When a device tree blob is present at a known address, instead of, for example, relying on the user modifying the Linux command line to warn about the memory reserved for the Trusted Firmware, pass it on the DTB. The current code deletes the memory reserved for the default bootstrap of the Raspberry Pi and adds the region used by the Trusted Firmware. This system replaces the previous one consisting on adding ``memmap=16M$256M`` to the Linux command line. It's also meant to be used by U-Boot and any other bootloader that understands DTB files.

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.

2018-10-16	3ff4aaa Browse files » AArch64: Enable lower ELs to use pointer authentication ... Pointer authentication is an Armv8.3 feature that introduces instructions that can be used to authenticate and verify pointers. Pointer authentication instructions are allowed to be accessed from all ELs but only when EL3 explicitly allows for it; otherwise, their usage will trap to EL3. Since EL3 doesn't have trap handling in place, this patch unconditionally disables all related traps to EL3 to avoid potential misconfiguration leading to an unhandled EL3 exception.

2018-10-03	37c4341 Browse files » marvell: Move BLE from external repo to the platform folder ... The BLE is the pre-TF-A boot stage required by Marvell Armada BootROM for bringing up DRAM and allow the boot image copy to it. Since this is not a standard boot level and only uses the TF-A as a build environment, it was introduced out of source tree. However it turns out that such remote location introduces additional complexity to the upstream TF-A build process. In order to simplify the build environment the BLE source folder is relocated from the external repository to A8K platform directory. The build documentation is updated accordingly.

	c0740e4 Browse files » plat/arm: Remove option ARM_BOARD_OPTIMISE_MEM ... This option makes it hard to optimize the memory definitions of all Arm platforms because any change in the common defines must work in all of them. The best thing to do is to remove it and move the definition to each platform's header. FVP, SGI and SGM were using the definitions in board_arm_def.h. The definitions have been copied to each platform's platform_def.h. Juno was already using the ones in platform_def.h, so there have been no changes.
