2022-09-29dm: core: Rename ofnode_get_property_by_prop()Simon Glass
The current name is quite unwieldy. Change it to use an ofprop_ prefix and shorten it. Fix the return-value comment while we are here. Signed-off-by: Simon Glass <[email protected]>

2022-09-29dm: core: Drop the const from ofnodeSimon Glass
Now that we support writing to ofnodes, the const is not accurate. Drop it to avoid undesirable casting. Also drop the ofnode_to_npw() which is now the same as ofnode_to_np(). Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Support writing a property to an empty nodeSimon Glass
At present this does not work with livetree. Fix it and add a test. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Allow adding ofnode subnodesSimon Glass
Add this feature to the ofnode interface, supporting both livetree and flattree. If the node exists it is returned, along with a -EEXIST error. Update the functions it calls to handle this too. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Pass a root node to of_find_node_by_phandle()Simon Glass
This function currently assumes that the control FDT is used. Update it to allow a root node to be passed, so it can work with any tree. Also add a comment to ofnode_get_by_phandle() so that its purpose is clear. Signed-off-by: Simon Glass <[email protected]>

Add a new function to write an integer to an ofnode (live tree or flat tree). Signed-off-by: Simon Glass <[email protected]>
2022-08-12dm: core: Allow writing to a flat tree with ofnodeSimon Glass
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 <[email protected]>
2022-08-12dm: core: Swap parameters of ofnode_write_prop()Simon Glass
It is normal for the length to come after the value in libfdt. Follow this same convention with ofnode. Signed-off-by: Simon Glass <[email protected]>
2022-08-12dm: core: Introduce support for multiple treesSimon Glass
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 <[email protected]>

2022-06-28dm: core: Support accessing core tagsSimon Glass
At present tag numbers are only allocated for non-core data, meaning that the 'core' data, like priv and plat, are accessed through dedicated functions. For debugging and consistency it is convenient to use tags for this 'core' data too. Add support for this, with new tag numbers and functions to access the pointer and size for each. Update one of the test drivers so that the uclass-private data can be tested here. There is some code duplication with functions like device_alloc_priv() but this is not addressed for now. At some point, some rationalisation may help to reduce code size, but more thought it needed on that. Signed-off-by: Simon Glass <[email protected]>
2022-06-28dm: core: Fix addresses in the dm static commandSimon Glass
This command converts pointers to addresses, but the pointers being converted are in the image's rodata region.

Introduce DM_FLAG_PROBE_AFTER_BIND flag, which can be set by driver or uclass in .bind(), to indicate such driver instance should be probe()d once binding of all devices is complete. This is useful in case the driver determines that hardware initialization is mandatory on boot, and such initialization happens only in probe(). This also solves the inability to call device_probe() from .bind().

2022-04-25Merge branch '2022-04-25-initial-implementation-of-stdboot'Tom Rini
To quote the author: The bootflow feature provide a built-in way for U-Boot to automatically boot an Operating System without custom scripting and other customisation. This is called 'standard boot' since it provides a standard way for U-Boot to boot a distro, without scripting. It introduces the following concepts: - bootdev - a device which can hold a distro - bootmeth - a method to scan a bootdev to find bootflows (owned by U-Boot) - bootflow - a description of how to boot (owned by the distro) This series provides an implementation of these, enabled to scan for bootflows from MMC, USB and Ethernet. It supports the existing distro boot as well as the EFI loader flow (bootefi/bootmgr). It works similiarly to the existing script-based approach, but is native to U-Boot. With this we can boot on a Raspberry Pi 3 with just one command: bootflow scan -lb which means to scan, listing (-l) each bootflow and trying to boot each one (-b). The final patch shows this. With a standard way to identify boot devices, booting become easier. It also should be possible to support U-Boot scripts, for backwards compatibility only. ... The design is described in these two documents: https://drive.google.com/file/d/1ggW0KJpUOR__vBkj3l61L2dav4ZkNC12/view?usp=sharing https://drive.google.com/file/d/1kTrflO9vvGlKp-ZH_jlgb9TY3WYG6FF9/view?usp=sharing

2022-04-18dm: core: Deal with a wrinkle with linker listsSimon Glass
When every member of a linker list is aligned by the compiler, we can no longer rely on the sizeof of the struct to determine the number of entries. For example, if the struct size is 0x90 but every entry is aligned to 0xa0 by the compiler, the linker list entries takes more space in memory and the calculation of the number of entries is incorrect. For example, we may see 0x12 entries when there are only 0x11. This is a real problem. There may be a general solution, although I cannot currently think of one. So far it only bites with OF_PLATDATA_RT which creates a pointer to each entry of the 'struct udevice' linker_list. This does not happen without that option, so it only affects SPL. Work around it by manually calculating the aligned size of struct udevice, then using that for the n_ent calculation.
