Migrate ARM platforms to use the new GICv3 API

2019-09-26T03:06:49Z

This patch invokes the new function gicv3_rdistif_probe() in the ARM platform specific gicv3 driver. Since this API modifies the shared GIC related data structure, it must be invoked coherently by using the platform specific pwr_domain_on_finish_late hook.

Refactor ARMv8.3 Pointer Authentication support code

2019-09-13T13:11:59Z

This patch provides the following features and makes modifications listed below: - Individual APIAKey key generation for each CPU. - New key generation on every BL31 warm boot and TSP CPU On event. - Per-CPU storage of APIAKey added in percpu_data[] of cpu_data structure. - `plat_init_apiakey()` function replaced with `plat_init_apkey()` which returns 128-bit value and uses Generic timer physical counter value to increase the randomness of the generated key. The new function can be used for generation of all ARMv8.3-PAuth keys - ARMv8.3-PAuth specific code placed in `lib\extensions\pauth`. - New `pauth_init_enable_el1()` and `pauth_init_enable_el3()` functions generate, program and enable APIAKey_EL1 for EL1 and EL3 respectively; pauth_disable_el1()` and `pauth_disable_el3()` functions disable PAuth for EL1 and EL3 respectively; `pauth_load_bl31_apiakey()` loads saved per-CPU APIAKey_EL1 from cpu-data structure. - Combined `save_gp_pauth_registers()` function replaces calls to `save_gp_registers()` and `pauth_context_save()`; `restore_gp_pauth_registers()` replaces `pauth_context_restore()` and `restore_gp_registers()` calls. - `restore_gp_registers_eret()` function removed with corresponding code placed in `el3_exit()`. - Fixed the issue when `pauth_t pauth_ctx` structure allocated space for 12 uint64_t PAuth registers instead of 10 by removal of macro CTX_PACGAKEY_END from `include/lib/el3_runtime/aarch64/context.h` and assigning its value to CTX_PAUTH_REGS_END. - Use of MODE_SP_ELX and MODE_SP_EL0 macro definitions in `msr spsel` instruction instead of hard-coded values. - Changes in documentation related to ARMv8.3-PAuth and ARMv8.5-BTI.

AArch64: Align crash reporting output

Switch AARCH32/AARCH64 to aarch64

2019-08-01T20:45:03Z

NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__. All common C compilers pre-define the same macros to signal which architecture the code is being compiled for: __arm__ for AArch32 (or earlier versions) and __aarch64__ for AArch64. There's no need for TF-A to define its own custom macros for this. In order to unify code with the export headers (which use __aarch64__ to avoid another dependency), let's deprecate the AARCH32 and AARCH64 macros and switch the code base over to the pre-defined standard macro. (Since it is somewhat unintuitive that __arm__ only means AArch32, let's standardize on only using __aarch64__.) Change-Id: Ic77de4b052297d77f38fc95f95f65a8ee70cf200 Signed-off-by: Julius Werner

Replace ASSEMBLY with compiler-builtin ASSEMBLER

2019-08-01T20:14:12Z

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__. All common C compilers predefine a macro called __ASSEMBLER__ when preprocessing a .S file. There is no reason for TF-A to define it's own __ASSEMBLY__ macro for this purpose instead. To unify code with the export headers (which use __ASSEMBLER__ to avoid one extra dependency), let's deprecate __ASSEMBLY__ and switch the code base over to the predefined standard.

arm: Shorten the Firmware Update (FWU) process

2019-07-23T09:41:41Z

The watchdog is configured with a default value of 256 seconds in order to implement the Trusted Board Boot Requirements. For the FVP and Juno platforms, the FWU process relies on a watchdog reset. In order to automate the test of FWU, the length of this process needs to be as short as possible. Instead of waiting for those 4 minutes to have a reset by the watchdog, tell it to reset immediately. There are no side effects as the value of the watchdog's load register resets to 0xFFFFFFFF. Tested on Juno. Change-Id: Ib1aea80ceddc18ff1e0813a5b98dd141ba8a3ff2 Signed-off-by: Ambroise Vincent

n1sdp: add code for DDR ECC enablement and BL33 copy to DDR

2019-06-26T13:07:51Z

N1SDP platform supports RDIMMs with ECC capability. To use the ECC capability, the entire DDR memory space has to be zeroed out before enabling the ECC bits in DMC620. Zeroing out several gigabytes of memory from SCP is quite time consuming so functions are added that zeros out the DDR memory from application processor which is much faster compared to SCP. BL33 binary cannot be copied to DDR memory before enabling ECC so this is also done by TF-A from IOFPGA-DDR3 memory to main DDR4 memory after ECC is enabled. Original PLAT_PHY_ADDR_SPACE_SIZE was limited to 36-bits with which the entire DDR space cannot be accessed as DRAM2 starts in base 0x8080000000. So these macros are redefined for all ARM platforms.

Add option for defining platform DRAM2 base

2019-05-15T10:42:39Z

The default DRAM2 base address for Arm platforms is 0x880000000. However, on some platforms the firmware may want to move the start address to a different value. To support this introduce PLAT_ARM_DRAM2_BASE that defaults to 0x880000000; but can be overridden by a platform (e.g. in platform_def.h).
