Three supported SH4/SH4A boards with the bootloader image stored on SPI flash have own flavour of a linker script, in turn they are equal among each other. The only difference is that the text from lowlevel_init.o is placed right after start.o, which makes sense. Note that .bss section is not marked as NOLOAD, because for about 10 years this is a default option of a GNU linker, either the attribute is found or not the resulting image file is the same.
