ram: stm32mp1: bound the invalid-argument message in stm32mp1_ddr_subcmd()

2026-08-31T08:01:44Z

stm32mp1_ddr_subcmd() formats a rejected argument into a 50-byte stack buffer with an unbounded sprintf(): char string[50] = ""; ... sprintf(string, "invalid argument %s", argv[1]); argv[1] comes from cli_simple_parse_line() over a console line held in buffer[CONFIG_SYS_CBSIZE], which is commonly 256 bytes or more. The fixed prefix takes 17 bytes, leaving 32 for the argument and its NUL, so any invalid argument longer than 32 characters writes past the end of string and corrupts the stack of the DDR interactive console. Use snprintf() with sizeof(string). The sibling call a few lines below formats only integers and cannot overflow, so it is left alone.

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22Z

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.

ram: stm32mp1: Add STM32MP13xx support

2025-06-11T07:42:56Z

Add support for configuring DRAM controller on STM32MP13xx SoC. The DRAM controller is basically identical to the DWC controller on STM32MP15xx SoC, except the bus width is reduced from 32bit to 16bit and a few registers and bits are therefore not present. Handle the difference by factoring these parts out. Use IS_ENABLE() as much as possible to assure code which is not enabled on builds for a single SoC gets compiled out. Handle the different offset of RCC_DDRITFCR register and missing DDRC2 clock the same way. Signed-off-by: Marek Vasut
