Asking if the alias we found actually points at the device tree node
we passed in (in the guise of its offset from blob) can be done simply
by asking if the fdt_path_offset() of the alias' path is identical to
offset.
In fact, the current method suffers from the possibility of false
negatives: dtc does not necessarily emit a phandle property for a node
just because it is referenced in /aliases; it only emits a phandle
property for a node if it is referenced in <angle brackets>
somewhere. So if both the node we passed in and the alias node we're
considering don't have phandles, fdt_get_phandle() returns 0 for both.
Since the proper check is so simple, there's no reason to hide that
behind a config option (and if one really wanted that, it should be
called something else because there's no need to involve phandle in
the check).

Booting from a short-form device path which starts with the first element
being a File Path Media Device Path failed because it doesn't contain
any valid device with simple file system protocol and efi_dp_find_obj()

With this patch applied, all the media devices with simple file system

This new implementation is still a bit incompatible with the UEFI
specification in terms of:
* not creating real boot options
* not try
"If a device does not support the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, but
supports the EFI_BLOCK_IO_PROTOCOL protocol, then the EFI Boot Service
ConnectController must be called for this device with DriverImageHandle

Under the current implementation, booting from removable media using
a architecture-specific default image name, say BOOTAA64.EFI, is
supported only in distro_bootcmd script. See the commit 74522c898b
("efi_loader: Add distro boot script for removable media").
This is, however, half-baked implementation because
1) UEFI specification requires this feature to be implemented as part
of Boot Manager's responsibility:
3 - Boot Manager
3.5.1 Boot via the Simple File Protocol
When booting via the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, the FilePath will
start with a device path that points to the device that implements the
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL or the EFI_BLOCK_IO_PROTOCOL. The next
part of the FilePath may point to the file name, including
subdirectories, which contain the bootable image. If the file name is
a null device path, the file name must be generated from the rules
defined below.
...
3.5.1.1 Removable Media Boot Behavior
To generate a file name when none is present in the FilePath, the
firmware must append a default file name in the form
\EFI\BOOT\BOOT{machine type short-name}.EFI ...
2) So (1) entails the hehavior that the user's preference of boot media
order should be determined by Boot#### and BootOrder variables.
With this patch, the semantics mentioned above is fully implemented.
For example, if you want to boot the system from USB and SCSI in this
order,
* define Boot0001 which contains only a device path to the USB device
(without any file path/name)
* define Boot0002 which contains only a device path to the SCSI device,
and
* set BootOrder to Boot0001:Boot0002
To avoid build error for sandbox, default file name "BOOTSANDBOX.efi"
is defined even if it is out of scope of UEFI specification.

To quote the author:
The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.
It introduces the following concepts:
- bootdev - a device which can hold a distro
- bootmeth - a method to scan a bootdev to find bootflows (owned by
U-Boot)
- bootflow - a description of how to boot (owned by the distro)
This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.
With this we can boot on a Raspberry Pi 3 with just one command:
bootflow scan -lb
which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.
With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.
...
The design is described in these two documents:

This can, however, be problematic particularly in case of file-based

Non-volatile variables are to be restored from EFI system partition
by efi_init_variables() in efi_init_obj_list(). When efi_init_obj_list()
is called in board_init_r(), we don't know yet what disk devices
we have since none of device probing commands (say, scsi rescan) has not
been executed at that stage.
So in this commit, a preparatory change is made; efi_init_obj_list() is
broken into the two functions;
* efi_init_early(), and
* new efi_init_obj_list()
Only efi_init_early() will be called in board_init_r(), which allows
us to execute any of device probing commands, either though "preboot"

is to be invoked at the first execution of an efi-related command

Commit 690af71850 changed this condition
from an explicit
IS_ENABLED(CONFIG_SPL_SEPARATE_BSS)
to
CONFIG_IS_ENABLED(SEPARATE_BSS)
The documentation for CONFIG_IS_ENABLED() in include/linux/kconfig.h
implies that we will get the correct behaviour, but the actual behaviour
differs such that this condition is now always false.
This stopped TPL being able to load the device tree blob at least on the
ROCKPro64 board (RK3399 SoC), since the wrong device tree location was
chosen.
The issues causing this behaviour with CONFIG_IS_ENABLED() are:
1. The documentation implies that CONFIG_SPL_BUILD =>
CONFIG_SPL_<option> is considered before the TPL equivalent.
Actually, the TPL options have higher priority - see definition of
_CONFIG_PREFIX.
2. The documentation implies a fallthrough, eg. if CONFIG_SPL_BUILD is
defined but the CONFIG_SPL_<option> is not, then it will proceed to
check if CONFIG_TPL_BUILD
Actually, if CONFIG_TPL_BUILD is defined, then it stops there
and CONFIG_SPL_BUILD is not considered - see definition of
_CONFIG_PREFIX.
During TPL build, at least for the ROCKPro64, both CONFIG_TPL_BUILD
and CONFIG_SPL_BUILD are defined, but because of the above, only TPL
options are considered. Since there is no CONFIG_TPL_SEPARATE_BSS,
this fails.
