Qi
==
Qi (named by Alan Cox on Openmoko kernel list) is a minimal bootloader that
"breathes life" into Linux. Its goal is to stay close to the minimum needed
to "load" and then "boot" Linux -- no boot menus, additional peripheral init
or private states.
What's wrong with U-Boot, they keep telling people to not reinvent the wheel?
=============================================================================
U-Boot is gradually becoming a simplified knockoff of Linux. After using it a
while, it became clear we were cutting and pasting drivers into U-Boot from
Linux, cutting them down and not having a plan to maintain the U-Boot versions
as the Linux ones were changed.
We decided that we would use full Linux for things that Linux is good at and
only have the bootloader do the device init that is absolutely required before
Linux can be pulled into memory and started. In practice since we had a working
U-Boot implementation it meant cutting that right down to the bone (start.S
mainly for s3c2442) and then building it up from scratch optimized to just do
load and boot.
Samsung - specific boot sequence
================================
Right now Qi supports Samsung "steppingstone" scheme devices, but in fact it's
the same in processors like iMX31 that there is a small area of SRAM that is
prepped with NAND content via ROM on the device. There's nothing that stops Qi
use on processors without steppingstone, although the ATAG stuff assumes we deal
with ARM based processor.
Per-CPU Qi
==========
Qi has a concept of a single bootloader binary created per CPU type. The
different devices that use that CPU are all supported in the same binary. At
runtime after the common init is done, Qi asks each supported device code in
turn if it recognizes the device as being handled by it, the first one to reply
that it knows the device gets to control the rest of the process.
Consequently, there is NO build-time configuration file as found on U-Boot
except a make env var that sets the CPU type being built, eg:
make CPU=s3c6410
Booting Heuristics
==================
Qi has one or more ways to fetch a kernel depending on the device it finds it is
running on, for example on GTA02 it can use NAND and SD card devices. It goes
through these device-specific storage devices in order and tries to boot the
first viable kernel it finds, usually /boot/<uImage-device>.bin for example
/boot/uImage-GTA02.bin.
The default order for GTA02 is: 1st SD primary partition, 2nd primary
partition, 3rd primary partition, NAND kernel partition.
You can disable a rootfs for consideration for boot if you add a file
/boot/noboot-<device>, eg, /boot/noboot-GTA02. This differs from renaming or
deleting the kernel image because updating the kernel package would give you a
working kernel again and allow boot, whereas the noboot indication will remain
until you remove it.
The kernel commandline used is associated with the storage device and partition,
this allows the correct root= line to be arrived at without any work.
If no kernel image can be found, Qi falls back to doing a memory test.
Appending to commandline
========================
You can append to the Qi commandline by creating a file /boot/append-<device>,
eg, /boot/append-GTA02 containing the additional kernel commandline you want.
This means you can affect the boot per-rootfs, but that if you reimage the
rootfs you at the same time define what is appeneded. Because these files are
looked for with the <device> name in them, options can be selected depending on
the device the rootfs is run on.
Initrd support
==============
Initrd or initramfs in separate file is supported to be loaded at given
memory address in addition to kernel image. The ATAGs are issued accordingly.
Interactive UI
==============
Being minimalistic by its nature, Qi has very limited abilities to
interact with a user. On GTA02 the red LED and the vibrator are used
(if the battery is in good condition) to notify user of the following
actions:
The LED is turned on either on:
- Successful partition mount
- Successful kernel pull
- Successful initramfs pull
The LED is turned off and vibrator runs briefly either on:
- Fail of kernel pull
- Fail of initramfs pull
- Fail of mount partition
- Skipping of current boot possibility
The LED is turned off either on:
- Start of the kernel
- Start of the mem test
- Start of the kernel pull
- Start of the initramfs pull
If a user presses the AUX button after successful partition mount and
before start of the kernel pull (that is, while the red LED is on),
this boot possibility is skipped (and GTA02 owners can feel
vibration). If a user holds the POWER button just before start of the
kernel, debugging parameters are added to the kernel command line
and a lot of information is output to the screen.
Functional Differences from U-Boot on GTA02
===========================================
- Backlight and USB is not enabled until Linux starts after a few seconds
- No startup splash screen
- by default there is no boot spew on the LCM
- On GTAxx boots from first uSD ext2 / 3 partition containing
/boot/uImage-<devicename>.bin present, eg, /boot/uImage-GTA02.bin, it checks
first three partitions in turn
- On GTA01 and 02 if nothing is workable on the SD Card, or it is not present,
Qi will try to boot from NAND
- You can disable a partition for boot by creating /boot/noboot-<devicename>,
eg, /boot/noboot-GTA02, it will skip it and check the next partition
- Way faster
- There is no concept of "staying in the bootloader". The bootloader exits to
Linux as fast as possible, that's all it does.

/*
* Image Types
*
* "Standalone Programs" are directly runnable in the environment
* provided by U-Boot; it is expected that (if they behave
* well) you can continue to work in U-Boot after return from
* the Standalone Program.
* "OS Kernel Images" are usually images of some Embedded OS which
* will take over control completely. Usually these programs
* will install their own set of exception handlers, device
* drivers, set up the MMU, etc. - this means, that you cannot
* expect to re-enter U-Boot except by resetting the CPU.
* "RAMDisk Images" are more or less just data blocks, and their
* parameters (address, size) are passed to an OS kernel that is
* being started.
* "Multi-File Images" contain several images, typically an OS
* (Linux) kernel image and one or more data images like
* RAMDisks. This construct is useful for instance when you want
* to boot over the network using BOOTP etc., where the boot
* server provides just a single image file, but you want to get
* for instance an OS kernel and a RAMDisk image.
*
* "Multi-File Images" start with a list of image sizes, each
* image size (in bytes) specified by an "uint32_t" in network
* byte order. This list is terminated by an "(uint32_t)0".
* Immediately after the terminating 0 follow the images, one by
* one, all aligned on "uint32_t" boundaries (size rounded up to
* a multiple of 4 bytes - except for the last file).
*
* "Firmware Images" are binary images containing firmware (like
* U-Boot or FPGA images) which usually will be programmed to
* flash memory.
*
* "Script files" are command sequences that will be executed by
* U-Boot's command interpreter; this feature is especially
* useful when you configure U-Boot to use a real shell (hush)
* as command interpreter (=> Shell Scripts).

* IO port access primitives
* -------------------------
*
* The ARM doesn't have special IO access instructions; all IO is memory
* mapped. Note that these are defined to perform little endian accesses
* only. Their primary purpose is to access PCI and ISA peripherals.
*
* Note that for a big endian machine, this implies that the following
* big endian mode connectivity is in place, as described by numerious
* ARM documents:
*
* PCI: D0-D7 D8-D15 D16-D23 D24-D31
* ARM: D24-D31 D16-D23 D8-D15 D0-D7
*
* The machine specific io.h include defines __io to translate an "IO"
* address to a memory address.
*
* Note that we prevent GCC re-ordering or caching values in expressions
* by introducing sequence points into the in*() definitions. Note that
* __raw_* do not guarantee this behaviour.
*
* The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.
