1a075d4e0d x86: pxeboot: bugfix: Set variable for size of initrd
The problem was, that zboot() didn't work because of missing
ramdisc size.

519e6641db cmd: pxe_utils: Limit fdtcontroladdr usage to non-fitImage
Commit d5ba6188df ("cmd: pxe_utils: Check fdtcontroladdr in label_boot")
forces '$fdtcontroladdr' DT address as a third parameter of bootm command
even if the PXE transfer pulls in a fitImage which contains configuration
node with its own DT that is preferrable to be passed to Linux. Limit the
$fdtcontroladdr fallback utilization to non-fitImages, since it is highly
likely a fitImage would come with its own DT, while single-file images do
need a separate DT.

739e8361f3 distro/pxeboot: Handle prompt variable
Regarding the documentation found here:
https://github.com/u-boot/u-boot/blob/master/common/menu.c#L347

If both timeout and prompt is set to 0 the default entry shall
be booted immediately. However the current behaviour is that
the prompt is shown (tested with distroboot) until the user
selects an entry (no timeout).

This change implements a behaviour as documented. It was tested
with distroboot.

a5dacef738 cmd: pxe: support INITRD and FDT selection with FIT
Since the commit d5ba6188df ("cmd: pxe_utils: Check fdtcontroladdr
in label_boot") the FDT or the FDTDIR label is required in extlinux.conf
and the fallback done by bootm command when only the device tree present
in this command parameters is no more performed when FIT is used for
kernel.

When the label FDT or FDTDIR are absent or if the device tree file is
absent, the PXE command in U-Boot uses the default U-Boot device tree
selected by fdtcontroladdr = gd->fdt_blob, it is the "Scenario 3".

With this scenario the bootm FIP fallback is no more possible with
the extlinux.conf when only "kernel" label is present and is a FIP:

  kernel <path>#<conf>[#<extra-conf[#...]]

As the U-Boot FDT is always provided in the third bootm argument,
the device tree found in FIP is not used as fallback, it was done
previously in boot_get_fdt().

This patch adds a new field kernel_label to save the full kernel label.
The FDT bootm parameters use the kernel address (to avoid to load a
second time the same FIP) and the config when this full label is reused
for "fdt" or "initrd" label.

This FIP support in extlinux.conf is restored when the "FDT" label
can be found and select the same FIP (identical file and configuration):

  kernel <path>#<conf>[#<extra-conf[#...]]
  fdt <path>#<conf>[#<extra-conf[#...]]

The patch add also this possibility for initrd.

  initrd <path>#<conf>[#<extra-conf[#...]]

c2969792c4 cmd: pxe_utils: sysboot: add label override support
This will allow consumers to choose a pxe label at runtime instead of
having to prompt the user. One good use-case for this, is choosing
whether or not to apply a dtbo depending on the hardware configuration.
e.g: for TI's AM335x EVM, it would be convenient to apply a particular
dtbo only when the J9 jumper is on PRUSS mode. To achieve this, the
pxe menu should have 2 labels, one with the dtbo and the other without,
then the "pxe_label_override" env variable should point to the label with
the dtbo at runtime only when the jumper is on PRUSS mode.

This change can be used for different use-cases and bring more
flexibilty to consumers who use sysboot/pxe_utils.

if "pxe_label_override" is set but does not exist in the pxe menu,
the code should fallback to the default label if given, and no failure
is returned but rather a warning message.

U-Boot. When using PXE, if no fdt is defined in the menu file, and
there is no fdt at fdt_addr, add fall back on fdtcontroladdr too.

We are developing board support for the Armv8r64 FVP using
config_distro_bootcmd. We are also using OF_BOARD and would like the
PXE boot option to default to the fdt provided by board_fdt_blob_setup.

4d79e884ad pxe: Return the file size from the getfile() function
It is pretty strange that the pxe code uses the 'filesize' environment
variable find the size of a file it has just read.

Partly this is because it uses the command-line interpreter to parse its
request to load the file.

As a first step towards unwinding this, return it directly from the
getfile() function. This makes the code a bit longer, for now, but will be
cleaned up in future patches.

12df842ee3 pxe: Clean up the use of bootfile
The 'bootfile' environment variable is read in the bowels of pxe_util to
provide a directory to which all loaded files are relative.

This is not obvious from the API to PXE and it is strange to make the
caller set an environment variable rather than pass this as a parameter.

The code is also convoluted, which this feature implemented by
get_bootfile_path().

Update the API to improve this. Unfortunately this means that
pxe_setup_ctx() can fail, so add error checking.
