2022-09-29dm: core: Add definitions for multiple ofnode treesSimon Glass
At present, unless OF_LIVE is enabled, ofnode only supports access to one device tree, the control FDT. This is because only the node offset is encoded in ofnode, with the tree being implicit. This makes ofnode (without OF_LIVE) unsuitable for device tree fixups, as implemented by ft_board_setup() and other such functions. To solve this, we can use the top bits of the node offset to hold a tree ID. Add the definitions for this. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Split ofnode_path_root() into two functionsSimon Glass
This function turns out to be a little confusing since it looks up a path and also registers the tree. Split it into two, one that gets the root node and one that looks up a path, so the purpose is clear. Registering the tree will happen in a function to be added in a later patch, called oftree_from_fdt(). Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Allow obtaining a node offset in the same treeSimon Glass
In some cases we want to obtain an ofnode in the same tree as a different ofnode, such as when looking up a subnode. At present this is trivial, since there is only one tree. When there are multiple trees, this implementation will change. Also move the ofnode_to_offset() function up higher in the header file, since we will need to provide a different implementation with multiple trees. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Add a way to look up a phandle in an oftreeSimon Glass
When we have multiple trees, the ofnode logic needs to be told which one to use. Create a new function which takes an oftree argument, along with a helper to obtain the FDT pointer from an oftree. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Add an ofnode function to obtain the flat treeSimon Glass
The flat device tree is assumed to be the control FDT but this is not always the case. Update the ofnode implementation to obtain the node via an function call so we can eventually add support for selecting different trees. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Expand integer-reading testsSimon Glass
The current tests do not cover all the behaviour. Add some more. Tidy up a few inconsistencies between livetree and flattree which come to light with these tests. Also drop the -ENODATA error since it is never actually returned. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Drop ofnode_is_available()Simon Glass
This function is also available as ofnode_is_enabled(), so use that instead. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Avoid creating a name property when unflatteningSimon Glass
The current implementation creates a 'name' value for every node. This is not needed for the latest device tree format, which includes a name in the node header. Adjust the code to point the name at the node header instead. Also simplify ofnode_get_name(), now that we can rely on it to set the name correctly. Update the comment to make it clear what name the root node has. Signed-off-by: Simon Glass <[email protected]>
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: Rename ofnode_get_first/next_property()Simon Glass
Drop the 'get' in these names since it does not fit with the rest of the API. Signed-off-by: Simon Glass <[email protected]>
2022-09-29dm: core: Reduce code size with dev_of_offset()Simon Glass
Update the function to mark it with the const attribute. Also avoid calling it multiple times in the devfdt_get_addr_index() function. 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]>

2022-09-27watchdog: max6370: use __udelay() to avoid recursionPali Rohár
The udelay() function in lib/time.c contains a WATCHDOG_RESET() call. So use __udelay() in max6370_wdt.c to prevent recursion. Fixes: 0a095fc53b15 ("watchdog: Add MAX6370 watchdog timer driver") Signed-off-by: Pali Rohár <[email protected]> Reviewed-by: Stefan Roese <[email protected]>
2022-09-27watchdog: gpio_wdt: use __udelay() to avoid recursionRasmus Villemoes
The udelay() function in lib/time.c contains a WATCHDOG_RESET() call. The only reason this doesn't lead to a catastrophic infinite recursion is due to the rate-limiting in wdt-uclass.c: if (time_after_eq(now, priv->next_reset)) { priv->next_reset = now + priv->reset_period; wdt_reset(dev); } But this would fall apart if ->next_reset was updated after calling the device's reset method. This is needlessly fragile, and it's easy enough to avoid that recursion in the first place by just using __udelay() directly.

2022-09-23ddr: fsl: Allow to detect 4 GB DDR modules in 32-bit modePali Rohár
U-Boot core code already handles the case when RAM size is bigger than CONFIG_MAX_MEM_MAPPED. So there is no need to do duplicate check in fsl ddr driver for CONFIG_MAX_MEM_MAPPED. Instead simplify code to just check if RAM size can be representable in phys_size_t type. And avoid printing warning if phys_size_t is just 1 byte smaller than RAM size, which is the typical situation with 4 GB DDR module. Signed-off-by: Pali Rohár <[email protected]>
2022-09-23ddr: fsl: Fix fsl_ddr_sdram_size() for 4GB modules with 32-bit phys_size_tPali Rohár
Function fsl_ddr_compute() always return size in unsigned long long type, but function fsl_ddr_sdram_size() returns size in phys_size_t type. When 36-bit addressing mode is not enabled then phys_size_t type is only 32-bit and thus it cannot store value 4GB (0x100000000). Function fsl_ddr_sdram_size() in this case returns truncated value 0x0. Fix this issue by returning the highest representable value, which is 0xffffffff (4GB - 1 byte). This change fixes crashing of proper U-Boot because it detected 4 GB module as RAM with zero size. Signed-off-by: Pali Rohár <[email protected]>
