EFI calls are usually defined as asmlinkage. That means we pass all parameters
to functions via the stack x86_32.
On x86_64 however, we need to also stick to the MS ABI calling conventions,
which the EFIAPI define conveniently handles for us. Most EFI functions were
also marked with EFIAPI, except for the entry call.
So this patch adjusts all entry calls to use EFIAPI instead of the manual
asmlinkage attribute.
While at it, we also change the prototype of the entry point to return
efi_status_t instead of ulong, as this is the correct prototype definition.

v1 -> v2:
- Use efi_status_t in all occurences
We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader
always expects that the bitness of the definitions it uses is identical to
the execution.
The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other
way around, so it allows for different bitness of EFI definitions and U-Boot
environment.
This patch explicitly requests via Kconfig that efi_loader can only be enabled
if the bitness is identical. Because we can run efi_loader on x86_64 without
EFI stub enabled, it also ensures that this case propagates the correct ABI
constraints.

This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices
For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol
The uclass provides the bind, start, and stop entry points for the driver
binding protocol.
In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.
The EFI block driver binds to controllers implementing the block io
protocol.
When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.
The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.
A usage example is as following:
U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.
Now the EFI block driver installs the partitions with the simple file
protocol.
iPXE uses the simple file protocol to load Grub or the Linux Kernel.

When calling efi_dp_find_obj(), we usually want to find the *exact* match
of an object for a given device path. However, I ran into a nasty corner case
where I had the following objects with paths available:
Handle 0x9feffa70
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/EndEntire
Handle 0x9feffb58
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/HD(1,800,32000,2de808cb00000000,1,1)/EndEntire
and was searching for
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/HD(1,800,32000,2de808cb00000000,1,1)/EndEntire
But because our device path search looked for any substring match, it would
return
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]/USB(6,0)/EndEntire
because that path is a full substring of the path we were searching for.
So this patch adapts the device path search logic to always look for exact
matches first. The way we distinguish between those cases is by looking at
whether our caller actually deals with remainders.
As a side effect, the code as is from all I can tell now never does a
substring match anymore, because it always gets called with rem=NULL, so
we always only do exact matches now.

Commit bbf75dd934 ("efi_loader: output load options in helloworld")
introduced a const variable in efi_main() called loaded_image_guid which
got populated from a constant struct.
While you would usually expect a compiler to realize that this variable
should really just be a global pointer to .rodata, gcc disagrees and instead
puts it on the stack. Unfortunately in some implementations of gcc it does
so my calling memcpy() which we do not implement in our hello world
environment.
So let's explicitly move it to a global variable which in turn puts it in
.rodata reliably and gets rid of the memcpy().

to introduce the el torito scheme to all partition table types: Spawn
individual disk objects for each partition on a disk.
Unfortunately, that code ended up creating partitions with offset=0 which meant
that anyone accessing these objects gets data from the raw block device instead
of the partition.
Furthermore, all the el torito logic to spawn devices for partitions was
duplicated. So let's merge the two code paths and give partition disk objects
good offsets to work from, so that payloads can actually make use of them.
