2017-07-11dm: ofnode: rename ofnode_read_prop() to ofnode_get_property()Masahiro Yamada
This function returns the pointer to the value of a node property. The current name ofnode_read_prop() is confusing. Follow the naming of_get_property() from Linux. The return type (const u32 *) is wrong. DT property values can be strings as well as integers. This is why of_get_property/fdt_getprop returns an opaque pointer.

2017-07-11tegra: fdt: Ensure that the console UART is enabledSimon Glass
Many tegra boards have the console UART node disabled. With livetree this prevents serial from working since it does not 'force' the console to be bound. Updates the affected boards to fix this error. The boards were checked with: for b in $(grep tegra boards.cfg |grep -v integrator | \ awk '{print $7}' | sort); do echo $b; fdtgrep -c nvidia,tegra20-uart b/$b/u-boot.dtb |grep okay; done Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Tested-on: Beaver, Jetson-TK1

2017-07-11dm: core: Add functions to obtain node's address/size cellsSimon Glass
The of_n_addr_cells() and of_n_size_cells() functions are useful for getting the size of addresses in a node, but in a few places U-Boot needs to obtain the actual property value for a node without walking up the stack.

2017-07-11moveconfig: Allow automatic location and adding of 'imply'Simon Glass
By using a Kconfig parser we can find the location of each option in the Kconfig tree. Using the information from the database we can then automatically add an 'imply' option into the right place if requested by the user. Add a -a option to support adding 'imply' options. Display the location of any existing 'imply' option so that progress can be examined. Add a -A option to hide any existing 'imply' options so that already-completed additions need not be considered further. Also add documentation for this feature.

2017-07-11moveconfig: Allow control of which implying configs are shownSimon Glass
Sometimes it is useful to display CONFIG_TARGET or CONFIG_CMD configs. Add an option to control this. Also we generally ignore implying configs which affect fewer than 5 boards. But sometimes it is useful to show those those, so add an option that reduces the minimum to two. ERRATUM configs are never useful for implying things, so ignore those. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-07-11moveconfig: Allow piping in 'git show --stat' outputSimon Glass
It is useful to be able to process only a subset of boards to save time. Often that subset is defined by the defconfig files in a git commit. This change allows things like: # Build the database ./tools.moveconfig.py -b # Find some implying configs ./tools/moveconfig.py -i CONFIG_X # Add some 'imply' statements to Kconfig files ./tools/moveconfig.py -i CONFIG_X -a CONFIG_A,CONFIG_B # Reprocess the defconfig files to see if we can drop some changes git show --stat | ./tools/moveconfig.py -s -d - # Update the commit, with fewer defconfig changes gii commit -au Where the commit contains defconfig files, this will reprocess them to take account of the imply statements that you added.

Some AHCI drivers use SCSI under the hood. Rather than making the AHCI driver be in the SCSI uclass it makes sense to have the AHCI device create a SCSI device as a child. That way we can handle any AHCI-specific operations rather than trying to pretend tha the device is just SCSI. To handle this we need to provide a way for AHCI drivers to bind a SCSI device as its child, and probe it. Add functions for this.
