[U-Boot] [PATCH 00/23] efi_loader implement missing functions

[Heinrich Schuchardt]

This patch sequence contains all patches needed to load
iPXE and use it for downloading and executing images
via https or http or to mount iSCSI volumes.

Network speed on an Odroid C2 reached 30 MB/s which should be
enough for most use cases.

I have tested the following iPXE commands successfully
* dhcp
* route
* ntp
* sanhook iSCSI-target
* chain http-target
* kernel http-target
* boot (after calling kernel)
* exit
* reboot

The only adjustment in iPXE was adding file src/config/local/nap.h with
  #undef NAP_EFIX86
  #undef NAP_EFIARM
  #define NAP_NULL
and src/config/local/myscript.ipxe with
  #!ipxe
  shell
before building iPXE with
  make bin-arm64-efi/snp.efi EMBED=config/local/myscript.ipxe

The next task will be to put iXPE binaries on a server
and to create Travis CI test cases.
