Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca339 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Sun Sep 16 11:52:37 2018 -0700 Linux 4.19-rc4 Overview --------- BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered at this exception level (the Renesas' ATF reference tree [1] resets into EL1 before entering BL2 - see its bl2.ld.S) BL2 initializes DDR (and i2c to talk to the PMIC on some platforms) before determining the boot reason (cold or warm). During suspend all CPUs are switched off and the DDR is put in backup mode (some kind of self-refresh mode). This means that BL2 is always entered in a cold boot scenario. Once BL2 boots, it determines the boot reason, writes it to shared memory (BOOT_KIND_BASE) together with the BL31 parameters (PARAMS_BASE) and jumps to BL31. To all effects, BL31 is as if it is being entered in reset mode since it still needs to initialize the rest of the cores; this is the reason behind using direct shared memory access to BOOT_KIND_BASE and PARAMS_BASE instead of using registers to get to those locations (see el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use case). Depending on the boot reason BL31 initializes the rest of the cores: in case of suspend, it uses a MBOX memory region to recover the program counters.

- Fix build issue - Add initial memory parameters descriptors for BL2 - Migrate to image load V2 Basic build and run test passed on MacchiatoBin board. Need to fix the service CPU (CM3) image load procesure and test OPTEE functionality, which probably will require additional work. Signed-off-by: Konstantin Porotchkin <kostap@marvell.com>

This patch introduce TF-A support for NXP's ls1043a platform. more details information of ls1043a chip and ls1043ardb board can be found at docs/plat/ls1043a.rst. Boot sequence on ls1043a is: bootrom loads bl1 firstly, then bl1 loads bl2, bl2 will load bl31, bl32 and bl33, bl31 will boot bl32(tee os) and bl33(u-boot or uefi), bl33 boot Linux kernel. Now TF-A on ls1043ardb platform has the following features in this patch: * Support boot from Nor flash. * TF-A can boot bl33 which runs in el2 of non-secure world. * TF-A boot OPTee OS. * Support PSCI Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com> Signed-off-by: Chenyin.Ha <Chenyin.Ha@nxp.com> Signed-off-by: Chenhui Zhao <chenhui.zhao@nxp.com> Signed-off-by: jiaheng.fan <jiaheng.fan@nxp.com> Signed-off-by: Wen He <wen.he_1@nxp.com>

This patch adds changes in ARM platform code to use new version of image loading. Following are the major changes: -Refactor the signatures for bl31_early_platform_setup() and arm_bl31_early_platform_setup() function to use `void *` instead of `bl31_params_t *`. -Introduce `plat_arm_bl2_handle_scp_bl2()` to handle loading of SCP_BL2 image from BL2. -Remove usage of reserve_mem() function from `arm_bl1_early_platform_setup()` -Extract BL32 & BL33 entrypoint info, from the link list passed by BL2, in `arm_bl31_early_platform_setup()` -Provides weak definitions for following platform functions: plat_get_bl_image_load_info plat_get_next_bl_params plat_flush_next_bl_params bl2_plat_handle_post_image_load -Instantiates a descriptor array for ARM platforms describing image and entrypoint information for `SCP_BL2`, `BL31`, `BL32` and `BL33` images. All the above changes are conditionally compiled using the `LOAD_IMAGE_V2` flag. Change-Id: I5e88b9785a3df1a2b2bbbb37d85b8e353ca61049

* Move TSP platform porting functions to new file: include/bl32/tsp/platform_tsp.h. * Create new TSP_IRQ_SEC_PHY_TIMER definition for use by the generic TSP interrupt handling code, instead of depending on the FVP specific definition IRQ_SEC_PHY_TIMER. * Rename TSP platform porting functions from bl32_* to tsp_*, and definitions from BL32_* to TSP_*. * Update generic TSP code to use new platform porting function names and definitions. * Update FVP port accordingly and move all TSP source files to: plat/fvp/tsp/. * Update porting guide with above changes. Note: THIS CHANGE REQUIRES ALL PLATFORM PORTS OF THE TSP TO BE UPDATED Fixes ARM-software/tf-issues#167 Change-Id: Ic0ff8caf72aebb378d378193d2f017599fc6b78f

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
