global: Rename SPL_TPL_ to PHASE_

2024-10-11T17:44:48Z

Use PHASE_ as the symbol to select a particular XPL build. This means that SPL_TPL_ is no-longer set. Update the comment in bootstage to refer to this symbol, instead of SPL_ Signed-off-by: Simon Glass

rng: Add Exynos TRNG driver

2024-07-24T07:37:09Z

Add True Random Number Generator (TRNG) driver for Exynos chips. This implementation is heavily based on Linux kernel's counterpart [1]. It also follows upstream dt-bindings [2]. TRNG block is usually a part of SSS (Security Sub System) IP-core on Exynos chips. Because SSS access on Exynos850 is protected by TZPC (TrustZone Protection Control), it's not possible to read/write TRNG registers from U-Boot, as it's running in EL1 mode. Instead, the corresponding SMC calls should be used to make the secure software running in EL3 mode access it for us. Those SMC calls are handled by LDFW (Loadable Firmware), which has to be loaded first. For example, for E850-96 board it's done in its board_init(), so by the time RNG capabilities are needed the LDFW should be already loaded and TRNG should be functional.

driver: rng: Do not check ARM_SMCCC_TRNG_VERSION

2024-07-18T13:40:30Z

As described in the document SMC Calling Convention (ARM DEN 0028 1.5 F), section 7 "Arm Architecture Calls", the SMC call SMCCC_ARCH_FEATURES is not expected to support the function ID ARM_SMCCC_TRNG_VERSION. Trusted Firmware-A follows up the specification in its implementation. This commit removes the invocation to avoid the failure - which is a wrong calling in U-boot. The later code invokes ARM_SMCCC_TRNG_VERSION for retrieving the TRNG version, except it can read back the version number, it also can be used to detect whether the TRNG is supported or not.

rng: Introduce SPL_DM_RNG

2024-05-05T14:21:39Z

Add SPL variant of DM_RNG so that the DM_RNG can be disabled in SPL if necessary. This may be necessary due to e.g. size constraints of the SPL. Signed-off-by: Marek Vasut

rockchip: include asm/io.h directly in asm/arch-rockchip/hardware.h

2024-03-13T10:15:52Z

The different macros use writel which is defined in asm/io.h, so let's include the header so users of hardware.h do not need to include asm/io.h as well. While at it, remove asm/io.h includes wherever asm/arch-rockchip/hardware.h is included already. Cc: Quentin Schulz Reviewed-by: Kever Yang Signed-off-by: Quentin Schulz
