[Skiboot] [PATCH v2 00/31] Add libstb and its dependencies

[Claudio Carvalho]

Libstb provides an API for secure and trusted boot. This API can be used to add
secure and trusted boot support for the platforms. Habanero is our first
target.

This patch series adds the libstb and all its dependencies.

The first three patches add an initial libstb documentation

The following patches add the libstb dependencies:
* ROM code driver
* I2C Nuvoton TPM 2.0 device driver
* TCG Software Stack implementation
* Event log manager implementation

The last patch adds the libstb interface, which is defined in libstb/stb.h

Changelog v2:
- reordered patches - reported by Balbir Singh
- fixed documentation typos - reported by George Wilson
- overall documentation update
- converted the documentation to ReStructured Text format - reported by Stewart
  Smith
- fixed braces to be compliant with kernel's brace style - reported by Oliver
  O'Halloran and George Wilson
- renamed memcpy_ci() to memcpy_from_ci() and refactored its code - reported by
  Oliver O'Halloran
- removed strnlen() patch. It's a good function to have, but no longer needed
  by secure and trusted boot code
- added size_t parameter to the container header helpers for sanity check -
  reported by Stewart Smith
- made container header code endian safe by using be16/be32/b364 types and
  be*_to_cpu() - reported by Stewart Smith
- renamed tpm.{c,h} to tpm_chip.{c,h}
- refactored tpm_register_chip() in tpm_chip.c. TPM chip id is no longer based
  on the label property. If tpm_register_chip() fails, it just disables the tpm
  devtree node as opposed to abort the boot. Removed label property from device
  tree documentation.
- Inverted the digest order for events added by skiboot in the event log.
  SHA512 comes first, same as Hostboot events.
- removed STB_SUCCESS macro - reported by Stewart Smith
- splitted out the base Hostboot rom_entry.S code - reported by George Wilson
- splitted out the base Hostboot TSS and tpmLogMgr code - reported by George
  Wilson
- splitted the Nuvoton TPM device driver patch into smaller patches - reported
  by George Wilson
- splitted out the I2C functions from the Nuvoton TPM device driver by creating
  the tpm_i2c_interface.{c.h}.
