tpm: add a Sandbox TPMv2.x driver

2018-05-26T00:13:00+00:00

This driver can emulate all the basic functionalities of a TPMv2.x
chip and should behave like them during regular testing.

tpm2: tis_spi: add the possibility to reset the chip with a gpio

2018-05-26T00:12:59+00:00

On some designs, the reset line could not be connected to the SoC reset
line, in this case, request the GPIO and ensure the chip gets reset.

tpm: prepare support for TPMv2.x commands

2018-05-26T00:12:55+00:00

Choice between v1 and v2 compliant functions is done with the
configuration.

Create the various files that will receive TPMv2-only code on the same
scheme as for the TPMv1 code.

tpm: disociate TPMv1.x specific and generic code

2018-05-26T00:12:55+00:00

There are no changes in this commit but a new organization of the code
as follow.

* cmd/ directory:
        > move existing code from cmd/tpm.c in cmd/tpm-common.c
	> move specific code in cmd/tpm-v1.c
	> create a specific header file with generic definitions for
	  commands only called cmd/tpm-user-utils.h

* lib/ directory:
        > move existing code from lib/tpm.c in lib/tpm-common.c
	> move specific code in lib/tpm-v1.c
	> create a specific header file with generic definitions for
	  the library itself called lib/tpm-utils.h

* include/ directory:
        > move existing code from include/tpm.h in include/tpm-common.h
	> move specific code in include/tpm-v1.h

Code designated as 'common' is compiled if TPM are used. Code designated
as 'specific' is compiled only if the right specification has been
selected.

All files include tpm-common.h.
Files in cmd/ include tpm-user-utils.h.
Files in lib/ include tpm-utils.h.
Depending on the specification, files may include either (not both)
tpm-v1.h or tpm-v2.h.

tpm: prepare introduction of TPMv2.x support in Kconfig

2018-05-26T00:12:33+00:00

Because both major revisions are not compatible at all, let's make them
mutually exclusive in Kconfig. This way we will be sure, when using a
command or a library function that it is supported by the right
revision.

Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x
files by "tpm2_" to make the distinction without moving everything.

The Kconfig menu about TPM drivers is now divided into two sections, one
for each specification. Compliant drivers with one specification will
only show up if this specification _only_ has been selected, otherwise a
comment is displayed.

Once a driver is selected by the user, it selects automatically a
boolean value, that is needed in order to activate the TPM commands.
Selecting the TPM commands will automatically select the right
command/library files.

tpm: add Revision ID field in the chip structure

2018-05-25T12:12:40+00:00

TPM are shipped with a few read-only register from which we can retrieve
for instance:
- vendor ID
- product ID
- revision ID

Product and vendor ID share the same register and are already referenced
in the tpm_chip structure. Add the revision ID entry which is missing.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48+00:00

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.
