* ARM: boards: skov-imx6: make use of of_prepend_machine_compatible()Oleksij Rempel2022-05-051-37/+3
| | | | | | | | | Replace board specific fixup_machine_compatible() with generic of_prepend_machine_compatible() Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Link: https://lore.barebox.org/20220503091220.3871612-5-o.rempel@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: rename of_find_node_by_name() to of_find_node_by_name_address()Sascha Hauer2022-03-081-2/+2
| | | | | | | | | | | | | of_find_node_by_name() has the same name as the corresponding kernel function but a different semantics. A node name is comprised of the nodes name and a unit address, separated with '@'. Linux of_find_node_by_name() matches only the name before the '@' whereas the barebox function compares the full name. As several callers depend on the barebox semantics we can't just change the semantics, so rename the barebox function to of_find_node_by_name_address().

* ARM: i.MX: Add support for Skov i.MX6 boardsJuergen Borleis2021-04-136-0/+1214
The Skov platform potentially consists of many variants of CPUs (i.MX6S/DL and i.MX6D/Q), NAND memories (size differs from 256 MiB to 8 GiB) and populated SDRAM (256 MiB up to 2 GiB). All these variants share one PCB. Some bootstrap resistors are provided which decode the variant and which allow for it's detection at runtime. This information is needed to choose the bootspec entry with the matching devicetree to boot the system. Based upon this mechanism usage of a single Barebox image and Linux root filesystem for all known board variants is made possible.
