2022-10-20imx: kontron-sl-mx8mm: Add support for Kontron Electronics SoM SL i.MX8MM OSM-SFrieder Schrempf
This adds support for the Kontron Electronics SoM SL i.MX8MM OSM-S and the matching baseboard BL i.MX8MM OSM-S. The SoM hardware complies to the Open Standard Module (OSM) 1.0 specification, size S (https://sget.org/standards/osm). The existing board configuration for the non-OSM SoM is reused and allows to detect the SoM variant at runtime.

2022-10-17vbe: Add a test for VBE device tree fixupsSimon Glass
When a FIT includes some OS requests, U-Boot should process these and add the requested info to corresponding subnodes of the /chosen node. Add a pytest for this, which sets up the FIT, runs bootm and then uses a C unit test to check that everything looks OK. The test needs to run on sandbox_flattree since we don't support device tree fixups on sandbox (live tree) yet. So enable BOOTMETH_VBE and disable bootflow_system(), since EFI is not supported on sandbox_flattree. Add a link to the initial documentation. Signed-off-by: Simon Glass <[email protected]>

2022-10-17fdt: Show a message when the working FDT changesSimon Glass
The working FDT is the one which comes from the OS and is fixed up by U-Boot. When the bootm command runs, it sets up the working FDT to be the one it is about to pass to the OS, so that fixups can happen. This seems like an important step, so add a message indicating that the working FDT has changed. This is shown during the running of the bootm command. Signed-off-by: Simon Glass <[email protected]>

2022-09-29dm: core: Allow copying ofnode property data when writingSimon Glass
At present ofnode_write_prop() is inconsistent between livetree and flattree, in that livetree requires the caller to ensure the property value is stable (e.g. in rodata or allocated) but flattree does not, since it makes a copy. This makes the API call a bit painful to use, since the caller must do different things depending on OF_LIVE. Add a new 'copy' argument which tells the function to make a copy if needed. Add some tests to cover this behaviour. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Expand ofnode testsSimon Glass
The current tests do not cover all functions, nor do they cover the new multi-tree functionality. Add and update the tests accordingly and update the 'future work' notes in the documentation. There is a still more testing needed for the failure cases, since at present some ofnode functions return a libfdt error code instead of converting it to an errno. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Add the ofnode multi-tree implementationSimon Glass
Add the logic to redirect requests for the device tree through a function which can look up the tree ID. This works by using the top bits of ofnode.of_offset to encode a tree. It is assumed that there will only be a few device trees used at runtime, typically the control FDT (always tree ID 0) and possibly a separate FDT to be passed the OS. The maximum number of device trees supported at runtime is 8, with this implementation. That would use bits 30:28 of the node-offset value, meaning that the positive offset range is limited to bits 27:0, versus 30:1 with this feature disabled. That still allows a device tree of up to 256MB, which should be enough for most FITs. Larger ones can be supported by using external data with the FIT, or by enabling OF_LIVE. Update the documentation a little and fix up the comment for ofnode_valid(). Signed-off-by: Simon Glass <[email protected]>

2022-09-29test: Make a copy of the device tree before running a testSimon Glass
When the flat device tree changes it can mess up the live tree since that uses the flat tree for its strings. This affects only a few sandbox tests which modify the device tree, but the number will grow as ofnode support for writing improves. While the control FDT is not intended to change while U-Boot is running, some tests do so. For example, the ofnode interface only supports modifying properties in the control FDT, so tests must use that. To solve this problem, keep a copy of the FDT and restore it as needed when the test is finished. The copy only happens on sandbox (except SPL builds), to reduce memory usage and because these tests are not useful on other boards. For other boards, a checksum is taken to ensure that nothing changes. It would be possible to always checksum the FDT on sandbox and only restore it if needed, but this is slightly slower than restoring it every time, at least with crc8. Move the code which checks for success to the very end, for clarity. Signed-off-by: Simon Glass <[email protected]>

2022-09-16blk: Rename HAVE_BLOCK_DEVICESimon Glass
This option is fact really related to SPL. For U-Boot proper we always use driver model for block devices, so CONFIG_BLK is enabled if block devices are in use. It is only for SPL that we have two cases: - SPL_BLK is enabled, in which case we use driver model and blk-uclass.c - SPL_BLK is not enabled, in which case (if we need block devices) we must use blk_legacy.c Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is different enough from BLK and SPL_BLK that there should be no confusion. Signed-off-by: Simon Glass <[email protected]>

2022-09-12Makefile: Add a pcheck option to run tests in parallelSimon Glass
Running tests in parallel is much faster, e.g. 15 seconds to run the tests on sandbox (only), instead of 100 seconds (on a 16-core machine). Add a 'make pcheck' option to access this feature. Note that the tools/ tests still run each tool's tests once after the other, although within that, they do run in parallel. So for example, the buildman tests run in parallel, then the binman tests run in parallel. There would be a signiificant advantage to running them all in parallel together, but that would require a large amount of refactoring, e.g. with more use of pytest fixtures. Update the documentation to represent the current state. Signed-off-by: Simon Glass <[email protected]>

2022-09-02Makefile: Allow LTO to be disabled for a buildSimon Glass
LTO (Link-Time Optimisation) is an very useful feature which can significantly reduce the size of U-Boot binaries. So far it has been made available for selected ARM boards and sandbox. However, incremental builds are much slower when LTO is used. For example, an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7 seconds with LTO enabled. Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be disabled during development if needed, for faster builds. Add some documentation about LTO while we are here.
