d50244e9d8 pxe: Allow calling the pxe_get logic directly
Refactor this code so that we can call the 'pxe get' command without going
through the command-line interpreter. This makes it easier to get the
information we need, without going through environment variables.

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.

fd3fa5c394 pxe: Use a context pointer
At present the PXE functions pass around a pointer to command-table entry
which is very strange. It is only needed in a few places and it is odd to
pass around a data structure from another module in this way.

For bootmethod we will need to provide some context information when
reading files.

Create a PXE context struct to hold the command-table-entry pointer and
pass that around instead. We can then add more things to the context as
needed.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

For this, add "menu background" support in pxe command.

2023000aed cmd: pxe: add support for FIT config selection
Add a way in configuration files (exlinux.conf for sysboot command)
to select a specific FIT configuration. The configuration is selected
with a string added after the FIT filename in the label "KERNEL" or
"LINUX", using the same format than bootm command:

KERNEL [Filename]#<conf>[#<extra-conf[#...]]

This configuration string, beginning by '#', is directly appended
to bootm argument 1 after <kernel_addr_r>.

bootm [<kernel_addr_r>]#<conf>[#<extra-conf[#...]]

see doc/uImage.FIT/command_syntax_extensions.txt for details

Example :
 KERNEL /fit.itb#cfg1
 KERNEL /fit.itb#cfg2

Configuration can be use also for overlay management :
 KERNEL /fit.itb#cfg1#dtbo1#dtbo3

86fbad2492 menu: fix timeout duration
For distro-boot, the TIMEOUT directive in the boot script specifies
how long to pause in units of 1/10 sec. [1]

Commit 8594753ba0 ("menu: only timeout when menu is displayed")
corrected this by simply dividing the timeout value by 10 in
menu_interactive_choice().

I see two problems:

 - For example, "TIMEOUT 5" should wait for 0.5 sec, but the current
   implementation cannot handle the granularity of 1/10 sec.
   In fact, it never breaks because "m->timeout / 10" is zero,
   which means no timeout.

 - The menu API is used not only by cmd/pxe.c but also by
   common/autoboot.c .  For the latter case, the unit of the
   timeout value is _second_ because its default is associated
   with CONFIG_BOOTDELAY.

To fix the first issue, use DIV_ROUND_UP() so that the timeout value
is rounded up to the closest integer.

For the second issue, move the division to the boundary between
cmd/pxe.c and common/menu.c .  This is a more desirable place because
the comment of struct pxe_menu says:

 * timeout - time in tenths of a second to wait for a user key-press before
 *           booting the default label.

Then, the comment of menu_create() says:

 * timeout - A delay in seconds to wait for user input. If 0, timeout is
 * disabled, and the default choice will be returned unless prompt is 1.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

59ee8f83b6 cmd/pxe.c: Rework bootargs construction to clarify string checks
As the code currently stands, we first check that the length of the
given command line, along with ip_str/mac_str along with an additional 1
for the NULL termination will fit within the buffer we have, and if not,
we return an error.  The way this code was originally written however
left Coverity "unhappy" due to using strcat rather than strncat.
Switching this to strncat however causes clang to be unhappy that we
aren't enforcing the "1" portion within strncat.  Rather than further
re-work the code to include a "- 1" in this case as well, make the
strcat code only be done within the else side of the length test.  This
keeps both clang and Coverity happy.

48ee0a87bc cmd/pxe.c: Rework initrd and bootargs handling slightly
For the initrd portion of handling our bootm arguments we do not have a
sufficiently long enough buffer for some improbable 64bit cases.  Expand
this buffer to allow for a 64bit address and almost 256MB initrd to be
used.  Make use of strncpy/strncat when constructing the values here
since we know what the worst case valid values are, length wise.

Similarly for bootargs themselves, we need to make use of strlen/sizeof
and strncpy/strncat to ensure that we don't overflow bootargs itself.
