-# TC0 Platform Support in meta-arm-bsp
-
-## Overview
-The Total Compute platform provides an envelope for all of Arm's latest IP and
-software solutions, optimised to work together. Further information can be
-found on the Total Compute community page:
-https://community.arm.com/developer/tools-software/oss-platforms/w/docs/606/total-compute
-
-The user guide for TC0 platform with detailed instructions for
-syncing and building the source code and running on TC0 Fixed Virtual Platform
-for poky and android distributions is available at:
-https://git.linaro.org/landing-teams/working/arm/arm-reference-platforms.git/tree/docs/tc0/user-guide.rst
-
-## Building
-In the local.conf file, MACHINE should be set as follows:
-MACHINE = "tc0"
-
-To build the required binaries for tc0, run the commmand:
-```bash$ bitbake tc-artifacts-image```
-
-Trusted-firmware-a is the final component to be built with the rest of the
-components dependent of it, therefore building tc-artifacts-image which depends
-on trusted-firmware-a will build all the required binaries.
-
-## Running
-To run the produced binaries in a TC0 Fixed Virtual Platform please get
-the run scripts at:
-https://git.linaro.org/landing-teams/working/arm/model-scripts.git/
-
-and follow the instructions in the user-guide.rst available in:
-https://git.linaro.org/landing-teams/working/arm/arm-reference-platforms.git/tree/docs/tc0/user-guide.rst

-Subject: [PATCH 4/4] tc0: support platform feature set options in firmware.mk
-
-Support existing platform feature set options that is in cmake to
-firmware.mk. Two feature set for TC0 are
-0. Standard
-1. MPMM/Power/Performance (Experimental)
-
-Build option to select the feature set is using:
-make PRODUCT=tc0 MODE=<debug,release> SCP_PLATFORM_FEATURE_SET=<0,1>
-
-The default value is set to 0 (Standard).
-Refer product/tc0/doc/features.md for more details.

+
+Openamp is required to communicate between secure partitions(running on
+Cortex-A) and trusted-firmware-m(running on Cortex-M).
+These changes are to fetch libmetal and openamp from github repo's
+and build it.

+Subject: [PATCH 13/19] Add stub capsule update service components
+
+To facilitate development of a capsule update service provider,
+stub components are added to provide a starting point for an
+implementation. The capsule update service provider is integrated
+into the se-proxy/common deployment.

+Subject: [PATCH 19/19] plat: corstone1000: change default smm values
+
+Smm gateway uses SE proxy to route the calls for any NV
+storage so set the NV_STORE_SN.
+Change the storage index uid because TF-M in the secure
+enclave reserves the default value (0x1) to some internal
+operation.
+Increase the maximum number of uefi variables to cope with all
+the needs for testing and certification

+Subject: [PATCH] newlib: memcpy: remove optimized version
+
+When creating messages packed to send over openamp we may need
+to do some copy in unaligned address, because of that we may
+not always use the assembler optimized version, which will
+trough a data-abort on aligned address exception.
+
+So, we may just use the version in string.h (the same used in
+optee-os) that will take care to check and use different
+optimization based on given source or destination address's.
