[PATCH 0/2] efi_loader: efi_setup: Add efi_start_obj_list() and use it to set PXE IP address

[Adriano Cordova]

The command bootefi calls efi_init_obj_list to do the efi set up
before launching an .efi payload, but efi_init_obj_list is called
only once. There are some initializations which depend on the
environment and should be done each time a payload gets launched and
not only once and can now be done in efi_start_obj_list(). A motivation
for this change is the following order of events:

1. Launch an EFI application (e.g. bootefi hello)
2. Change the ip address
3. Launch another application which uses the pxe protocol

As the EFI pxe protocol was initialized when the handles
for efi net were created in 1., the ip was hardcoded there.

In this example, another possibility would be to make a callback for ip
address changes to go all the way up to efi_net.
