* of: Fix reproducible names for #address-cells != 1Sascha Hauer2019-03-181-2/+2
| | | | | | | | | | | | | | For the new "fixed-partitions" binding we ignore the partitions subnode for creating reproducible names and set node to its parent. To get the number of address cells we must call of_n_addr_cells() before setting node to its parent though, not afterwards. With the current behaviour we always get OF_ROOT_NODE_ADDR_CELLS_DEFAULT (=1). This happens to work then the partitioned device is less than 4GiB in size. On bigger devices #address-cells = <2> is chosen by the mtd partition fixup code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Bastian Krause <bst@pengutronix.de>
* Revert "fix zbarebox linking with new ld"Sascha Hauer2019-03-181-1/+1
| | | | | | | | | --no-dynamic-linker is already added just a few lines below, do not add the option twice. This option also needs to be embedded in a test if the linker supports this option which we already have in the other place adding this option. This reverts commit 25de30638a2859f9e07c61821cdc71906b7169b8.

| | | | | | | | | Commit 45f38c1a846f ("ARM: Makefile: Drop unnecessary imxcfg-y settings") dropped the imximg generation for the kindle3.

* mci: imx-esdhc: resolve conflicting flagsAlexander Kurz2019-03-181-4/+5
| | | | | | | | | | | With commit 3354adee3920 ("mci: imx-esdhc: Add bigendian register access support") and commit 15b64fd520c2 ("mci: imx-esdhc: Add layerscape support") two ESDHC_FLAGs got assigned to already existing values. This conflict made the imx6sl usdhc appear to be big endian. Resolve this conflict by assign the new flags to the next vacant values.

| * | ARM: rpi: save bootargs from VC FDT to vc.bootargsTomaz Solc2019-03-042-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting a Raspberry Pi, it is useful to extract bootargs from the device tree that was created by the VideoCore firmware. These bootargs contain for example settings for the framebuffer that the kernel needs to properly set the video output. This commit extracts the bootargs in the board initialization code and saves them to the vc.bootargs global variable. For example, a bootloader environment can then add the contents of this variable to linux.bootargs.vc, which then gets included into the final bootargs for the kernel using CONFIG_FLEXIBLE_BOOTARGS.

| * | ARM: rpi: save fdt that was passed from VideoCoreTomaz Solc2019-03-044-19/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Raspberry Pi, VideoCore firmware creates a device tree that contains information about peripherals that were initialized by VideoCore based on settings in config.txt. Normally this device tree is passed to the Linux kernel via a pointer in the r2 register. A bootloader needs to pass this device tree to the kernel, or some peripherals will not work correctly. Since the VideoCore device tree is not compatible with barebox, we can't just pass it to barebox_arm_entry() as the internal barebox device tree. This commit makes the prebootloader code copy the device tree from VideoCore into a scrap RAM area just above the area reserved for the bootloader. Board initialization code in the bootloader proper then copies it into a file /vc.dtb. The bootloader environment is then free to pass this file to the kernel at boot (e.g. via bootm -o).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pinctrl driver needs to be initialized before mci driver on Raspberry Pi. Otherwise the pinctrl device tree properties in the mci node are ignored. pinctrl is initialized by coredevice_initcall(), so moving mci-bcm2835 to device_initcall() ensures that it is initialized later. There is no reason for mci-bcm2835 to use coredevice_initcall(). Other mci drivers already use device_initcall(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BCM2837 has two mmc interfaces: sdhost and sdhci. On Raspberry Pi 3, sdhost is normally used for SD card/MMC flash and sdhci for the wireless interface. Barebox currently only has a driver for sdhci, so we disable the sdhost interface and remap the pins so that the sdhci has access to the SD card/MMC flash.

With pblx removed, this variable is of no use, so have the existing BAREBOX_MAX_IMAGE_SIZE replace its functionality. Currently BAREBOX_MAX_IMAGE_SIZE is only checked against in the non-PBL case, so add a check in the PBL case as well.
