Add the compatible entry and corresponding chip data for Exynos7 compatible chips, which covers modern ARM64 based Exynos chips. They have some differences w.r.t. old ARM32 Exynos chips: - CLKSEL register offset is different - 64-bit IDMAC descriptor and 64-bit IDMAC registers are used (implemented in dw_mmc core driver) In terms of the driver implementation, the CIU clock is obtained via CCF framework (as opposed to ad-hoc clock driver implementation for ARM32 chips).

2024-05-28arm: exynos: Migrate E850-96 board to OF_UPSTREAMSam Protsenko1-0/+1
Use upstream device tree files and bindings. To do so: - imply (enable) OF_UPSTREAM option for E850-96 target - point DEFAULT_DEVICE_TREE in E850-96 config to upstream dts - remove now not needed local dts files, binding docs and headers - update MAINTAINERS and board/samsung/e850-96/MAINTAINERS correspondingly Upstream device tree files for Exynos850 SoC and E850-96 board are pretty much the same as local (removed) ones, so the conversion is rather straightforward and painless in this case. The appended dts file (arch/arm/dts/exynos850-e850-96-u-boot.dtsi) stays unchanged. The only remaining local dt-bindings doc for E850-96 board is exynos-pmu.yaml. It wasn't removed as it's quite different from Linux kernel version. Particularly U-Boot local version of exynos-pmu.yaml describes "samsung,uart-debug-1" property, which is not present in Linux kernel binding. Later it might be upstreamed to Linux kernel, and once it's done the U-Boot exynos-pmu.yaml binding can be removed. No functional change.

2024-05-13arm: Move sev() and wfe() definitions to common Arm header filePeter Hoyes1-19/+0
The sev() and wfe() asm macros are currently defined only for mach-exynos. As these are common Arm instructions, move them to the common asm/system.h header file, for both Armv7 and Armv8, so they can be used by other machines. wfe may theoretically trigger a context switch if an interrupt occurs so add a memory barrier to this call.

2024-01-24board: samsung: Add support for E850-96 boardSam Protsenko1-1/+18
Add support for WinLink E850-96 board [1]. It's based on Exynos850 SoC and follows 96boards specification, so it's compatible with 96boards mezzanine boards [2]. This patch enables next features: * Serial console * USI * PMU (muxing AP UART path) * Pinctrl * Clocks * Timer (ARMv8 architected) * Reset control It's quite a minimal enablement. Features like MMC, USB and Ethernet will be enabled later. The rationale for config values is as follows: * TEXT_BASE = 0xf8800000 That's where BL2 loads the U-Boot payload, so TEXT_BASE must be exactly this value. Overall the memory map is designed in a way to keep the bootloader in the upper 128 MiB area of RAM, which is 0xf8000000..0xffffffff. That includes bootloader's code, stack, data, heap, MMU tables, etc. All the memory below that 128 MiB chunk can be used for storing boot images (0x80000000..0xf8000000). * CUSTOM_SYS_INIT_SP_ADDR = 0xf8c00000 Just 4 MiB above the TEXT_BASE address, to leave enough space for U-Boot code and stack itself (grows downwards). * SYS_LOAD_ADDR = 0x80000000 The beginning of RAM. That's where Linux kernel image must be loaded. * SYS_MALLOC_LEN = 0x81f000 8 MiB for malloc() + ENV_SIZE (128 KiB) * SYS_MALLOC_F_LEN = 0x4000 Increase malloc() pool size available before relocation from 8 KiB (default) to 16 KiB. Otherwise "alloc space exhausted" message appears in U-Boot log during board_init_f() stage. There are next reasons for doing so: 1. Having "bootph-all" flags in some dts nodes leads to binding those during pre-relocation stage, and binding (DM) uses dynamic memory allocation 2. clk-exynos850 driver uses CCF clocks, which in turn use dynamic memory allocation Device tree file was imported from Linux kernel. All nodes and boot phase flags added in exynos850-e850-96-u-boot.dtsi are only needed to enable serial console: * oscclk -> cmu_top -> cmu_peri: generate UART/USI clocks * pinctrl_alive and uart1_pins: needed to mux UART pins * pmu_system_controller: configures AP UART path to uart1_pins * usi_uart: configures USI block to operate as a UART protocol * serial_0: enables serial console (UART) [1] https://www.96boards.org/product/e850-96b/ [2] https://www.96boards.org/products/mezzanine/ Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

2023-11-13exynos: Avoid duplicate reset_cpu with SYSRESET enabledSam Protsenko1-0/+2
The sysreset uclass unconditionally provides a definition of the reset_cpu() function. So does the exynos soc code. Fix the build with SYSRESET enabled by omitting the function from the soc code in that case. The code still needs to be kept around for use in SPL.

2021-12-27Finish conversion of CONFIG_SYS_CLK_FREQ to KconfigTom Rini1-2/+3
In order to finish moving this symbol to Kconfig for all platforms, we need to do a few more things. First, for all platforms that define this to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk() and updating a few preprocessor tests. With that done, all platforms that define a value here can be converted to Kconfig, and a fall-back of zero is sufficiently safe to use (and what is used today in cases where code may or may not have this available). Make sure that code which calls this function includes <clock_legacy.h> to get the prototype. Signed-off-by: Tom Rini <trini@konsulko.com>
