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.
