The Bootloader Specification describes a way how kernels can
be installed on devices and how they can be started by the bootloader.
The bootloader spec is currently supported by (x86) gummiboot and
by systemd which provides a kernel-install script. With the bootloader
spec it's possible for the Operating system to install a new kernel
without knowing about the bootloader and for the bootloader it's possible
to discover and start Operating Systems on a media without being
configured.
For more details about the spec see:
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/
This patch adds barebox support for the spec. It enhances the 'boot'
command so that not only boot script names can be given, but also
devices containing bootloader spec entries. With this it's possible
to call the 'boot' command like: 'boot sd emmc net'. It would then
first look for bootloader spec entries on the (removable) sd card,
then, is nothing is found, on the internal emmc and if still
unsuccessful would call the 'net' bootscript.
The bootloader Spec currently doesn't specify which entry should be
default if multiple entries are found on a single device. Therefore
barebox currently has two extensions of the spec. The $BOOT diretory
can contain a file named 'default'. If present, the content of the
file is treated as a filename under $BOOT/loader/entries/ which is
used as default. Similarly if a file named 'once' is present, the
entry is started once and the file is removed afterwards. This is
useful for testing if a newly installed kernel works before making
it the default.
As on ARM and other Architectures a devicetree has to be specified
for the kernel, the 'devicetree' property is used to specify a
devicetree. Like 'kernel' and 'initrd' this also contains a pth
relative to $BOOT.

Often small files are used to store the value od a variable. This
adds a function to easily read such a variable.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
This introduces some new environment variable helpers and updates
the existing ones. Newly introduced are:
getenv_bool: read a bool variable
getenv_ul: read an unsigned long variable
getenev_uint: read an unsigned int variable
getenv_nonempty: like normal getenv, but does return NULL instead of an
empty string
All new helpers take a pointer to the value. This value is only modified
when the variable exists. This allows the following programming scheme:
unsigned int myvalue = sanedefault;
getenv_uint("myvalue", &myvalue);
So without checking the return value myvalue contains the best possible
value.
getenv_ull is updated to this scheme.

Configuration has the general form of devices with a regular compatible
property. This allows to later add additional drivers or drivers with
different behaviour (for example to add support for redundant environment).
The configuration is all in the /chosen/barebox/ hierarchy of the
devicetree. This separates the configuration from the hardware
description. Also it makes it possible to store the configuration

user of it in barebox is passing anything else than the root node.
Therefore, we rename current function to of_find_node_by_path_from and
introduce a Linux OF API compatible of_find_node_by_path that always
passes the current root_node. Also, all current users of that function
are updated to reflect the API change.

Barebox compares compatible, node names, and property names with strcmp.
Linux by default compares compatible and node names with strcasecmp. To
avoid inconsitencies between Barebox and Linux dts files, we convert to
these default string compare functions.

The tran_speed field as decoded from csd is valid in most cases,
so use it to determine the maximum clock we can support. It is
not valid though for MMC highspeed cards, in this case the
csd contains invalid values and we have to set tran_speed explicitly
to the maximum speed. As the values passed into mci_set_clock are
now based on tran_speed we no longer have to limit the rate to
tran_speed in mci_set_clock.
The (intended) effect of this patch is that highspeed MMC cards are
no longer limited to non highspeed rates.

when the parent clocks are enabled. This exposes the already present

Linux normally has no idea how to retrieve MAC Addresses, but instead
expects the MAC address in the devicetree. This patch adds the MAC
address to the devicetree for Linux if we find a valid one in barebox.
This mechanism is limited of course to devices barebox has a driver for
and which are probed themselves from the devicetree.

We often encounter the situation where slow devices should not be
probed during startup since probing is slow and maybe unnecessary
for unused devices. With MMC we have the 'probe' device parameter,
for ata we have the same, for USB we have the 'usb' command. Overall
this is not very consistent.
With MMC there is the additional problem that the probe parameter
is attached to the logical device when we often have the information
which physical device we want to probe.
This patch adds a 'detect' callback for devices and adds a command
to detect devices and to list the devices which are actually detecable.

Some MMC cards support boot partitions. These are special regions
on the MMC card intended to put a bootloader on.
This patch adds support for these partitions, they are accessible
as /dev/diskx.boot[0|1].
Additionally the partitions can be configured bootable using a
device parameter. This can be used to mark the user area or one
of the boot partitions as bootable.
Since this feature is mostly seen on eMMC cards it is made optional
to lower the size impact for boards which do not have eMMC.

We already have a possibility to register a MAC address provider
based on a ethernet device id. This adds a similar functionality
for devices probed from devicetree. Code can register itself to
be a MAC address provider for a certain devicetree node.
This helps on i.MX to let the IIM unit provide a MAC address for
the FEC.

This patch separates out the "generic" memory
segment registration function (of_add_memory_bank())
from of_add_memory().
The MIPS architecture has different view on memory
resources than the ARM and PPC architectures
so the "generic" of_add_memory_bank() is
unusable for the MIPS architecture.
We can add MIPS-specific of_add_memory_bank()
into arch/mips code.

This is a massively stripped down pinctrl support. The upper API
consists of only of:
int pinctrl_select_state(struct device_d *dev, const char *state);
This is used to setup the pinmux for a device to a certain state.
This function normally does not need to be called manually. The
device core will setup the default state before probing a device.
The pinctrl core has the job of handling the devicetree. It parses
the pinctrl phandles for a device from devicetree, finds the correct
pinctrl device and calls its set_state callback with the pinctrl
setup device node.
The simplicity of this pinctrl framework comes from the fact that
we:
- Limit usage to devicetree only for now. For non devicetree use the
old legacy SoC specific APIs still can be used.
- Do not parse the devicetree into internal data structures which
are used by the drivers later. This adds the overhead that we
may parse the devicetree multiple times for more dynamic setups,
but on the other hand we do not need to parse devices from the
devicetree we don't use in barebox
- Do not detect resource conflicts. Since the framework mainly is
a devicetree parser this would be hard to implement. It should
be easy for board maintainers to avoid resource conflicts though.
