* plat/arm: Support direct Linux kernel boot in AArch32Manish Pandey2018-11-051-5/+6
| | | | | | | | | | | | This option allows the Trusted Firmware to directly jump to Linux kernel for aarch32 without the need of an intermediate loader such as U-Boot. Similar to AArch64 ARM_LINUX_KERNEL_AS_BL33 only available with RESET_TO_SP_MIN=1 as well as BL33 and DTB are preloaded in memory.

| * mvebu: cp110: introduce COMPHY porting layerGrzegorz Jaszczyk2018-10-181-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of COMPHY parameters depends on the hw connection between the SoC and the PHY, which can vary on different boards e.g. due to different wires length. Define the "porting layer" with some defaults parameters. It ease updating static values which needs to be updated due to board differences, which are now grouped in one place. Example porting layer for a8k-db is under: plat/marvell/a8k/a80x0/board/phy-porting-layer.h If for some boards parameters are not defined (missing phy-porting-layer.h), the default values are used (drivers/marvell/comphy/phy-default-porting-layer.h) and the following compilation warning is show: "Using default comphy params - you may need to suit them to your board". The common COMPHY driver code is extracted in order to be shared with future COMPHY driver for A3700 SoC platforms Signed-off-by: Grzegorz Jaszczyk <jaz@semihalf.com> Signed-off-by: Igal Liberman <igall@marvell.com> Signed-off-by: Konstantin Porotchkin <kostap@marvell.com>

* | rpi3: Add mem reserve region to DTB if presentAntonio Nino Diaz2018-10-241-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Mbed TLS drivers, in order to work, need a heap for internal usage. This heap, instead of being directly referenced by the drivers, now it is being accessed indirectly through a pointer. Also, the heap, instead of being part of the drivers, now it is being received through the plat_get_mbedtls_heap() function. This function requests a heap from the current BL image which utilises the Mbed TLS drivers. Those changes create the opportunity for the Mbed TLS heap to be shared among different images, thus saving memory. A default heap implementation is provided but it can be overridden by a platform specific, optimised implemenetation.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug in the context management code that causes it to ignore the HANDLE_EA_EL3_FIRST compile-time option and instead always configure SCR_EL3 to force all external aborts to trap into EL3. The code used #ifdef to read compile-time option declared with add_define in the Makefile... however, those options are always defined, they're just defined to either 0 or 1, so #if is the correct syntax to check for them. Also update the documentation to match. This bug has existed since the Nov 2017 commit 76454abf4 (AArch64: Introduce External Abort handling), which changed the HANDLE_EA_EL3_FIRST option to use add_define.
