| | | | | | | | | | | | | | Multiple generation of RDU boards from ZII come with slight hardware variation that can be detected and fixed-up correctly based on part number stored in EEPROMs that are accessible via RAVE SP. In order to reduce common boilerplate between various RDU boards introduce a bit of abstraction to allow declaring part-number specific fixup in RDU board code.

| * ARM: rpi: save bootargs from VC FDT to vc.bootargsTomaz Solc2019-03-041-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Solc2019-03-043-19/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * ARM: rpi: switch emmc from sdhost to sdhciTomaz Solc2019-02-191-0/+9
| | | | | | | | | | | | | | | | | | | | 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.

| * | images: pbl: verify CONFIG_BAREBOX_MAX_IMAGE_SIZE is not exceededAhmad Fatoum2019-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For platforms such as the at91, the boot ROM imposes an upper limit on barebox file size. Prior to 5a1a5ed253 ("ARM: images: use piggydata"), BAREBOX_MAX_PBLX_SIZE seems to have been the way to go for limiting the size of the final barebox binary when using the PBL. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initially we depended on DDR controller settings for liteSOM and liteboard. With 33fdc89d4cbd ("dts: update to v5.0-rc1") a `device_type = "memory";` property was added to imx6ul-litesom.dtsi file, which causes "ram0" to be added with 512MB size (value in dtsi) instead of the real 256MB size that is configured in barebox-grinn-liteboard-256mb.img. As a result Linux kernel fails to boot. Lets depend on DDR controller settings, by removing whole `/memory` node from device tree. This makes barebox-grinn-liteboard-256mb.img able to boot Linux kernel once again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on kernel 5.0-rc6 update at91 clk support to match the new PMC bindings. Manually added all changes done in the kernel from 4.9-rc3 to 5.0-rc6. New drivers required was added as seperate commits. This includes dt-compat code required to support at91sam5d3, as this is not yet ported to use the new PMC bindings. clk-programmable saw some extra changes - it had never been bulit. It is used only by at91sama5d2 - and barebox has no board support for this cpu (yet). The CONFIG_SOC symbols is used to select the relevant drivers. CONFIG_SOC_SAM9 selects several drivers, and in the future this can be split to keep the image size down. In the kernel CLK_OF_DECLARE_DRIVER() can be used for a two step init. In barebox this is a simple one step init. It was added to have less differences between the kernel and the barebox versions of the drivers.
