The add_u_boot_and_runtime() function paints with a broad brush,
considering all of the memory from the top of U-Boot stack to
gd->ram_top as EFI_RUNTIME_SERVICES_CODE
This is fine, but we need to make sure we don't add a separate entry for
any ACPI tables in this region (which happens when bloblist is used for
tables). Otherwise the memory map looks strange and we get a test
failure on qemu-x86 (only) for the 'virtual address map' test.

QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot
copies out the SMBIOS tables but points directly to the ACPI ones.
The ACPI tables are not aligned on a 4KB boundary, which means that UPL
cannot use them directly, since it uses a reserved-memory node for the
tables and that it assumed (by EDK2) to be 4KB-aligned.
On x86, QEMU provides the tables in a mapped memory region and U-Boot
makes use of these directly, thus making it difficult to use any common
code.
Adjust the logic to fit within the existing table-generation code. Use a
bloblist always and ensure that the ACPI tables is placed in an aligned
region. Set a size of 8K for QEMU. This does not actually put all the
tables in one place, for QEMU, since it currently adds a pointer to the
tables in QFW.
On ARM, enable bloblist so that SMBIOS tables can be added to the
bloblist.

In reworking the BLK usage in Kconfig, I found there's a few issues with
EFI_LOADER=y and BLK=n. In general, we can easily say that
lib/efi_loader/efi_file.c also should only be built with CONFIG_BLK.
That however leaves the bootmgr code, eficonfig code and then parts of
efi_device_path.c, efi_boottime.c and efi_setup.c which functionally
depend on BLK. While these calls can be if'd out, I'm unsure if the
result is usable. So rather than leave that buildable and imply that it
is, I'm leaving that combination non-buildable and commenting that
EFI_LOADER depends on BLK in the Kconfig currently.

Raymond Mao <raymond.mao@linaro.org> says:
Motivations for changes:
Current SMBIOS library and command-line tool is not fully matching with
the requirements:
1. Missing support for other mandatory types (#7, #9, #16, #17, #19).
2. Only a few platforms support SMBIOS node from the device tree.
3. Values of some fields are hardcoded in the library other than fetching
from the device hardware.
4. Embedded data with dynamic length is not supported (E.g. Contained
Object Handles in Type #2 and Contained Elements in Type #3)
Changes:
1. Refactor the SMBIOS library and command-line tool to better align with
the SMBIOS spec.
2. Create an arch-specific driver for all aarch64-based platforms to fetch
SMBIOS private data from the device hardware (processor and cache).
3. Create a sysinfo driver to poppulate platform SMBIOS private data.
4. Add generic SMBIOS DTS file for arm64 platforms for those common strings
and values which cannot be retrieved from the system registers.
Vendors can create their own SMBIOS node using this as an example.
For those boards without SMBIOS nodes, this DTS file can be included to
have a generic SMBIOS information of the system.
5. Add support for Type #7 (Cache Information) and link its handles to
Type #4.
6. To minimize size-growth for those platforms which have not sufficient
ROM spaces or the platforms which don't need detailed SMBIOS
information, new added fields are only being built when kconfig
GENERATE_SMBIOS_TABLE_VERBOSE is selected.
Once this patch is acceptted, subsequent patch sets will add other missing
types (#9, #16, #17, #19).
Tests:
To test this with QEMU arm64, please follow the guide on dt_qemu.rst to
get a merged DT to run with.
```

Add detailed SMBIOS information as following:
1. Missing fields in Type #3 and #4
2. Type #7
Add support to dynamic length of contained object handles and
elements.
As SMBIOS is a fundamental feature which is enabled for all

information is under kconfig GENERATE_SMBIOS_TABLE_VERBOSE.
Board maintainers can determine whether to select this feature.

Current smbios library does not fully match to the specification.
It hardcodes values instead of exposing values from the device.
It does not reserve the space to support dynamic length for

The refactoring of this patch includes:
1. Expose values from device via sysinfo interface.
2. Replace smbios_add_prop with smbios_add_prop_si to allow getting
string values from sysinfo.
3. Add smbios_get_val_si to get values from sysinfo or device tree.
4. Use sysinfo_get_data to get data area.
5. Reserve the space of contained object handles and elements.
6. Miscellaneous fixes in smbios.

A few changes for the TPM subsystem wrt to EventLong creation and measurements.
Generally speaking it's insecure for a TPM to not cap all the active PCRs
when performing measurements.
Up to now we had code querying the active PCR banks on the fly and reason
whether it should perform a measurement or not. Since a TPM requires a reset
to change the active PCR banks, it's easier and faster to store them in an
array in the device private data and check against that.
This relates to an interesting feature some bootloaders have. For example
TF-A can't extend a PCR since it has no TPM drivers, but can produce an
EventLog that U-Boot can replay on the hardware once that comes up.
The supported hash algorithms of the TF-A generated Eventlog are generated
at compile time. When trying to replay an EventLog the TPM active PCR banks
and the created EventLog algorithms must agree. We used to report an error
but that changed in commit 97707f12fdab ("tpm: Support boot measurements").
This PR also brings up the old behavior and an error is reported now while
printing a human readable list of the mismatched algorithms.

We used to stop replaying an EventLog if parsing failed, but that got
lost in commit 97707f12fdab ("tpm: Support boot measurements").
When an EventLog is passed yo us from a previous bootloader, we want to
validate it as much as we can and make sure the defined PCR banks of
the log exist in our TPM and firmware so we can replay it if needed or
use it as-in, in case the PCRs are already extended.
So let's add the checks back and while at it simplify the logic of
rejecting an EventLog.

Add a bool var into hash_algo_list to indicate whether the algorithm
is supported or not and move the IS_ENABLED to only cover this var.
So that we can have the name, hash, mask and size no matter the
digest kconfigs are enabled or not.
In before, tpm2_algorithm_to_len() and tcg2_algorithm_to_mask() are used to
identify an unsupported algorithm when they return 0.
It is not the case now when hash_algo_list always provides algorithm size
and mask, thus a new API is introduced to check if an algorithm is
supported by U-Boot.

The fix provided by 997fc12ec91 is actually introducing
a buffer overrun, and the overrun is effective if the
memory after the reloc section is not zeroed.
Probably that's why this bug is not always noticeable.
The problem is that 8-bytes 'rel' pointer can be 4-bytes aligned
according to the PE Format, so the actual relocate function can
take values after the reloc section.
One example is the following dump from the reloc section:
bce26000: 3000 0000 000c 0000 0000 0000 0000 0000
bce26010: 7c00 9340 67e0 f900 1c00 0ea1 a400 0f20
This section has two relocations at offset bce26008 and bce2600a,
however the given size (rel_size) for this relocation is 16-bytes
and this is coming form the efi image Misc.VirtualSize, so in this
case the 'reloc' pointer ends at affset bce2600c and is taken as
valid and this is where the overflow is.
In our system we see this problem when we are starting the
Boot Guard efi image.
This patch is fixing the overrun while preserving the fix done
by 997fc12ec91.

free_mem is a misnomer. We never update it with the free memory for
LMB. Instead, it describes all available memory and is checked against
used_mem to decide whether an area is free or not.
So let's rename this field to better match its usage.

lmb_reserve() is just calling lmb_reserve_flags() with LMB_NONE.
There's not much we gain from this abstraction.
So let's remove the latter, add the flags argument to lmb_reserve()
and make the code a bit easier to follow.

LMB flags is not an enum anymore. It's currently used as a bitmask
in various places of our code. So make it a u32 which is more
appropriate when dealing with masks.

We already have a macro for this. Use it instead of adding yet another
variant for alignment.

Fix warnings from kernel-doc script. Improve and unify overall style of
kernel-doc comments in lmb source files. Move all kernel-doc comments
for public functions into the header, as recommended in U-Boot
documentation [1]:
Non-trivial functions should have a comment which describes what
they do. If it is an exported function, put the comment in the
header file so the API is in one place. If it is a static function,
put it in the C file.
This also takes care of existing duplication. While at it, do a bit of
cosmetic cleanups as well.
No functional change.
