99 * The flash can be mapped either as read-only or read-write.
100 *
101 * If it is read-write then it should also be mapped as device memory because
102 * NOR flash programming involves sending a fixed, ordered sequence of commands.
103 *
104 * If it is read-only then it should also be mapped as:
105 * - Normal memory, because reading from NOR flash is transparent, it is like
106 * reading from RAM.
107 * - Non-executable by default. If some parts of the flash need to be executable
108 * then platform code is responsible for re-mapping the appropriate portion
109 * of it as executable.
