Embedded flash can have user signature area on SAMv7. This is a 512 bytes large page whose data are not erased by asserting ERASE pin or by software ERASE command. This commit adds arch to board interface for this area. It is possible to perform read, write and erase operation. SAMV7_USER_SIGNATURE option has to be set in the configuration.
