All rights reserved. + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +Generic Distro Configuration Concept +==================================== + +Linux distributions are faced with supporting a variety of boot mechanisms, +environments or bootloaders (PC BIOS, EFI, U-Boot, Barebox, ...). This makes +life complicated. Worse, bootloaders such as U-Boot have a configurable set +of features, and each board chooses to enable a different set of features. +Hence, distros typically need to have board-specific knowledge in order to +set up a bootable system. + +This document defines a common set of U-Boot features that are required for +a distro to support the board in a generic fashion. Any board wishing to +allow distros to install and boot in an out-of-the-box fashion should enable +all these features. Linux distros can then create a single set of boot +support/install logic that targets these features. This will allow distros +to install on many boards without the need for board-specific logic. + +In fact, some of these features can be implemented by any bootloader, thus +decoupling distro install/boot logic from any knowledge of the bootloader. + +This model assumes that boards will load boot configuration files from a +regular storage mechanism (eMMC, SD card, USB Disk, SATA disk, etc.) with +a standard partitioning scheme (MBR, GPT). Boards that cannnot support this +storage model are outside the scope of this document, and may still need +board-specific installer/boot-configuration support in a distro. + +To some extent, this model assumes that a board has a separate boot flash +that contains U-Boot, and that the user has somehow installed U-Boot to this +flash before running the distro installer. Even on boards that do not conform +to this aspect of the model, the extent of the board-specific support in the +distro installer logic would be to install a board-specific U-Boot package to +the boot partition partition during installation. This distro-supplied U-Boot +can still implement the same features as on any other board, and hence the +distro's boot configuration file generation logic can still be board-agnostic. + +Locating Bootable Disks +----------------------- + +Typical desktop/server PCs search all (or a user-defined subset of) attached +storage devices for a bootable partition, then load the bootloader or boot +configuration files from there. A U-Boot board port that enables the features +mentioned in this document will search for boot configuration files in the +same way. + +Thus, distros do not need to manipulate any kind of bootloader-specific +configuration data to indicate which storage device the system should boot +from. + +Distros simply need to install the boot configuration files (see next +section) in an ext2/3/4 or FAT partition, mark the partition bootable (via +the MBR bootable flag, or GPT legacy_bios_bootable attribute), and U-Boot (or +any other bootloader) will find those boot files and execute them. This is +conceptually identical to creating a grub2 configuration file on a desktop +PC. + +Note that in the absense of any partition that is explicitly marked bootable, +U-Boot falls back to searching the first valid partition of a disk for boot +configuration files. Other bootloaders are recommended to do the same, since +I believe that partition table bootable flags aren't so commonly used outside +the realm of x86 PCs. + +U-Boot can also search for boot configuration files from a TFTP server. + +Boot Configuration Files +------------------------ + +The standard format for boot configuration files is that of extlinux.conf, as +handled by U-Boot's "syslinux" (disk) or "pxe boot" (network). This is roughly +as specified at: + +http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/ + +... with the exceptions that the BootLoaderSpec document: + +* Prescribes a separate configuration per boot menu option, whereas U-Boot + lumps all options into a single extlinux.conf file. Hence, U-Boot searches + for /extlinux/extlinux.conf then /boot/extlinux/extlinux.conf on disk, or + pxelinux.cfg/default over the network. + +* Does not document the fdtdir option, which automatically selects the DTB to + pass to the kernel. + +One example extlinux.conf generated by the Fedora installer is: + +------------------------------------------------------------ +# extlinux.conf generated by anaconda + +ui menu.c32 + +menu autoboot Welcome to Fedora.

This enables distros to generate a +U-Boot-specific boot.scr script rather than extlinux.conf as the boot +configuration file. While doing so is fully supported, and +<config_distro_defaults.h> exposes enough parameterization to boot.scr to +allow for board-agnostic boot.scr content, this document recommends that +distros generate extlinux.conf rather than boot.scr. extlinux.conf is intended +to work across multiple bootloaders, whereas boot.scr will only work with +U-Boot. TODO: document the contract between U-Boot and boot.scr re: which +environment variables a generic boot.scr may rely upon. + +The second of those headers sets up the default environment so that $bootcmd +is defined in a way that searches attached disks for boot configuration files, +and executes them if found. + +Required Environment Variables +------------------------------ + +The U-Boot "syslinux" and "pxe boot" commands require a number of environment +variables be set. Default values for these variables are often hard-coded into +CONFIG_EXTRA_ENV_SETTINGS in the board's U-Boot configuration file, so that +the user doesn't have to configure them. + +fdt_addr: + + Mandatory for any system that provides the DTB in HW (e.g. ROM) and wishes + to pass that DTB to Linux, rather than loading a DTB from the boot + filesystem. Prohibited for any other system. + + If specified a DTB to boot the system must be available at the given + address. + +fdt_addr_r: + + Mandatory. The location in RAM where the DTB will be loaded or copied to when + processing the fdtdir/devicetreedir or fdt/devicetree options in + extlinux.conf. + + This is mandatory even when fdt_addr is provided, since extlinux.conf must + always be able to provide a DTB which overrides any copy provided by the HW. + + A size of 1MB for the FDT/DTB seems reasonable. + +ramdisk_addr_r: + + Mandatory. The location in RAM where the initial ramdisk will be loaded to + when processing the initrd option in extlinux.conf. + + It is recommended that this location be highest in RAM out of fdt_addr_, + kernel_addr_r, and ramdisk_addr_r, so that the RAM disk can vary in size + and use any available RAM. + +kernel_addr_r: + + Mandatory. The location in RAM where the kernel will be loaded to when + processing the kernel option in the extlinux.conf. + + The kernel should be located within the first 128M of RAM in order for the + kernel CONFIG_AUTO_ZRELADDR option to work, which is likely enabled on any + distro kernel. Since the kernel will decompress itself to 0x8000 after the + start of RAM, kernel_addr_rshould not overlap that area, or the kernel will + have to copy itself somewhere else first before decompression. + + A size of 16MB for the kernel is likely adequate. + +pxe_addr_r: + + Mandatory. The location in RAM where extlinux.conf will be loaded to prior + to processing. + + A size of 1MB for extlinux.conf is more than adequate. + +scriptaddr: + + Mandatory, if the boot script is boot.scr rather than extlinux.conf. The + location in RAM where boot.scr will be loaded to prior to execution. + + A size of 1MB for extlinux.conf is more than adequate. + +For suggestions on memory locations for ARM systems, you must follow the +guidelines specified in Documentation/arm/Booting in the Linux kernel tree. + +For a commented example of setting these values, please see the definition of +MEM_LAYOUT_ENV_SETTINGS in include/configs/tegra124-common.h. + +Boot Target Configuration +------------------------- + +<config_distro_bootcmd.h> defines $bootcmd and many helper command variables +that automatically search attached disks for boot configuration files and +execute them. Boards must provide configure <config_distro_bootcmd.h> so that +it supports the correct set of possible boot device types. To provide this +configuration, simply define macro BOOT_TARGET_DEVICES prior to including +<config_distro_bootcmd.h>. For example: + +------------------------------------------------------------ +#ifndef CONFIG_SPL_BUILD +#define BOOT_TARGET_DEVICES(func) \ + func(MMC, mmc, 1) \ + func(MMC, mmc, 0) \ + func(USB, usb, 0) \ + func(PXE, pxe, na) \ + func(DHCP, dhcp, na) +#include <config_distro_bootcmd.h> +#endif +------------------------------------------------------------ + +Each entry in the macro defines a single boot device (e.g. a specific eMMC +device or SD card) or type of boot device (e.g. USB disk).

If the board inverts the signal between +the GPIO controller and the device, then the gpio-specifier will represent the +opposite physical level than the signal at the device's pin. + +When the device's signal polarity is configurable, the binding for the +device must either: + +a) Define a single static polarity for the signal, with the expectation that +any software using that binding would statically program the device to use +that signal polarity. + +The static choice of polarity may be either: + +a1) (Preferred) Dictated by a binding-specific DT property. + +or: + +a2) Defined statically by the DT binding itself. + +In particular, the polarity cannot be derived from the gpio-specifier, since +that would prevent the DT from separately representing the two orthogonal +concepts of configurable signal polarity in the device, and possible board- +level signal inversion. + +or: + +b) Pick a single option for device signal polarity, and document this choice +in the binding. The gpio-specifier should represent the polarity of the signal +(at the GPIO controller) assuming that the device is configured for this +particular signal polarity choice. If software chooses to program the device +to generate or receive a signal of the opposite polarity, software will be +responsible for correctly interpreting (inverting) the GPIO signal at the GPIO +controller. + +2) gpio-controller nodes +------------------------ + +Every GPIO controller node must contain both an empty "gpio-controller" +property, and a #gpio-cells integer property, which indicates the number of +cells in a gpio-specifier. + +Example of two SOC GPIO banks defined as gpio-controller nodes: + + qe_pio_a: gpio-controller@1400 { + compatible = "fsl,qe-pario-bank-a", "fsl,qe-pario-bank"; + reg = <0x1400 0x18>; + gpio-controller; + #gpio-cells = <2>; + }; + + qe_pio_e: gpio-controller@1460 { + compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank"; + reg = <0x1460 0x18>; + gpio-controller; + #gpio-cells = <2>; + }; + +2.1) gpio- and pin-controller interaction +----------------------------------------- + +Some or all of the GPIOs provided by a GPIO controller may be routed to pins +on the package via a pin controller. This allows muxing those pins between +GPIO and other functions. + +It is useful to represent which GPIOs correspond to which pins on which pin +controllers. The gpio-ranges property described below represents this, and +contains information structures as follows: + + gpio-range-list ::= <single-gpio-range> [gpio-range-list] + single-gpio-range ::= <numeric-gpio-range> | <named-gpio-range> + numeric-gpio-range ::= + <pinctrl-phandle> <gpio-base> <pinctrl-base> <count> + named-gpio-range ::= <pinctrl-phandle> <gpio-base> '<0 0>' + gpio-phandle : phandle to pin controller node. + gpio-base : Base GPIO ID in the GPIO controller + pinctrl-base : Base pinctrl pin ID in the pin controller + count : The number of GPIOs/pins in this range + +The "pin controller node" mentioned above must conform to the bindings +described in ../pinctrl/pinctrl-bindings.txt. + +In case named gpio ranges are used (ranges with both <pinctrl-base> and +<count> set to 0), the property gpio-ranges-group-names contains one string +for every single-gpio-range in gpio-ranges: + gpiorange-names-list ::= <gpiorange-name> [gpiorange-names-list] + gpiorange-name : Name of the pingroup associated to the GPIO range in + the respective pin controller. + +Elements of gpiorange-names-list corresponding to numeric ranges contain +the empty string. Elements of gpiorange-names-list corresponding to named +ranges contain the name of a pin group defined in the respective pin +controller. The number of pins/GPIOs in the range is the number of pins in +that pin group. + +Previous versions of this binding required all pin controller nodes that +were referenced by any gpio-ranges property to contain a property named +#gpio-range-cells with value <3>.
