In certain TI SoCs, on the CPSW and ICSS peripherals, there is a possibility that the MDIO interface returns corrupt data on MDIO reads or writes incorrect data on MDIO writes. There is also a possibility for the MDIO interface to become unavailable until the next peripheral reset. The workaround is to configure the MDIO in manual mode and disable the MDIO state machine and emulate the MDIO protocol by reading and writing appropriate fields in MDIO_MANUAL_IF_REG register of the MDIO controller to manipulate the MDIO clock and data pins. More details about the errata i2329 and the workaround is available in: https://www.ti.com/lit/er/sprz487a/sprz487a.pdf Add implementation to disable MDIO state machine, configure MDIO in manual mode and provide software MDIO read and writes via MDIO bitbanging. Allow the MDIO to be initialized based on the need for manual mode. Signed-off-by:

When MMU is already enabled then dcache_enable() does not call mmu_setup() and so setup_all_pgtables() is also never called. In this situation when some driver calls mmu_set_region_dcache_behaviour() function then U-Boot crashes with error message: Emergency page table not setup. Fix this issue by explicitly calling setup_all_pgtables() in dcache_enable() function near condition for mmu_setup(). This change fixes chainloading U-Boot from U-Boot on Turris Mox board which uses mvneta ethernet driver which calls mmu_set_region_dcache_behaviour().

VHV gpio is connected to MCU and only on updated board design. Without it eFUSE programming does not work. Omnia MCU driver exports this GPIO to U-Boot under name mcu_56 and only when it is supported by MCU. So U-Boot fuse command refuse eFUSE programming on older board design when VHV gpio is not available. We tested that Armada 385 without connected VHV gpio can do eFUSE programming but only for some bits and only sometimes - it is unstable. And better to be disabled on older board design without VHV gpio support. Signed-off-by: -
VHV_Enable GPIO is required to enable during eFuse programming on Armada SoCs not from 3700 family. Add support for enabling and disabling VHV pin via GPIO during eFuse programming, when specified. All details are in Marvell AN-389: ARMADA VHV Power document (Doc. No. MV-S302545-00 Rev. C, August 2, 2016). Note that due to HW Errata 3.6 eFuse erroneous burning (Ref #: HWE-3718342) VHV power must be disabled while core voltage is off to prevent erroneous eFuse programming. This is specified in Marvell ARMADA 380/385/388 Functional Errata, Guidelines, and Restrictions document (Doc. No. MV-S501377-00 Rev. D, December 1, 2016). Signed-off-by: -
This patch implements LD eFuse programming support. Armada 385 contains two LD eFuse lines, each is 256 bit long with one additional lock bit. LD 0 line is mapped to U-Boot fuse bank 64 and LD 1 line to fuse bank 65. U-Boot 32-bit fuse words 0-8 are mapped to LD eFuse line bits 0-255. U-Boot fuse word 9 is mapped to LD eFuse line lock bit. So to program LD 1 General Purpose Data line, use U-Boot fuse command: => fuse prog -y 65 0 0x76543210 => fuse prog -y 65 1 0xfedcba98 => fuse prog -y 65 2 0x76543210 => fuse prog -y 65 3 0xfedcba98 => fuse prog -y 65 4 0x76543210 => fuse prog -y 65 5 0xfedcba98 => fuse prog -y 65 6 0x76543210 => fuse prog -y 65 7 0xfedcba98 => fuse prog -y 65 8 0x1 Signed-off-by: -

When the imx8mn.dtsi file was pulled in from Linux, the UARTs were moved into an spba sub-node which wasn't being included in the SPL device tree. This meant the references to the UART weren't being handled properly and when booting the system would constantly reboot. Fix this by adding the spba node to the spl device tree to restore normal booting. Based on the patch from Adam Ford for the imx8mn-beacon-kit-u-boot board.

To quote the author: At present the ofnode interface is somewhat limited, in that it cannot access the device tree provided by the OS, only the one used by U-Boot itself (assuming these are separate). This prevents using ofnode functions to handle device tree fixups, i.e. ft_board_setup() and the like. The ofnode interface was introduced to allow a consistent API to access the device tree, whether a flat tree or a live tree (OF_LIVE) is in use. With the flat tree, adding nodes and properties at the start of the tree (as often happens when writing to the /chosen node) requires copying a lot of data for each operation. With live tree, such operations are quite a bit faster, since there is no memory copying required. This has to be weighed against the required memory allocation with OF_LIVE, as well as the cost of unflattening and flattening the device tree which U-Boot is running. This series enables support for access to multiple device trees with the ofnode interface. This is already available to some extent with OF_LIVE, but some of the ofnode functions need changes to allow the tree to be specified. The mechanism works by using the top 1-4 bits of the device tree offset. The sign bit is not affected, since negative values must be supported. With this implemented, it becomes possible to use the ofnode interface to do device tree fixups. The only current user is the EVT_FT_FIXUP event. This has two main benefits: - ofnode can now be used everywhere, in preference to the libfdt calls - live tree can eventually be used everywhere, with potential speed improvements when larger number of fixups are used This series is only a step along the way. Firstly, while it is possible to access the 'fix-up' tree using OF_LIVE, most of the fixup functions use flat tree directly, rather than the ofnode interface. These need to be updated. Also the tree must be flattened again before it is passed to the OS. This is not currently implemented. With OFNODE_MULTI_TREE disabled this has almost no effect on code size: around 4 bytes if EVENT is enabled, 0 if not. With the feature enabled, the increase is around 700 bytes, e.g. on venice2: $ buildman -b ofn2a venice2 -sS --step 0 Summary of 2 commits for 1 boards (1 thread, 64 jobs per thread) 01: image: Drop some other #ifdefs in image-board.c arm: w+ venice2 48: wip arm: (for 1/1 boards) all +668.0 text +668.0 This size increase is not too bad, considering the extra functionality, but is too large to enable everywhere. So for now this features needs to be opt-in only, based on EVENT. -

Add a function to copy properties from one node to another. Signed-off-by: -
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: -
This test can operate in all conditions now. Update the test and comments. Signed-off-by: -
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: -
Move this logic out of the test into separate functions, so we can use it in other tests. Signed-off-by: -
Some ofnode functions can only operate on the default device tree, i.e. U-Boot's control FDT. Add comments to that effect. Fix up the reference to device tree bindings while we are here. Signed-off-by: -
We need to be able to look up phandles in any FDT, not just the control FDT. Use the 'other' FDT to test this, with a helper function which gets this as an oftree that can then we used as needed. Add a few more tests and some comments at the top of the file, to explain what is going on. Signed-off-by: -
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: -
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: -
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: -
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: -
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:
