Add a way for drivers to record the of-platdata index of their emulator,

This function finds a device by its driver_info index. With
of-platdata-inst we do not use driver_info, but instead instantiate
udevice records at build-time.
However the semantics of using the function are the same in each case:
the caller provides an index and gets back a device.
So rename the function to device_get_by_ofplat_idx(), so that it can be
used for both situations. The caller does not really need to worry about
the details.

Signed-off-by: Simon Glass <sjg@chromium.org>
At present all possible files are generated, even if some of them just
have a header and an empty body. It is better to generate only the files
that are needed, so that the two types of build (based on the setting of
OF_PLATDATA_INST) can be mutually exclusive.
This is intended to fix a strange problem sometimes found with CI:
Building current source for 1 boards (1 thread, 40 jobs per thread)
sandbox: + sandbox_spl
+drivers/built-in.o: In function `dm_setup_inst':
+drivers/core/root.c:135: undefined reference to
`_u_boot_list_2_udevice_2_root'
+dts/dt-uclass.o:(.u_boot_list_2_uclass_2_serial+0x10): undefined
reference to `_u_boot_list_2_udevice_2_serial'
...
This likely happens when switching from !OF_PLATDATA_INST to
OF_PLATDATA_INST since running 'make xxx_defconfig" does not currently
cause any change in which files are generated. With !OF_PLATDATA_INST
the dt-device.c file has no declarations and this is assumed to be the
starting state. The error above seems to indicate that, after changing
to OF_PLATDATA_INST, the dt-uclass.c file is regenerated but the
dt-device.c files is not. This does not seem possible from the relevant
Makefile.spl rule:
u-boot-spl-platdata := $(obj)/dts/dt-plat.o $(obj)/dts/dt-uclass.o
$(obj)/dts/dt-device.o
cmd_dtoc = $(DTOC_ARGS) -c $(obj)/dts -C include/generated all
include/generated/dt-structs-gen.h $(u-boot-spl-platdata_c) &: \
$(obj)/$(SPL_BIN).dtb
@[ -d $(obj)/dts ] || mkdir -p $(obj)/dts
$(call if_changed,dtoc)
It seems that this cannot regenerate dt-uclass.c without dt-device.c since
'dtoc all' is used. So here the trail ends for now.
In any case it seems better to generate files that are uses and not bother
with those that serve no purpose. So update dtoc to do this automatically.

- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left

The UEFI spec allows a packed array of UEFI device paths in the
FilePathList[] of an EFI_LOAD_OPTION. The first file path must
describe the loaded image but the rest are OS specific.
Previous patches parse the device path and try to use the second
member of the array as an initrd. So let's modify efidebug slightly
and install the second file described in the command line as the
initrd device path.

Up to now we install EFI_LOAD_FILE2_PROTOCOL to load an initrd
unconditionally. Although we correctly return various EFI exit codes
depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the
kernel loader, only falls back to the cmdline interpreted initrd if the
protocol is not installed.
This creates a problem for EFI installers, since they won't be able to
load their own initrd and continue the installation. It also makes the
feature hard to use, since we can either have a single initrd or we have
to recompile u-boot if the filename changes.
So let's introduce a different logic that will decouple the initrd
path from the config option we currently have.
When defining a UEFI BootXXXX we can use the filepathlist and store
a file path pointing to our initrd. Specifically the EFI spec describes:
"The first element of the array is a device path that describes the device
and location of the Image for this load option. Other device paths may
optionally exist in the FilePathList, but their usage is OSV specific"
When the EFI application is launched through the bootmgr, we'll try to
interpret the extra device path. If that points to a file that exists on
our disk, we'll now install the load_file2 and the efi-stub will be able
to use it.
This opens up another path using U-Boot and defines a new boot flow.
A user will be able to control the kernel/initrd pairs without explicit
cmdline args or GRUB.
