CONFIG_STANDALONE_LOAD_ADDR has been used for examples/standalone but not for examples/api. The suitability of an address to load an ELF binary and run it does not only depend on the architecture but also on the memory layout of the board which is not reflected in the default value of CONFIG_STANDALONE_LOAD_ADDR. Commit32b7e39db4("Convert CONFIG_STANDALONE_LOAD_ADDR to Kconfig") set the default on RISC-V to 0x0 though most boards used 0x80200000 before the patch. On most boards we can assume 8 MiB of memory available above $loadaddr. So we can safely use $loadaddr + 4 MiB as load address for the standalone example and eliminate CONFIG_STANDALONE_LOAD_ADDR altogether.
