The GPIO list is very long in many cases and most of them are not used.
By default, show only the GPIOs that are in use, and provide a flag to show
all of them. This makes the 'gpio status' command much more pleasant.
In order to do this, driver model now exposes a method for obtaining the
'function' of a GPIO, which describes whether it is an input or output, for
example. Implementation of this method is optional.

The default format for arm64 Linux kernels is the "Image" format,
described in Documentation/arm64/booting.txt. This, along with an
optional gzip compression on top is all that is generated by default.
The Image format has a magic number within the header for verification,
a text_offset where the Image must be run from, an image_size that
includes the BSS and reserved fields.
This does not support automatic detection of a gzip compressed image.

One specific USB 3.0 device behaves strangely when reset by
usb_new_device()'s call to hub_port_reset(). For some reason, the device
appears to briefly drop off the bus when this second bus reset is
executed, yet if we retry this loop, it'll eventually come back after
another two resets.
If USB bus reset is executed over and over within usb_new_device()'s call
to hub_port_reset(), I see the following sequence of results, which
repeats as long as you want:
1) STAT_C_CONNECTION = 1 STAT_CONNECTION = 0 USB_PORT_STAT_ENABLE 0
2) STAT_C_CONNECTION = 1 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0
3) STAT_C_CONNECTION = 1 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 1
The device in question is a SanDisk Ultra USB 3.0 16GB memory stick with
USB VID/PID 0x0781/0x5581.
In order to allow this device to work with U-Boot, ignore the
{C_,}CONNECTION bits in the status/change registers, and only use the
ENABLE bit to determine if the reset was successful.
To be honest, extensive investigation has failed to determine why this
problem occurs. I'd love to know! I don't know if it's caused by:
* A HW bug in the device
* A HW bug in the Tegra USB controller
* A SW bug in the U-Boot Tegra USB driver
* A SW bug in the U-Boot USB core
This issue only occurs when the device's USB3 pins are attached to the
host; if only the USB2 pins are connected the issue does not occur. The
USB3 controller on Tegra is in reset, so is not actively communicating
with the device at all - a USB3 analyzer confirms this. Slightly
unplugging the device (so the USB3 pins don't contact) or using a USB2
cable or hub as an intermediary avoids the problem. For some reason,
the Linux kernel (either on the same Tegra board, or on an x86 host)
has no issue with the device, and I observe no disconnections during
reset.
This change won't affect any USB device that already works, since such
devices could not currently be triggering the error return this patch
removes, or they wouldn't be working currently.
However, this patch is quite reliable in practice, hence I hope it's
acceptable to solve the problem.
The only potential fallout I can see from this patch is:
* A broken device that triggers C_CONNECTION/!CONNECTION now causes the
loop in hub_port_reset() to run multiple times. If it never succeeds,
this will cause "usb start" to take roughly 1s extra to execute.
* If the user unplugs a device while hub_port_reset() is executing, and
very quickly swaps in a new device, hub_port_reset() might succeed on
the new device. This would mean that any information cached about the
original device (from the descriptor read in usb_new_device(), which
simply caches the max packet size) might be invalid, which would cause
problems talking to the new device. However, without this change, the
new device wouldn't work anyway, so this is probably not much of a
loss.

When "pxe boot" downloads the initrd/kernel/DTB, netboot_common() saves
the downloaded filename to global variable BootFile. If the boot
operation is aborted, this global state is not cleared. If "dhcp" is
executed later without any arguments, BootFile is not cleared, and when
the DHCP response is received, BootpCopyNetParams() writes the value into
environment variable bootfile.
This causes the following scenario:
* Boot script executes dhcp; pxe get; pxe boot
* User CTRL-C's the PXE menu, which causes the first menu item to be
booted, which causes some file to be downloaded.
(This boot-on-CTRL-C behaviour is arguably a bug too, but it's a
separate bug and the bug this patch fixes would still exist if the user
simply waited to press CTRL-C until "pxe boot" started downloading
files)
* User CTRL-C's the file downloads, but the filename is still written to
the bootfile environment variable.
* User re-runs the boot command, which in my case executes "dhcp; pxe get;
pxe boot" again, and "dhcp" picks up the saved bootfile environment
variable and proceeds to download a file that it shouldn't.
To solve this, modify the implementation of "pxe get" to clear BootFile
if the whole boot operation fails, which avoids this whole mess.
An alternative would be to modify netboot_common() such that the no-
arguments case explicitly clears the global variable BootFile. However,
that would prevent the following command sequences from working:
$ dhcp filename # downloads "filename"
$ dhcp # downloads $bootfile, i.e. "filename"
or:
$ setenv bootfile filename
$ dhcp # downloads $bootfile, i.e. "filename"
... and I assume someone relies on U-Boot working that way.

Devices are not all identified by a single integer. To support
this, defer the parsing of the device string to the IO backed, so that
it can apply the appropriate rules.
SPI devices are specified as controller:chip_select. SPI/SF support will

MMC devices can also be specified as controller[.hwpart][:partition] in
many commands, although we don't support that syntax in DFU.

These commands may be used to determine the size of a file without
actually reading the whole file content into memory. This may be used

For sandbox we have a fallback console which is used very early in
U-Boot, before serial drivers are available. Rather than try to guess
when to switch to the real console, add a flag so we can be sure. This
makes sure that sandbox can always output a panic() message, for example,
and avoids silent failure (which is very annoying in sandbox).
Signed-off-by: Simon Glass <sjg@chromium.org>

If the console is not present, we try to reduce overhead by stopping any
output in vprintf(), before it gets to putc(). This is of dubious merit
in general, but in the case of sandbox it is incorrect since we have a
fallback console which reports errors very early in U-Boot. If this is
defeated U-Boot can hang or exit with no indication of what is wrong.
Remove the optimisation for sandbox.

Initialise devices marked 'pre-reloc' and make them available prior to
relocation. Note that this requires pre-reloc malloc() to be available.
Signed-off-by: Simon Glass <sjg@chromium.org>

Driver model currently only operates after relocation is complete. In this
state U-Boot typically has a small amount of memory available. In adding
support for driver model prior to relocation we must try to use as little
memory as possible.
In addition, on some machines the memory has not be inited and/or the CPU
is not running at full speed or the data cache is off. These can reduce
execution performance, so the less initialisation that is done before
relocation the better.
An immediately-obvious improvement is to only initialise drivers which are
actually going to be used before relocation. On many boards the only such
driver is a serial UART, so this provides a very large potential benefit.
Allow drivers to mark themselves as 'pre-reloc' which means that they will
be initialised prior to relocation. This can be done either with a driver
flag or with a 'dm,pre-reloc' device tree property.
To support this, the various dm scanning function now take a 'pre_reloc_only'
parameter which indicates that only drivers marked pre-reloc should be
bound.

At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.
For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.
Instead, add a stdio_dev pointer to each of the stdio member functions.
Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.
Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

If we are to have driver model before relocation we need to support some
way of calling memory allocation routines.
The standard malloc() is pretty complicated:
1. It uses some BSS memory for its state, and BSS is not available before
relocation
2. It supports algorithms for reducing memory fragmentation and improving
performace of free(). Before relocation we could happily just not support
free().
3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since
this has been loaded anyway this is not really a problem.
The simplest way to support pre-relocation malloc() is to reserve an area
of memory and allocate it in increasing blocks as needed. This
implementation does this.
To enable it, you need to define the size of the malloc() pool as described
in the README. It will be located above the pre-relocation stack on
supported architectures.
Note that this implementation is only useful on machines which have some
memory available before dram_init() is called - this includes those that
do no DRAM init (like tegra) and those that do it in SPL (quite a few
boards). Enabling driver model preior to relocation for the rest of the
boards is left for a later exercise.
