* ARM: dts: vexpress-v2p-ca15: adapt fixed NOR flash partition setupAhmad Fatoum2020-07-051-10/+13
| | | | | | | | | | | | | | | | | | | | | | Roland already fixed the vexpress-v2p-ca9: > Upstream DTS commit 62a5017bf825c9e4d317 ("ARM: dts: vexpress: specify > AFS partition") [1] introduced an empty node at /smb@4000000 > /motherboard/flash@0,00000000/partitions, which is preferred by the OF > partitions parser over the single partition nodes. In the same commit, > upstream set the compatible to "arm,arm-firmware-suite", which barebox > does not know about. Adapt our fixed partition setup accordingly by > wrapping all partitions in an extra "partitions" node with the correct > compatible. > [1]: https://git.kernel.org/linus/62a5017bf825c9e4d3176eb975a01c329a9f36 Do the same for the vexpress-v2p-ca15. While at it use the new label: added along with 6940ba22c66a ("dts: update to v5.3-rc1"). This way we aren't (build-)broken, when the upstream path changes in v5.8-rc1.

* ARM: dts: align all applicable memory nodes with spec and conventionAhmad Fatoum2020-06-2315-17/+27
| | | | | | | | | | | | | | | | | | | | The spec[1] says that top level memory nodes `shall have device_type = "memory"'. Since 8226f7f9 ("of: base: parse all available memory nodes"), we parse only nodes with device_type = "memory", so we should add the device_type property where ever it's missing. When the nodes were first added, this wasn't an issue because the skeleton.dtsi defined a memory skeleton with correct device_type, but this was removed upstream and imported into barebox along with 1dc748b3 ("dts: update to v5.1-rc1"). Upstream device trees with a memory node were adapted to have device_type = "memory" in-line. This wasn't the case for nodes defined only within barebox. Rectify this now and rename the nodes to feature a unit name as well to be aligned with the upstream trend.

* ARM: rpi: dts: fix MMIO resources clash breaking bootAhmad Fatoum2020-06-184-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rpi3b device tree specifies 1G of RAM in the memory node, but maps the highest 16M of RAM's physical address range for peripheral use. When support for device tree probing was first added for the rpi3b in e8fab18835a1 ("ARM: rpi: switch to DT probe and multi-image build"), it had a memory { } node overriding the kernel node size with 0, so the size is computed later correctly. 1dc748b3b202 ("dts: update to v5.1-rc1") came and renamed the upstream memory { } node to memory@0. So instead of overriding the old, we now created a second dummy along with the broken node. barebox did only parse the dummy, so it continued to limp along. 8226f7f90973 ("of: base: parse all available memory nodes") started considering both nodes and rendered barebox v2020.05.0 unable to start up on the rpi3b because of the conflict between RAM range and peripherals like the bcm2835_mbox caused by parsing the broken memory node. At least one board also was broken for the same reason[1], so a more robust approach is in order. For nodes that lack a phandle, the &{/path} syntax can be used instead. This has the benefit that should the path disappear in future, a compile failure would result.

| * | | mci: define fall-back hw_dev->detect for all MCIsAhmad Fatoum2020-06-031-3/+19
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A barebox environment oftree node may reference its storage by a phandle to a partition node under a MCI node. barebox will then call the device's detect method to detect the card if this hasn't happened before. Out of 17 MCI drivers, 8 host drivers already implement a detect method, which just calls mci_detect_card. Provide a generic implementation that does the same.

| * | | MIPS: correctly work with disabled CONFIG_MMUAntony Pavlov2020-06-082-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some issues with CONFIG_MMU=n in MIPS configuration (e.g. qemu-malta_defconfig): * "Cannot request SDRAM region for stack" error message on start; * empty kseg1_ram0 region in the iomem command output. The patch fixes the problems by forcing KSEG1 memory region usage for CONFIG_MMU=n MIPS configurations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nfs_read_reply() interprets the fields of an incoming packet directly as a field length without checking the boundaries. Clamp the maximum length to the packet length to avoid reading out of bounds. Reported-by: Jai Verma <jai2.verma@outlook.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
