Adding support for the new Arm corstone700 platform family.
The current supported corstone700 machine is corstone700-fvp.
The changes are as follows:
- Making some adjustments to the mmio timer and to the cortex-a5
designstart platform to share as much as possible between this
platforms.
- Disabling the use of the mmio_timer driver and enabling 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.
- adding bootx command to start XiP images

Introduction
This repository contains Arm layers for OpenEmbedded
meta-arm: This layer provides support for general recipes for the Arm architecture. Anything that's not needed explicitly for BSPs, the IOTA distribution, or destined to be upstreamed belongs here.
meta-arm-bsp: This layer provides support for Arm reference platforms
meta-arm-iota: This layer provides support for Arm's IOTA Linux Distribution
meta-arm-toolchain: This layer provides support for Arm's GNU-A toolset releases
meta-arm-autonomy: This layer provides a reference stack for autonomous systems.
Contributing
Currently, we only accept patches from the meta-arm mailing list. For general information on how to submit a patch, please read https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
E-mail meta-arm@lists.yoctoproject.org with patches created using this process. You can configure git-send-email to automatically use this address for the meta-arm repository with the following git command:
$ git config --local --add sendemail.to meta-arm@lists.yoctoproject.org
Commits and patches added should follow the OpenEmbedded patch guidelines:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
The component being changed in the shortlog should be prefixed with the layer name (without the meta- prefix), for example:
arm-bsp/trusted-firmware-a: decrease frobbing level
arm-toolchain/gcc: enable foobar v2
Reporting bugs
E-mail meta-arm@lists.yoctoproject.org with the error encountered and the steps to reproduce the issue.
