feb7ac457c dm: core: Add address translation in fdt_get_resource
Today of_address_to_resource() is called only in
ofnode_read_resource() for livetree support and
fdt_get_resource() is called when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required, but the address translation is done
by ofnode_read_resource() caller, for example in
drivers/firmware/scmi/smt.c::scmi_dt_get_smt_buffer() {
...
	ret = ofnode_read_resource(args.node, 0, &resource);
	if (ret)
		return ret;

	faddr = cpu_to_fdt32(resource.start);
	paddr = ofnode_translate_address(args.node, &faddr);
...

The both behavior should be aligned and the address translation
must be called in fdt_get_resource() and removed for each caller.

3627cf4bff efi: Fix ESRT refresh after Capsule update
Indicated by Coverity Scan CID 331147

The ESRT was being refreshed in situations where the UpdateCapsule
procedure failed. In that scenario:

1) the ESRT refresh was superfluous.
2) a failed ESRT refresh return code overwrites the UpdateCapsule error
return code.

This commit ensures that the ESRT is only refreshed when the
UpdateCapsule performs successfully.

6d66502bc7 lmb: Add 2 config to define the max number of regions
Add 2 configs CONFIG_LMB_MEMORY_REGIONS and CONFIG_LMB_RESERVED_REGIONS
to change independently the max number of the regions in lmb
library.

When CONFIG_LMB_USE_MAX_REGIONS=y, move the lmb property arrays to
struct lmb and manage the array size with the element 'max' of struct
lmb_region; their are still allocated in stack.

When CONFIG_LMB_USE_MAX_REGIONS=n, keep the current location in
struct lmb_region to allow compiler optimization.

Increase CONFIG_LMB_RESERVED_REGIONS is useful to avoid lmb errors in
bootm when the number of reserved regions (not adjacent) is reached:
+ 1 region for relocated U-Boot
+ 1 region for initrd
+ 1 region for relocated linux device tree
+ reserved memory regions present in Linux device tree.

The current limit of 8 regions is reached with only 5 reserved regions
in DT.

7d823747c6 efi_loader: esrt: Remove incorrect invocations of EFI_CALL macro
Remove function invocations using the EFI_CALL macro for those
functions that do not have an EFI_ENTRY call in their definition. Such
functions can use u-boot api's which rely on u-boot global data(gd)
pointer. The Arm and RiscV architectures maintain a separate gd
pointer, one for u-boot, and a separate gd for the efi application.

Calling a function through the EFI_CALL macro changes the gd pointer
to that used for the efi application, with u-boot gd being
unavailable. Any function then trying to dereference u-boot's gd will
result in an abort.

Fix this issue by removing the EFI_CALL macro for all of such
functions which do not begin by an EFI_ENTRY function call.

- FMP instance install.

The code ensures that every ESRT entry has a unique fw_class value.

Limitations:
- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left
undefined. Setting these values will require a per-platform function
that returns the image_type/flags as a function of the image fw_class.

53f6a5aa86 efi_loader: Replace config option for initrd loading
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.

134d3387e1 efi_loader: NULL dereference in EFI console
Even if CONFIG_DM_VIDEO=y and stdout="vidconsole", a video device may not
be available. Check the return values of the relevant functions.

If no video output device is available, assume that the serial console is
in use.

6f90899120 efi_selftest: Remove loadfile2 for initrd selftests
We are redefining how u-boot locates the initrd to load via the kernel
LoadFile2 protocol.  This selftest is not relevant any more, so remove
it. A new one will be added later
