f3s_v2unlockall()

int f3s_v2unlockall (f3s_dbase_t *dbase,
                     f3s_access_t *access,
                     uint32_t flags,
                     uint32_t text_offset);

This function clears all write-protected blocks on the device containing the address text_offset. Some boards use multiple chips to form one single logical device. In this situation, each chip will have f3s_v2unlockall() invoked on it separately.

On success, it should return EOK. If an error occurs, it should return one of the following:

EIO

Recoverable I/O error (e.g. failed due to low power or unlock failed, but corruption is localized and block will be usable after an erase).

EFAULT

Unrecoverable I/O error (e.g. block no longer usable).

EINVAL

Invalid command error.

ERANGE

Flash memory access out of range (via service->page function).

ENODEV

Flash no longer accessible (e.g. flash removed).

ESHUTDOWN

Critical error; shut down the flash driver.
