2020-08-05ARM: add Kconfig option for PSCI 0.1Icenowy Zheng
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 <icenowy@aosc.io>
2020-07-29arm: add support for SoC s5p4418 (cpu) / nanopi2 boardStefan Bosch
Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - SPL not supported yet --> no spl-dir in arch/arm/cpu/armv7/s5p4418/. Appropriate line in Makefile removed. - cpu.c: '#include <cpu_func.h>' added. - arch/arm/cpu/armv7/s5p4418/u-boot.lds removed, is not required anylonger. - "obj-$(CONFIG_ARCH_NEXELL) += s5p-common/" added to arch/arm/cpu/armv7/Makefile since s5p-common/pwm.c is used instead of drivers/pwm/pwm-nexell.c. - s5p4418.dtsi: '#include "../../../include/generated/autoconf.h"' removed, is not necessary, error at out-of-tree building. '#ifdef CONFIG_CPU_NXP4330'-blocks (2x) removed. Some minor changes regarding mmc. 'u-boot,dm-pre-reloc' added to dp0 because of added DM_VIDEO support. - board/s5p4418/ renamed to board/friendlyarm/ - All s5p4418-boards except nanopi2 removed because there is no possibility to test the other boards. - Kconfig: Changes to have a structure like mach-bcm283x (RaspberryPi), e.g. "config ..." entries moved from/to other Kconfig. - "CONFIG_" removed from several s5p4418/nanopi2 specific defines because the appropriate values do not need to be configurable. - nanopi2/board.c: All getenv(), getenv_ulong(), setenv() and saveenv() renamed to env_get(), env_get_ulong(), env_set() and env_save(), respectively. MACH_TYPE_S5P4418 is not defined anymore, therefore appropriate code removed (not necessary for DT-kernels). - nanopi2/onewire.c: All crc8() renamed to crc8_ow() because crc8() is already defined in lib/crc8.c (with different parameters). - dts: "nexell,s5pxx18-i2c" used instead of "i2c-gpio", i2c0 and i2c1 added. gmac-, ehci- and dwc2otg-entries removed because the appropriate functionality is not supported yet. New mmc-property "mmcboost" added. s5p4418-pinctrl.dtsi: gmac-entries removed, mmc- and i2c-entries added. - '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where possible (and similar).

2020-07-29pwm: add driver for nexellStefan Bosch
Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01: - Since drivers/pwm/pwm-nexell.c is an adapted version of s5p-common/pwm.c an appropriately changed version of s5p-common/pwm.c is used instead. Therefore arch/arm/mach-s5pc1xx/include/mach/pwm.h copied to arch/arm/mach-nexell/include/mach and s5p-common/Makefile changed appropriately. - '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where possible (and similar).

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them.

2018-12-02efi_loader: PSCI reset and shutdownHeinrich Schuchardt
When an operating system started via bootefi tries to reset or power off this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system the actual reset relies on PSCI. Depending on whether the PSCI firmware resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC or an SMC command has to be issued. The current implementation always uses SMC. This results in crashes on systems where the PSCI firmware is implemented in the hypervisor, e.g. qemu-arm64_defconfig. The logic to decide which call is needed based on the device tree is already implemented in the PSCI firmware driver. During the EFI runtime the device driver model is not available. But we can minimize code duplication by merging the EFI runtime reset and poweroff code with the PSCI firmware driver. As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff and reset_misc routines let's move them into the same code module.
