rcar-gen3: initial commit for the rcar-gen3 boards
Reference code: ============== rar_gen3: IPL and Secure Monitor Rev1.0.22 https://github.com/renesas-rcar/arm-trusted-firmware [rcar_gen3] Author: Takuya Sakata <takuya.sakata.wz@bp.renesas.com> Date: Thu Aug 30 21:26:41 2018 +0900 Update IPL and Secure Monitor Rev1.0.22 General Information: =================== This port has been tested on the Salvator-X Soc_id r8a7795 revision ES1.1 (uses an SPD). Build Tested: ------------- ATFW_OPT="LSI=H3 RCAR_DRAM_SPLIT=1 RCAR_LOSSY_ENABLE=1" MBEDTLS_DIR=$mbedtls $ make clean bl2 bl31 rcar PLAT=rcar ${ATFW_OPT} SPD=opteed Other dependencies: ------------------ * mbed_tls: git@github.com:ARMmbed/mbedtls.git [devel] Merge: 68dbc94 f34a4c1 Author: Simon Butcher <simon.butcher@arm.com> Date: Thu Aug 30 00:57:28 2018 +0100 * optee_os: https://github.com/BayLibre/optee_os Until it gets merged into OP-TEE, the port requires Renesas' Trusted Environment with a modification to support power management.

Author: Fabio Estevam <festevam@gmail.com> Date: Tue Sep 4 10:23:12 2018 -0300 *linux: The port has beent tested using mainline kernel. 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.
