To: u-boot
From: Reinhard Pfau <pfau@gdsys.de>
Extend the tpm library with support for single authorized (AUTH1) commands
as specified in the TCG Main Specification 1.2. (The internally used helper
functions are implemented in a way that they could also be used for double
authorized commands if someone needs it.)
Provide enums with the return codes from the TCG Main specification.
For now only a single OIAP session is supported.
OIAP authorized version of the commands TPM_LoadKey2 and TPM_GetPubKey are
provided. Both features are available using the 'tpm' command, too.
Authorized commands are enabled with CONFIG_TPM_AUTH_SESSIONS. (Note that
this also requires CONFIG_SHA1 to be enabled.)

To: u-boot
From: Dirk Eibach <eibach@gdsys.de>
The gdsys ControlCenter Digital board is based on a Freescale P1022 QorIQ SOC.
It boots from SPI-Flash but can be configured to boot from SD-card for
factory programming and testing.
On board peripherals include:
- 2x GbE
- Lattice ECP3 FPGA connected via PCIe
- mSATA RAID1
- USB host
- DisplayPort video output
- Atmel TPM

Changes in v6:
- Add CONFIG_PCI_INDIRECT_BRIDGE to controlcenterd.h
- Add MAINTAINERS entry
- drop "mpc85xx: Add CONFIG_RELEASE_CORE0_ONLY" and use mp_holdoff instead
Changes in v5:
- avoid probing dp501 i2c bridge addresses
Changes in v4: None
Changes in v3:
- fix email addresses
Changes in v2:
- configuration for SPI builds was missing
- whitespace fixes
