The directory name from an fdtdir directive in a PXE config file should
always be pre-pended to the DTB filename; it shouldn't matter whether
the DTB filename came from the $fdtfile environment variable, or whether
it was constructed dynamically from ${soc}-${board}.dtb. Fix the code to
always prepend the directory name.

pxe.c provides both the "pxe" command which relies on a network, and the
"sysboot" command which doesn't. Fix the file to compile when network
support isn't enabled. This is useful e.g. on the Raspberry Pi which has
no network support yet, but will soon support the sysboot command.

People who write (or scripts that auto-generate) extlinux.conf don't
want to know about HW-specific information such as FDT filenames. Create
a new extlinux.conf tag "fdtdir" that specifies only the directory where
FDT files are located, and defer all knowledge of the filename to U-Boot.
The algorithm implemented is:
==========
if $fdt_addr_r is set:
if "fdt" tag was specified in extlinux.conf:
load the FDT from the filename in the tag
else if "fdtdir" tag was specified in extlinux.conf:
if "fdtfile" is set in the environment:
load the FDT from filename in "$fdtfile"
else:
load the FDT from some automatically generated filename
if no FDT file was loaded, and $fdtaddr is set:
# This indicates an FDT packaged with firmware
use the FDT at $fdtaddr
==========
A small part of an example /boot/extlinux.conf might be:
==========
LABEL primary
LINUX zImage
FDTDIR ./
LABEL failsafe
LINUX bkp/zImage
FDTDIR bkp/
==========
... with /boot/tegra20-seaboard.dtb or /boot/bkp/tegra20-seaboard.dtb
being loaded by the sysboot/pxe code.

The specification for extlinux.conf[1] states that "fdt" is an alias for
"devicetree". To date, U-Boot only implements "fdt". Rectify that.

pxelinux and syslinux differ in their handling of absolute paths in menu
files. A pxelinux path is aways prepended with the bootfile path while
syslinux allows for absolute paths. u-boot was always treating a leading
/ as an absolute path breaking some pxelinux setups. Fix this by adding
a flag to distinguish pxelinux vs. syslinux behavior.

Pass a valid cmdtp into do_tftpb(), do_ext2load(), and do_get_fat(), to
avoid possible crashes due to null pointer dereferencing.
Commit d7884e047d does not go far enough.
There is still at least one call chain that can result in a crash.
The do_tftpb(), do_ext2load(), and do_get_fat() functions expect a valid
cmdtp. Passing in NULL is particularly bad in the do_tftpb() case,
because eventually boot_get_kernel() will be called with a NULL cmdtp:
do_tftpb() -> netboot_common() -> bootm_maybe_autostart() -> do_bootm()
-> do_bootm_states() -> bootm_find_os() -> boot_get_kernel()
Around line 991 in cmd_bootm.c, boot_get_kernel() will dereference the
null pointer, and the board will crash.

When we call do_bootm() with a vmlinuz, this would lead to a NULL
pointer dereference, and after talking with Wolfgang the right thing to
do here for now is to make sure that we pass cmdtp to these functions
rather than NULL.

A pxelinux server setup for "default" menu is typically an x86 binary.
This does not work well with a mixed architecture setup. Extend the default

The prompt flag is for displaying a "boot:" prompt in pxelinux. This
doesn't make sense for u-boot as we don't support the pxelinux command
interface. So we should just ignore prompt statements and always show the
menu if a menu is present.

Add support for value of -1 For localboot. A value of -1 means return to
u-boot prompt.
The localboot value is often 0, so we need to distinguish the value from
localboot being selected. A value of greater than or equal to 0 means
attempt local boot command.
If localboot is selected, we don't want to try other entries.

Now DT support is becoming common for all new SoC's. Hence it is better
to have option for getting specific FDT from the remote server.
This patch adds support for new label i.e. 'fdt'. This will allow to
retrieve 'fdt blob' from the remote server. This patch take care for
the following scenarios.
The usage of fdt is optional.
The 'fdt blob' can be retrieved from tftp or can be available locally
or can be absent.
If 'fdt_addr_r' environment variable is set and 'fdt' label is defined
retrieve 'fdt blob' from tftp. 'fdt_addr_r' is then passed along bootm
command.
If 'fdt_addr' is set and 'fdt blob' is not retrieved from the tftp pass
'fdt_addr' to bootm command. In this case 'fdt blob' will be available
at 'fdt_addr'.
If 'fdt_addr' is not set and 'fdt blob' is not retrieve from tftp pass
NULL to boot command. In this case 'fdt blob' is not required and absent.
