tpm: Allow reporting the internal state

2022-09-03T13:59:05Z

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. Signed-off-by: Simon Glass Reviewed-by: Ilias Apalodimas Signed-off-by: Ilias Apalodimas

dm: core: Add support for writing u32 with ofnode

2022-08-12T12:14:24Z

Add a new function to write an integer to an ofnode (live tree or flat tree). Signed-off-by: Simon Glass

dm: core: Allow writing to a flat tree with ofnode

2022-08-12T12:14:24Z

In generally it is not permitted to implement an ofnode function only for flat tree or live tree. Both must be supported. Also the code for live tree access should be in of_access.c rather than ofnode.c which is really just for holding the API-conversion code. Update ofnode_write_prop() accordingly and fix the test so it can work with flat tree too. Signed-off-by: Simon Glass

dm: core: Tidy up ofnode-writing test

2022-08-12T12:14:24Z

Update this test to use the livetree flag so that special check can be avoided. Also drop a few blank lines. Signed-off-by: Simon Glass

dm: core: Swap parameters of ofnode_write_prop()

2022-08-12T12:14:24Z

It is normal for the length to come after the value in libfdt. Follow this same convention with ofnode. Signed-off-by: Simon Glass

dm: core: Move ofnode-writing test to ofnode

2022-08-12T12:14:24Z

This fits better in the ofnode tests, so move it. Signed-off-by: Simon Glass

dm: core: Introduce support for multiple trees

2022-08-12T12:14:23Z

At present ofnode only works with a single device tree, for the most part. This is the control FDT used by U-Boot. When booting an OS we may obtain a different device tree and want to modify it. Add some initial support for this into the ofnode API. Note that we don't permit aliases in this other device tree, since the of_access implementation maintains a list of aliases collected at start-up. Also, we don't need aliases to do fixups in the other FDT. So make sure that flat tree and live tree processing are consistent in this area. Signed-off-by: Simon Glass

test: rng: Add a UT testcase for the rng command

2022-08-02T20:50:02Z

The 'rng' command dumps a number of random bytes on the console. Add a set of tests for the 'rng' command. The test function performs basic sanity testing of the command. Since a unit test is being added for the command, enable it by default in the sandbox platforms.

watchdog: add pulse support to gpio watchdog driver

2022-07-21T06:09:06Z

A common external watchdog circuit is kept alive by triggering a short pulse on the reset pin. This patch adds support for this use case, while making the algorithm configurable in the devicetree. The "linux,wdt-gpio" driver being modified is based off the equivalent driver in the Linux kernel, which provides support for this algorithm. This patch brings parity to this driver, and is kept aligned with the functionality and devicetree configuration in the kernel. It should be noted that this adds a required property named 'hw_algo' to the devicetree binding, following suit with the kernel. I'm happy to make this backward-compatible if preferred.
