|
|
* There are four request types that are applicable for rpmb accesses- two
|
|
* under read category and two under write. They are
|
|
*
|
|
* Reads
|
|
* -------
|
|
* 1. Read Write Counter
|
|
* 2. Authenticated data read
|
|
*
|
|
*
|
|
* Writes
|
|
* -------
|
|
* 1. Provision RPMB key (though it might be done in a secure environment)
|
|
* 2. Authenticated data write
|
|
*
|
|
* While its given that the rpmb data frames are going to have that
|
|
* information encoded in it and the frames should be generated by a secure
|
|
* piece of code, the request types can be classified as above.
|
|
*
|
|
* So here are the set of commands that should be executed atomically in the
|
|
* ioctl for rpmb read operation
|
|
* 1. Switch partition
|
|
* 2. Set block count
|
|
* 3. Write data frame - CMD25 to write the rpmb data frame
|
|
* 4. Set block count
|
|
* 5. Read the data - CMD18 to do the actual read
|
|
*
|
|
* Similarly for rpmb write operation, these are the commands that should be
|
|
* executed atomically in the ioctl for rpmb write operation
|
|
* 1. Switch partition
|
|
* 2. Set block count
|
|
* 3. Write data frame - CMD25 to write the rpmb data frame with data
|
|
* 4. Set block count
|
|
* 5. Read the data - CMD25 to write rpmb data frame indicating that rpmb
|
|
* result register is about to be read
|
|
* 6. Set block count
|
|
* 7. Read rpmb result - CMD18 to read the rpmb result register
|
|
*
|
|
* Each of the above commands should be sent individually via struct mmc_ioc_cmd
|
|
* and fields like is_acmd that are not needed for rpmb operations will be
|
|
* ignored.
