Introduce syscalls:
- TK1_SYSCALL_PRELOAD_STORE
- TK1_SYSCALL_PRELOAD_STORE_FIN
- TK1_SYSCALL_PRELOAD_DELETE
- TK1_SYSCALL_REG_MGMT = 11
Change preload_store_finalize() not to take USS arg. Unused for
preloaded apps.
Adds syscalls:
- ALLOCATE_AREA
- DEALLOCATE_AREA
- WRITE_DATA
- READ_DATA
and code to access the filesystem and the flash over SPI.
Based on original work by Daniel Jobson <jobson@tillitis.see> for
these files:
- auth_app.[ch]
- flash.[ch]
- spi.[ch]
- partition_table.[ch]
- rng.[ch]
- storage.[ch]
which are used with small changes to integrate with the new syscall
method.

Build firmware, testfw and testapp using tkey-libs:
https://github.com/tillitis/tkey-libs
In an effort not to have more or less identical code maintained in two
places, use tkey-libs when developing firmware, testfw and the
firmware testapp, too.
You can place the Git directory directly under hw/application_fpga
and then an ordinary make should work.
Or build with:
make LIBDIR=/path/to/tkey-libs

Introduce new syscall TK1_SYSCALL_GET_VIDPID to get Vendor ID and
Product ID from the protected Unique Device Identification number.
UDI is protected from device apps to protect the serial number, so
apps won't know the exact TKey they are running on other than the CDI.
It may, however, be important to know what *kind* of TKey they are
running on, so we want to expose the Vendor ID and Product ID.
- fpga: Allow UDI to be read when doing syscalls.
- Add the new syscall to firmware.
- Add test to testapp directly after negative test of reading UDI to
read out VID/PID through a syscall.
