----------------------------------------------------------------
TPM devices generally have a builtin RNG. When booting via EFI the 
Linux kernel relies on EFI_RNG_PROTOCOL for enabling KASLR.

Adjust the driver model and expose functions to retrieve a random number.
With the above changes the EFI subsystem can install the EFI_RNG_PROTOCOL
even if the target hardware only has a TPM, but no other RNG.

----------------------------------------------------------------
Ilias Apalodimas (1):
      efi_loader: initialize the RNG protocol after the TCC2

Simon Glass (1):
      tpm: Export the TPM-version functions

Sughosh Ganu (6):
      tpm: rng: Add driver model interface for TPM RNG device
      tpm: Add the RNG child device
      cmd: rng: Add support for selecting RNG device
      cmd: rng: Use a statically allocated array for random bytes
      doc: rng: Add documentation for the rng command
      test: rng: Add a UT testcase for the rng command
