SC_R_GIC_SMMU is a master resource, we can't set peripheral permission to this resource, otherwise the API will return below error on latest SCFW, because SCFW has added a resource type check. On old SCFW, the API does nothing to a master resource. So remove the resource from ns_access_allowed array.

2019-12-13imx: initialize register value before writting MU_SR registerAnson Huang
MU_SR register bit[30] is cold boot flag passed from SCU, w0 is random value and would clear the flag incorrectly, and cause system partition reboot fail if Linux is in suspend. So this patch initializes it to 0x80000000 which is exactly the same with first time board power up before writting to MU_SR register. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
2019-12-13imx: fix partition reboot fail when debug console is enabledAnson Huang
With partition reboot enabled, console_list variable which is located in data section is NOT reset, system will be busy looping in early console operation of flush_loop() if console_list is NOT 0 while HW console is NOT initialized, so we have to clear this variable to make partition reboot work.

2019-12-13gic: make sure ProcessorSleep bit clear successfullyAnson Huang
GICR_WAKER.ProcessorSleep can only be set to zero when: — GICR_WAKER.Sleep bit[0] == 0. — GICR_WAKER.Quiescent bit[31] == 0. On some platforms, when system reboot with GIC in sleep mode but with power ON, such as on NXP's i.MX8QM, Linux kernel enters suspend but could be requested to reboot, and GIC is in sleep mode and it is inside a power domain which is ON in this scenario, when CPU reset, the GIC driver trys to set CORE's redistributor interface to awake, with GICR_WAKER.Sleep bit[0] and GICR_WAKER.Quiescent bit[31] both set, the ProcessorSleep bit[1] will never be clear and cause system hang. This patch makes sure GICR_WAKER.Sleep bit[0] and GICR_WAKER.Quiescent bit[31] are both zeor before clearing ProcessorSleep bit[1]. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

2019-12-13imx8: postpone moving resources to non-secure partitionPeng Fan
With flash_uboot_cm4ddr in imx-mkimage, the m4 code will access ddr. However after m4 core moved to non-secure partition, the ddr memory is still in secure partition. Then m4 core will fault. So postpone moving resources including m4 core, until other resources, such as memory/pin moved to non-secure partition.

2019-12-13imx8qxp: move M4 to OS part at lastPeng Fan
With default configuration, M4 and A35 in one partition, M4 is loaded by ROM. "err = sc_rm_move_all(ipc_handle, secure_part, os_part, true, true);" M4 core will first be moved to non-secure OS part, then the resource used by M4 will be moved to non-secure OS part later. But before the resource be moved to non-secure OS part, M4 core is still running, so a non-secure M4 core access a secure resource will trigger error in M4 side. First mark M4 core as non-movable, after all other resoures moved to OS part, move M4 to OS part. No need to check whether M4 is created a new partition by SCFW, if a partition already created, the call to mark M4 as non-removable will fail, because it M4 is in its own partition.

2019-10-21doc: Move platform list to the Platform Ports index pagePaul Beesley
The list of upstream platforms on the index page is growing quite long, especially with all the FVP variants being listed individually. This patch leverages the "Platform Ports" chapter in the docs table of contents to condense this information. Almost all platform ports now have documentation, so the table of contents serves as the list of upstream platforms by itself. For those upstream platforms that do not have corresponding documentation, the top-level "Platform Ports" page mentions them individually. It also mentions each Arm FVP, just as the index page did before. Note that there is an in-progress patch that creates new platform port documentation for the Arm Juno and Arm FVP platforms, so this list of "other platforms" will soon be reduced further as those platforms become part of the table of contents as well.

It contains quite a lot of content these days, including: - The project purpose and general intro - A list of functionality - A list of planned functionality - A list of supported platforms - "Getting started" links to other documents - Contact information for raising issues This patch creates an "About" chapter in the table of contents and moves some content there. In order, the above listed content: - Stayed where it is. This is the right place for it. - Moved to About->Features - Moved to About->Features (in subsection) - Stayed where it is. Moved in a later patch. - Was expanded in-place - Moved to About->Contact Change-Id: I254bb87560fd09140b9e485cf15246892aa45943 Signed-off-by: Paul Beesley <paul.beesley@arm.com>

2019-10-18xlat_table_v2: Fix enable WARMBOOT_ENABLE_DCACHE_EARLY configArtsem Artsemenka
The WARMBOOT_ENABLE_DCACHE_EARLY allows caches to be turned on early during the boot. But the xlat_change_mem_attributes_ctx() API did not do the required cache maintenance after the mmap tables are modified if WARMBOOT_ENABLE_DCACHE_EARLY is enabled. This meant that when the caches are turned off during power down, the tables in memory are accessed as part of cache maintenance for power down, and the tables are not correct at this point which results in a data abort. This patch removes the optimization within xlat_change_mem_attributes_ctx() when WARMBOOT_ENABLE_DCACHE_EARLY is enabled.

2019-10-09doc: Formatting fixes for readme.rstPaul Beesley
The readme.rst file in the project root is the front-page that is displayed on Github and if viewing the TF-A repository on git.trustedfirmware.org in the "about" view. It now contains a small amount of stub content, and directs readers to the ReadTheDocs documentation via trustedfirmware.org/docs/tf-a. The Github renderer is displaying the content fine but the cgit viewer displays some "backlink" errors because some content substitutions were left in place (terms surrounded by pipe symbols), e.g. |TF-A|. This patch removes those substitutions, that are not supported by cgit, and also updates one heading to clarify where to find the new docs.
