d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

f6dd3f359c efi_loader: correcty determine total device path length
Device paths may consist of multiple instances. Up to now we have only
considered the size of the first instance. For the services of the
EFI_DEVICE_PATH_UTILITIES_PROTOCOL in most cases the total length of the
device path is relevant.

So let's rename efi_dp_size() to efi_dp_instance_size() and create a new
function efi_dp_size() that calculates the total device path length.

c9a63f44b5 efi_loader: new functions to print loaded image information

f9cfad1a61 efi_loader: Fix network DP with DM_ETH
When CONFIG_DM_ETH is set, we assemble the device path properly with a
full device hierarchy. Our helper function dp_fill() even put the MAC
node itself in it for us.

However, for non-DM compatibility we also have code in that added the
MAC node manually. That code now runs on top of the existing MAC node:

  Handle 0x3db2f6b0
    /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
    /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
    /MacAddr(b8:27:eb:e1:81:47,57)/EndEntire

We obviously don't need the additional node and in fact, grub chokes on
it and fails to match the DP against the ethernet device node. So this
patch moves the additional MAC node into the non-DM code path:

  Handle 0x3db3fde0
    /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
    /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
    /EndEntire

While at it, we also mark the non-DM MAC node as ethernet.

ba718e67a2 efi_loader: Optimize GOP switch
We usually try to compile for size, not for speed. Unfortunately with the
more powerful GOP infrastructure to handle all sorts of GOP operations, we
end up slowing down our copying hot path quite a lot.

So this patch moves the 4 possible GOP operation modes into separate
functions which call a common function again. The end result of that is
more optimized code that can properly do constant propagation throughout
its switch() statements and thus removes compares in the hot path.

'compatible' property of the root node exists. If available it prints the
'serial-number' property.

The serial-number property is derived from the environment variable
'serial#'. This can be used to check if the image_setup_libfdt() function
is executed.

A Python test is supplied. It sets a value for serial# and checks that the
selftest shows this as serial-number.
