This patch removes the need for a shared buffer between the EL3 and S-EL1 levels. We now use the CPU registers, x0-x7, while passing data between the two levels. Since TLK is a 32-bit Trusted OS, tlkd has to unpack the arguments in the x0-x7 registers. TLK in turn gets these values via r0-r7. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch adds support to open/close secure sessions with Trusted Apps and later send commands/events. Modify TLK_NUM_FID to indicate the total number of FIDs available to the NS world. Change-Id: I3f1153dfa5510bd44fc25f1fee85cae475b1abf1 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch allows servicing of the non-secure world IRQs when the CPU is in the secure world. Once the interrupt is handled, the non-secure world issues the Resume FID to allow the secure payload complete the preempted standard FID.

This patch adds functionality to translate virtual addresses from secure or non-secure worlds. This functionality helps Trusted Apps to share virtual addresses directly and allows the NS world to pass virtual addresses to TLK directly.

This patch registers NS memory buffer with the secure payload using two different functions IDs - REGISTER_LOGBUF, REGISTER_REQBUF. a. The SP uses the log-buffer to store its activity logs, in a pre-decided format. This helps in debugging secure payload's issues. b. The SP uses the req-buffer to get the parameters required by sessions with Trusted Applications.

TLK Dispatcher (tlkd) is based on the tspd and is the glue required to run TLK as a Secure Payload with the Trusted Firmware. Change-Id: I69e573d26d52342eb049feef773dd7d2a506f4ab Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch adds a tool that generates all the necessary elements to establish the chain of trust (CoT) between the images. The tool reads the binary images and signing keys and outputs the corresponding certificates that will be used by the target at run time to verify the authenticity of the images. Note: the platform port must provide the file platform_oid.h. This file will define the OIDs of the x509 extensions that will be added to the certificates in order to establish the CoT.

This patch adds the initial port of the ARM Trusted Firmware on the Juno development platform. This port does not support a BL3-2 image or any PSCI APIs apart from PSCI_VERSION and PSCI_CPU_ON. It enables workarounds for selected Cortex-A57 (#806969 & #813420) errata and implements the workaround for a Juno platform errata (Defect id 831273).

This patch adds CPU core and cluster power down sequences to the CPU specific operations framework introduced in a earlier patch. Cortex-A53, Cortex-A57 and generic AEM sequences have been added. The latter is suitable for the Foundation and Base AEM FVPs. A pointer to each CPU's operations structure is saved in the per-cpu data so that it can be easily accessed during power down seqeunces. An optional platform API has been introduced to allow a platform to disable the Accelerator Coherency Port (ACP) during a cluster power down sequence. The weak definition of this function (plat_disable_acp()) does not take any action. It should be overriden with a strong definition if the ACP is present on a platform.

This patch introduces a framework which will allow CPUs to perform implementation defined actions after a CPU reset, during a CPU or cluster power down, and when a crash occurs. CPU specific reset handlers have been implemented in this patch. Other handlers will be implemented in subsequent patches. Also moved cpu_helpers.S to the new directory lib/cpus/aarch64/.

Move the remaining IO storage source file (io_storage.c) from the lib to the drivers directory. This requires that platform ports explicitly add this file to the list of source files. Also move the IO header files to a new sub-directory, include/io. Change-Id: I862b1252a796b3bcac0d93e50b11e7fb2ded93d6

Update code base to remove variables from the .data section, mainly by using const static data where possible and adding the const specifier as required. Most changes are to the IO subsystem, including the framework APIs. The FVP power management code is also affected. Delay initialization of the global static variable, next_image_type in bl31_main.c, until it is realy needed. Doing this moves the variable from the .data to the .bss section. Also review the IO interface for inconsistencies, using uintptr_t where possible instead of void *. Remove the io_handle and io_dev_handle typedefs, which were unnecessary, replacing instances with uintptr_t. Fixes ARM-software/tf-issues#107. Change-Id: I085a62197c82410b566e4698e5590063563ed304

Reduce the number of header files included from other header files as much as possible without splitting the files. Use forward declarations where possible. This allows removal of some unnecessary "#ifndef __ASSEMBLY__" statements. Also, review the .c and .S files for which header files really need including and reorder the #include statements alphabetically. Fixes ARM-software/tf-issues#31 Change-Id: Iec92fb976334c77453e010b60bcf56f3be72bd3e

Move almost all system include files to a logical sub-directory under ./include. The only remaining system include directories not under ./include are specific to the platform. Move the corresponding source files to match the include directory structure. Also remove pm.h as it is no longer used. Change-Id: Ie5ea6368ec5fad459f3e8a802ad129135527f0b3

The modified implementation uses the IO abstraction rather than making direct semi-hosting calls. The semi-hosting driver is now registered for the FVP platform during initialisation of each boot stage where it is used. Additionally, the FVP platform includes a straightforward implementation of 'plat_get_image_source' which provides a generic means for the 'load_image' function to determine how to access the image data.

Ctags seem to have a problem with generating tags for assembler symbols when a comment immediately follows an assembly label. This patch inserts a single space character between the label definition and the following comments to help ctags. The patch is generated by the command: git ls-files -- \*.S | xargs sed -i 's/^\([^:]\+\):;/\1: ;/1' Change-Id: If7a3c9d0f51207ea033cc8b8e1b34acaa0926475
