CONFIG_SPL_BSS_START_ADDR is only used on a few mach- linker scripts. stm32mp1 uses the generic script under arch/arm/cpu/u-boot-spl.lds, which does not make use of this definition.
The SPL BSS starts in SRAM, right after .text, .rodata, .data, and .u_boot_list. A very short version of the STM32MP1 memory map is:
- SYSRAM: 2ffc0000 - 30000000 <- all of SPL is here
- DRAM: c0000000+
0xC0200000 is a DRAM address, and has nothing to do with SPL. It is just very misleading to have it next to CONFIG_SPL_BSS_MAX_SIZE, or to have it at all.
