net: Add new wol command - Wake on LAN

2018-07-02T19:14:20+00:00

Add a new command 'wol': Wait for an incoming Wake-on-LAN packet or
time out if no WoL packed is received.
If the WoL packet contains a password, it is saved in the environment
variable 'wolpassword' using the etherwake format (dot or colon
separated decimals).

Intended use case: a networked device should boot an alternate image.
It's attached to a network on a client site, modifying the DHCP server
configuration or setup of a tftp server is not allowed.
After power on the device waits a few seconds for a WoL packet. If a
packet is received, the device boots the alternate image. Otherwise
it boots the default image.

This method is a simple way to interact with a system via network even
if only the MAC address is known. Tools to send WoL packets are
available on all common platforms.

Some Ethernet drivers seem to pad the incoming packet. The additional
padding bytes might be recognized as Wake-on-LAN password bytes.

By default enabled in pengwyn_defconfig.

  avb is_unlocked - check device lock state
  avb get_uuid - read and print uuid of a partition
  avb read_part - read data from partition
  avb read_part_hex - read data from partition and output to stdout
  avb write_part - write data to partition
  avb verify - run full verification chain

tpm: prepare support for TPMv2.x commands

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.

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.

cmd: Add command for calculating binary operations

2018-04-07T00:45:44+00:00

This patch adds a command that enables the calculation of bit operations
(AND, OR, XOR) on binary data from the command line. Memory locations as
well as the contents of environment variables are eligible as sources
and destination of the binary data used in the operations.

The possible applications are manifold: Setting specific bits in
registers using the regular read-OR-write pattern, masking out bits in
bit values, implementation of simple OTP encryption using the XOR
operation, etc.
