of 0xF88 & ACCESS_READY has an offset
-of 0xF8C and are accessible only on any sender channel.
-
-This patch adds necessary changes in a new file required to support the
-latest MHUv2 controller. This patch also need an update in DT binding for
-ARM MHUv2 as we need a second register base (tx base) which would be used
-as the send channel base.

-Subject: [PATCH 07/20] allow creation of multiple arm rpmsg channels
-
-This commit introduces support for accessing multiple channels
-through the arm rpmsg driver.
-To do this, information connecting rpmsg endpoints, mailbox channels
-and mailbox names are stored for each created endpoint.
-rpmsg endpoints and now to be created by referring to mailbox
-names defined in the device-tree.

-Subject: [PATCH 09/20] misc: arm: add corstone700 external system harness
- driver
-
-This commit adds a driver and device node for controlling the external
-system harness of arm corstone700.
-Currently, the only functionality is ioctl command: 0x0, which will
-deassert the CPU_WAIT pin of the external system harness attached to the
-driver.

-Subject: [PATCH 10/20] arm: containerize endpoint and mailbox information
-
-This commit adds the rpmsg_endpoint and mbox_client structs as members of the
-arm_channel struct. This allows for usage of the container_of macro, vastly
-simplifying lookup between endpoints and mailboxes.
-
-Furthermore, a memory leak from the allocation of mbox_client's is fixed.

-Subject: [PATCH 11/20] arm: couple mailbox channel ownership to rpmsg endpoint
- lifecycle
-
-Previously, mailbox channels would be assigned once a write occured to the
-endpoint. This presents an issue wherein if a mailbox is opened with a given
-destination channel, and then read from, instead of writing to it, the target
-mailbox channel would not bind to the mailbox client, and thus not forward its
-received message to the rpmsg endpoint.
-
-This commits moves the ownership of a mailbox channel to the lifecycle of an
-rpmsg endpoint, thus registerring the mailbox channel with the mailbox client
-once the rpmsg endpoint is opened in userspace.

-
-Typically, hardware reports number of channels it supports.
-Software should read the appropriate registers to determine the
-number of channels support and should make the allocations
-accordingly. This change is to achieve it by removing static allocation
-and making dynamic allocations.

-Subject: [PATCH 15/20] arm: Kconfig: disable ARM_VIRT extension if XIP_KERNEL
-
-XIP is intended to execute kernel inplace and typically from
-flash and is used mostly on low memory devices.
-
-.macro  store_primary_cpu_mode  reg1, reg2, reg3
-        mrs     \reg1, cpsr
-        and     \reg1, \reg1, #MODE_MASK
-        adr     \reg2, .L__boot_cpu_mode_offset
-        ldr     \reg3, [\reg2]
-        str     \reg1, [\reg2, \reg3]
-
-As text section is in flash memory and data section is in RAM.
-L__boot_cpu_mode_offset would evaluate to address based
-on virtual addresses provided by linker script. At this stage
-the MMU is OFF.
-
-The logic used based stored @L__boot_cpu_mode_offset on the offset
-between the  boot_cpu_mode in data section and the location of
-L__boot_cpu_mode_offset can't be used along with PC to fetch the value
-of boot_cpu_mode doesn't work.
-
-This change is to disable CONFIG_ARM_VIRT_EXT for XIP kernel

-
-Because the NOR flash is already mapped and read-accessible
-before the kernel starts, so we don't need a QSPI driver to

-MTD_CFI. Otherwise, the kernel will verify CFI compliancy

-Subject: [PATCH 20/20] usb: isp1760: add support for isp1763
-
-isp1763 have some differences from the isp1760, 8 bit address for
-registers and 16 bit for values, no bulk access to memory addresses,
-16 PTD's instead of 32.
-
-Following the regmap work done before add the registers, memory access
-and add the functions to support differences in setup sequences.
