6d2f27c5fd efi_loader: variable: support APPEND_WRITE
If EFI_VARIABLE_APPEND_WRITE is specified in attributes at
efi_set_variable(), specified data will be appended to the variable's
original value. Attributes other than APPEND_WRITE should not be
modified.

With this patch, APPEND_WRITE test in 'variables' selftest will pass.

23ad52fff4 efi_loader: device_path: support Sandbox's "host" devices
Sandbox's "host" devices are currently described as UCLASS_ROOT udevice
with DEV_IF_HOST block device. As the current implementation of
efi_device_path doesn't support such a type, any "host" device
on sandbox cannot be seen as a distinct object.

For example,
  => host bind 0 /foo/disk.img

  => efi devices
  Scanning disk host0...
  Found 1 disks
  Device           Device Path
  ================ ====================
  0000000015c19970 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)
  0000000015c19d70 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)

  => efi dh
  Handle           Protocols
  ================ ====================
  0000000015c19970 Device Path, Device Path To Text, Device Path Utilities, Unicode Collation 2, HII String, HII Database, HII Config Routing
  0000000015c19ba0 Driver Binding
  0000000015c19c10 Simple Text Output
  0000000015c19c80 Simple Text Input, Simple Text Input Ex
  0000000015c19d70 Block IO, Device Path, Simple File System

As you can see here, efi_root (0x0000000015c19970) and host0 device
(0x0000000015c19d70) have the same representation of device path.

This is not only inconvenient, but also confusing since two different
efi objects are associated with the same device path and
efi_dp_find_obj() will possibly return a wrong result.

Solution:
Each "host" device should be given an additional device path node
of "vendor device path" to make it distinguishable.

83a74ad143 efi_loader: correct reading of directories
EFI_FILE_PROTOCOL.Read() is used both to read files and directories.

When reaching the end of a directory we always have to return buffer size
zero irrespective of the incoming buffer size. (The described scenario for
a Shim quirk cannot arise because every directory has at least '.' and '..'
as entries.)

Even when the buffer_size is too small multiple times we have to keep a
reference to our last read directory entry.

When we return to the start of the directory via SetPosition() we must
remove the reference to a previously kept directory entry.

7e7cc90e33 optee: Make TZDRAM config options contingent on CONFIG_OPTEE
Commit c7b3a7ee53 ("optee: adjust dependencies and default values for
dram") makes the TZDRAM defines for OPTEE show up for all configs as a
side-effect. While not harmful its not what we really want.

This patch makes the following defines contingent on CONFIG_OPTEE=y

CONFIG_OPTEE_TZDRAM_BASE
CONFIG_OPTEE_TZDRAM_SIZE

Rightly, if you don't have CONFIG_OPTEE=y you don't care about the above
two defines.

b225c92fd0 efi_loader: Change return type of efi_add_memory_map()
We currently have some inconsistent use of efi_add_memory_map()
throughout the code. In particular the return value of efi_add_memory_map()
is not interpreted the same way by various users in the codebase.

This patch does the following:

- Changes efi_add_memory_map() to return efi_status_t.
- Adds a method description to efi_add_memory_map().
- Changes efi_add_memory_map() to return EFI_SUCCESS
- Returns non-zero for error in efi_add_memory_map()
- Updates efi_allocate_pages() to new efi_add_memory_map()
- Updates efi_free_pages() to new efi_add_memory_map()
- Updates efi_carve_out_dt_rsv() to new efi_add_memory_map()
- Updates efi_add_runtime_mmio()  to new efi_add_memory_map()

2a51e16bd5 configs: Make USE_TINY_PRINTF depend on SPL||TPL and be default
The USE_TINY_PRINTF symbol only changes things within SPL and TPL
builds, so make it depend on that support.  Next, make it default as
within these cases we should rarely have need of more advanced print
formats outside of the debug context.

To do this, in a few cases we need to correct our Kconfig dependencies
as we had cases of non-SPL targets select'ing this symbol.  Finally, in
the case of a few boards we really do need the full printf
functionality.

f2980ece06 sandbox: Quit when hang() is called
It doesn't make a lot of sense to hang on sandbox when hang() is called,
since the only way out is Ctrl-C. In fact, Ctrl-C does not work if the
terminal is in raw mode, which it will be if the command-line has not been
reached yet. In that case, Ctrl-Z / kill -9 must be used, which is not
very friendly.

Avoid all of this by quiting when hang() is called.

3bad256f5b lib/vsprintf: allow printing upper case GUIDs
In the UEFI context GUIDs are expected to be rendered in upper case.

The patch uses the formerly unused bit 1 of the parameter str_format
of function uuid_bin_to_str() to indicate if we need upper or lower case
output.

Function uuid_string() in vsprint.c is adjusted to correctly set the bit
depending on the print format code.

20562893fa efi_loader: correct device path check
Since commit 226cddbe32 ("efi_loader: check device path in
InstallMultipleProtocolInterfaces") iPXE fails to access the network.

LocateDevicePath() returns EFI_SUCCESS even if a shorter path is found as a
partial match. It returns the remaining path. So to be sure that we found a
complete match we need to check that the remaining path refers to an end
node.

Provide debug output if a device path has already been installed.

Fixes: 226cddbe32 ("efi_loader: check device path in
       InstallMultipleProtocolInterfaces")
