cmd: fdt: Add support for reading stringlist property values

2022-09-21T08:37:46+00:00

The fdt command currently handles stringlists as strings in 'fdt get value'
subcommand. Since strings in FDT stringlists are separated by '\0', only
the first value gets inserted into the environment variable passed to the
'fdt get value' command.

Example, consider the following DT snippet:

/ { compatible = "foo", "bar" };

The following command only reports the first string in stringlist:
=> fdt get value var / compatible ; print var
foo

It is not possible to assign list of null-terminated strings into U-Boot
environment variable. Add optional 'index' parameter to the subcommand
'fdt get value    []' which lets user specify which
string within the stringlist should be assigned into the 'var' variable.
The default value of 'index' is 0 in case it is not present. This way the
'fdt' command API does not change and existing scripts are not broken.

The following command now reports the Nth string in stringlist, counting
from zero:
=> fdt get value var / compatible 1 ; print var
bar

cmd: mvebu/bubt: Check for A38x/A37xx OTP secure bits and secure boot

2022-09-13T04:38:08+00:00

For obvious reasons BootROMS rejects unsigned images when secure boot is
enabled in OTP secure bits. So check for OPT secure bits and do not allow
flashing unsigned images when secure boot is enabled. Access to OTP via
U-Boot fuse API is currently implemented only for A38x and A37xx SoCs.

Additionally Armada 3700 BootROM rejects signed trusted image when secure
boot is not enabled in OTP. So add also check for this case. On the other
hand Armada 38x BootROM acceps images with secure boot header when secure
boot is not enabled in OTP.

OTP secure bits may have burned also boot device source. Check it also and
reject flashing images to target storage which does not match OTP.

cmd: mvebu/bubt: Check for A38x image data checksum

2022-09-13T04:38:08+00:00

Currently for A38x image is checked only header checksum.
So check also for image data checksum to prevent flashing broken image.

cmd: fix tftpput command

2022-09-09T14:07:54+00:00

Calling tftpput with less than 2 arguments must lead to a failure.

If tftpput is called with two arguments, these are the address and
the size of the file to be transferred.

tpm: Allow reporting the internal state

2022-09-03T13:59:05+00:00

It is useful to read information about the current TPM state, where
supported, e.g. for debugging purposes when verified boot fails.

Add support for this to the TPM interface as well as Cr50. Add a simple
sandbox test.

tpm: Require a digest source when extending the PCR

2022-09-03T13:53:58+00:00

This feature is used for measured boot, so we can add a log entry to the
TCPA with some information about where the digest comes from. It is not
currently supported in the TPM drivers, but add it to the API so that
code which expects it can signal its request.
