The MEMORY block in the linker script doesn't define a section or
segment; it describes a region of memory that's available for
placement of sections. If you specify attributes, the linker uses them
to decide whether a section is eligible to be placed in that memory
region, but it's the attributes of the sections themselves that
determine the attributes of the output section.
