[1/1] arm64: boot: dts: ti: k3-*: Add memory node to bootloader stage commit: 12a29fb4f9a0597ad598f2c986c8e2509a62b6ff All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. [1] https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git -- Vignesh

Add the bootph-all property to the memory node so that it can be accessed by FDT functions at bootloader stage. The bootloader requires the memory node to be able to initialize and set the size of the DRAM banks. For this purpose, make sure all memory nodes are present and standardized, and modify them if not.
