a322f54f50 tpm: Change response length of tpm2_get_capability()
For implementing the EFI_TCG2_PROTOCOL we need the count field returned by
the TPM when reading capabilities via tpm2_get_capability().

Adjust the implementation of the 'tpm2 get_capability' command accordingly.

ab02c3fec4 efi_loader: non-volatile variable not deleted from file
When deleting a non-volatile variable it was deleted from memory but the
deletion was not persisted to the file system.

SetVariable() may be called with attributes == 0 to delete a variable. To
determine if the deletion shall be persisted we have to consider the
non-volatile flag in the attributes of the deleted variable and not the
value passed in the call parameter.

d2cb7a22da x86: Allow putting some tables in the bloblist
At present all tables are placed starting at address f0000 in memory, and
can be up to 64KB in size. If the tables are very large, this may not
provide enough space.

Also if the tables point to other tables (such as console log or a ramoops
area) then we must allocate other memory anyway.

The bloblist is a nice place to put these tables since it is contiguous,
which makes it easy to reserve this memory for linux using the 820 tables.

Add an option to put some of the tables in the bloblist. For SMBIOS and
ACPI, create suitable pointers from the f0000 region to the new location
of the tables.

72eda5074b lib: Add getopt
Some commands can get very unweildy if they have too many positional
arguments. Adding options makes them easier to read, remember, and
understand.

This implementation of getopt has been taken from barebox, which has had
option support for quite a while. I have made a few modifications to their
version, such as the removal of opterr in favor of a separate getopt_silent
function. In addition, I have moved all global variables into struct
getopt_context.

The getopt from barebox also re-orders the arguments passed to it so that
non-options are placed last. This allows users to specify options anywhere.
For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as
getopt parsed the options. However, this feature conflicts with the const
argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure
that argv[] argument pointers are not modified."). The reason stated in
that commit is that hush requires argv to stay unmodified. Has this
situation changed? Barebox also uses hush, and does not have this problem.
Perhaps we could use their fix?

I have assigned maintenance of getopt to Simon Glass, as it is currently
only used by the log command. I would also be fine maintaining it.

529441ca89 efi_loader: Disable devices before handing over control
U-Boot Driver Model is supposed to remove devices with either
DM_REMOVE_ACTIVE_DMA or DM_REMOVE_OS_PREPARE flags set, before exiting.
Our bootm command does that by explicitly calling calling
"dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);" and we also disable any
USB devices.

The EFI equivalent is doing none of those at the moment. As a result
probing an fTPM driver now renders it unusable in Linux. During our
(*probe) callback we open a session with OP-TEE, which is supposed to
close with our (*remove) callback. Since the (*remove) is never called,
once we boot into Linux and try to probe the device again we are getting
a busy error response. Moreover all uclass (*preremove) functions won't
run.

So let's fix this by mimicking what bootm does and disconnect devices
when efi_exit_boot_services() is called.

42f804fbba efi_loader: fix use after free in receive path
With DM enabled the ethernet code will receive a packet, call
the push method that's set by the EFI network implementation
and then free the packet.  Unfortunately the push methods only
sets a flag that the packet needs to be handled, but the code
that provides the packet to an EFI application runs after the
packet has already been freed.

To rectify this issue, adjust the push method to accept the packet
and store it in a temporary buffer.  The EFI application then gets
the data copied from that buffer.  This way the packet is cached
until is is needed.

The DM Ethernet stack tries to receive 32 packets at once, thus
we better allocate as many buffers as the stack.

4b2be78ab6 time: Fix get_ticks being non-monotonic
get_ticks does not always succeed. Sometimes it can be called before the
timer has been initialized. If it does, it returns a negative errno.
This causes the timer to appear non-monotonic, because the value will
become much smaller after the timer is initialized.

No users of get_ticks which I checked handle errors of this kind. Further,
functions like tick_to_time mangle the result of get_ticks, making it very
unlikely that one could check for an error without suggesting a patch such
as this one.

This patch panics if we ever get an error. There are two cases in which
this can occur. The first is if we couldn't find/probe the timer for some
reason. One reason for this is if the timer is not available so early. This
likely indicates misconfiguration. Another reason is that the timer has an
invalid/missing device tree binding. In this case, panicing is also
correct. The second case covers errors calling get_count. This can only
occur if the timer is missing a get_count function (or on RISC-V, but that
should be fixed soon).

3f8808ebaa rsa: fix retrieving public exponent on big-endian systems
Commit fdf0819afb (rsa: fix alignment issue when getting public
exponent) changed the logic to avoid doing an 8-byte access to a
possibly-not-8-byte-aligned address.

However, using rsa_convert_big_endian is wrong: That function converts
an array of big-endian (32-bit) words with the most significant word
first (aka a BE byte array) to an array of cpu-endian words with the
least significant word first. While the exponent is indeed _stored_ as
a big-endian 64-bit word (two BE words with MSW first), we want to
extract it as a cpu-endian 64 bit word. On a little-endian host,
swapping the words and byte-swapping each 32-bit word works, because
that's the same as byte-swapping the whole 64 bit word. But on a
big-endian host, the fdt32_to_cpu are no-ops, but
rsa_convert_big_endian() still does the word-swapping, breaking
verified boot.

To fix that, while still ensuring we don't do unaligned accesses, add
a little helper that first memcpy's the bytes to a local fdt64_t, then
applies fdt64_to_cpu(). [The name is chosen based on the
[bl]eXX_to_cpup in linux/byteorder/generic.h].

167fb1f8dc lib: rsa: check algo match in rsa_verify_with_keynode
The algo name should match between the FIT's signature node and the
U-Boot's control FDT.

If we do not check it, U-Boot's control FDT can expect sha512 hash but
nothing will prevent to accept image with sha1 hash if the signature is correct.

a6982a6f76 fit: cipher: aes: allow to store the IV in the FIT image
Binaries may be encrypted in a FIT image with AES. This
algo needs a key and an IV (Initialization Vector). The
IV is provided in a file (pointer by iv-name-hint in the
ITS file) when building the ITB file.

This commits adds provide an alternative way to manage
the IV. If the property iv-name-hint is not provided in
the ITS file, the tool mkimage will generate an random
IV and store it in the FIT image.

cba487c7fc fdtdec: correct test on return of fdt_node_offset_by_phandle
The result of fdt_node_offset_by_phandle is negative for error,
so this patch corrects the check of this result in
fdtdec_parse_phandle_with_args.

This patch allows to have the same behavior with or without OF_LIVE
for the function dev_read_phandle_with_args with cell_name = NULL and
with invalid phandle.

4b71f6dc4e efi_loader: QEMU CONFIG_EFI_GRUB_ARM32_WORKAROUND=n
CONFIG_EFI_GRUB_ARM32 is only needed for architectures with caches that are
not managed via CP15 (or for some outdated buggy versions of GRUB). It
makes more sense to disable the setting per architecture than per defconfig.

Move QEMU's CONFIG_EFI_GRUB_ARM32_WORKAROUND=n from defconfig to Kconfig.
