ARM: stm32: Fix SYSRAM size on STM32MP13xx

2025-06-11T07:42:55Z

The STM32MP13xx has only 128 kiB of SYSRAM starting at address 0x2ffe0000 . The STM32MP15xx has 256 kiB of SYSRAM starting at address 0x2ffc0000 . Make sure both SoCs configure ARMV7_SECURE_BASE correctly . Define the SYSRAM base in stm32.h to be consistent with the STM32MP15xx macro. Signed-off-by: Marek Vasut Reviewed-by: Patrice Chotard

ARM: psci: move GIC address override to Kconfig

2023-10-11T17:22:32Z

As the code to switch an ARM core from secure to the non-secure state needs to know the base address of the Generic Interrupt Controller (GIC), we read an Arm Cortex defined system register that is supposed to hold that base address. However there are SoCs out there that get this wrong, and this CBAR register either reads as 0 or points to the wrong address. To accommodate those systems, so far we use a macro defined in some platform specific header files, for affected boards. To simplify future extensions, replace that macro with a Kconfig variable that holds this override address, and define a default value for SoCs that need it.

ARM: armv7: add non-SPL enable for Cortex SMPEN

2023-05-13T02:01:30Z

Commit 2564fce7eea3 ("sunxi: move Cortex SMPEN setting into start.S") added SPL_ARMV7_SET_CORTEX_SMPEN to enable setting SMP bit. For platforms not using SPL boot, add the corresponding non-SPL config, so that CONFIG_IS_ENABLED(ARMV7_SET_CORTEX_SMPEN) works as expected. Signed-off-by: Ralph Siemsen Reviewed-by: Marek Vasut

sunxi: move Cortex SMPEN setting into start.S

2022-02-04T00:09:36Z

According to their TRMs, Cortex ARMv7 CPUs with SMP support require the ACTLR.SMPEN bit to be set as early as possible, before any cache or TLB maintenance operations are done. As we do those things still in start.S, we need to move the SMPEN bit setting there, too. This introduces a new ARMv7 wide symbol and code to set bit 6 in ACTLR very early in start.S, and moves sunxi boards over to use that instead of the custom code we had in our board.c file (where it was called technically too late). In practice we got away with this so far, because at this point all the other cores were still in reset, so any broadcasting would have been ignored anyway. But it is architecturally cleaner to do it early, and we move a core specific piece of code out of board.c. This also gets rid of the ARM_CORTEX_CPU_IS_UP kludge I introduced a few years back, and moves the respective logic into the new Kconfig entry. Signed-off-by: Andre Przywara

ARM: add Kconfig option for PSCI 0.1

2020-08-05T12:18:34Z

We still have some platforms that only implements functionalities in PSCI 0.1 (e.g. Allwinner ARMv7 SoCs). Add a Kconfig option for exporting only PSCI 0.1. The code to export PSCI 0.1 is still available and gets activated by this patch. In addition, default ARCH_SUNXI U-Boot PSCI implementation to export PSCI 0.1, to fix poweroff/reboot regression on Allwinner multi-core ARMv7 SoCs. Signed-off-by: Icenowy Zheng
