* board: Rename uclass to sysinfoSimon Glass2020-11-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This uclass is intended to provide a way to obtain information about a U-Boot board. But the concept of a U-Boot 'board' is the whole system, not just one circuit board, meaning that 'board' is something of a misnomer for this uclass. In addition, the name 'board' is a bit overused in U-Boot and we want to use the same uclass to provide SMBIOS information. The obvious name is 'system' but that is so vague as to be meaningless. Use 'sysinfo' instead, since this uclass is aimed at providing information on the system. Rename everything accordingly. Note: Due to the patch delta caused by the symbol renames, this patch shows some renamed files as being deleted in one place and created in another.

* dm: test: Disable some tests that should not run in SPLSimon Glass2020-10-291-4/+7
| | | | | | | | | | | Tests are easier to run in U-Boot proper. Running them in SPL does not add test coverage in most cases. Also some tests use features that are not available in SPL. Update the build rules to disable these tests in SPL. We still need test-main to be able to actually run SPL tests. Signed-off-by: Simon Glass <sjg@chromium.org>

* test: pinmux: Add test for pin muxingSean Anderson2020-10-081-0/+3
| | | | | | | | | | | | | | | | | This extends the pinctrl-sandbox driver to support pin muxing, and adds a test for that behaviour. The test is done in C and not python (like the existing tests for the pinctrl uclass) because it needs to call pinctrl_select_state. Another option could be to add a command that invokes pinctrl_select_state and then test everything in test/py/tests/test_pinmux.py. The pinctrl-sandbox driver now mimics the way that many pinmux devices work. There are two groups of pins which are muxed together, as well as four pins which are muxed individually. I have tried to test all normal paths. However, very few error cases are explicitly checked for. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* firmware: add SCMI agent uclassEtienne Carriere2020-09-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces SCMI agent uclass to interact with a firmware using the SCMI protocols [1]. SCMI agent uclass currently supports a single method to request processing of the SCMI message by an identified server. A SCMI message is made of a byte payload associated to a protocol ID and a message ID, all defined by the SCMI specification [1]. On return from process_msg() method, the caller gets the service response. SCMI agent uclass defines a post bind generic sequence for all devices. The sequence binds all the SCMI protocols listed in the FDT for that SCMI agent device. Currently none, but later change will introduce protocols. This change implements a simple sandbox device for the SCMI agent uclass. The sandbox nicely answers SCMI_NOT_SUPPORTED to SCMI messages. To prepare for further test support, the sandbox exposes a architecture function for test application to read the sandbox emulated devices state. Currently supports 2 SCMI agents, identified by an ID in the FDT device name. The simplistic DM test does nothing yet. SCMI agent uclass is designed for platforms that embed a SCMI server in a firmware hosted somewhere, for example in a companion co-processor or in the secure world of the executing processor. SCMI protocols allow an SCMI agent to discover and access external resources as clock, reset controllers and more. SCMI agent and server communicate following the SCMI specification [1]. This SCMI agent implementation complies with the DT bindings defined in the Linux kernel source tree regarding SCMI agent description since v5.8.
