binman: Support an assumed size for missing binaries
Binman has a the useful feature of handling missing external blobs
gracefully, including allowing them to be missing, deciding whether the
resulting image is functional or not and faking blobs when this is
necessary for particular tools (e.g. mkimage).
This feature is widely used in CI. One drawback is that if U-Boot grows
too large to fit along with the required blobs, then this is not
discovered until someone does a 'real' build which includes the blobs.
Add a 'assume-size' property to entries to allow Binman to reserve a
given size for missing external blobs.

sandbox: cleanup linker scripts and sections
commit 6e2228fb052b ("Merge patch series "Clean up arm linker scripts"")
was cleaning up linker scripts for armv7 and v8 in a similar fashion.
Several commits in the past -- e.g
commit d0b5d9da5de2 ("arm: make _end compiler-generated")
was moving symbols to be compiler generated. They were defined as c
variables in its own section to force the compiler emit relative a
reference. However, defining those in the linker script will do the
same thing since [0].
So let's remove the special sections from the linker scripts, the
variable definitions from sections.c, and define them as a symbols.
It's worth noting that the linker was discarding the symbols in the
older binary completely since the symbol definition had an extra _.

tpm: allow the user to select the compiled algorithms
Simon reports that after enabling all algorithms on the TPM some boards
fail since they don't have enough storage to accommodate the ~5KB growth.
The choice of hash algorithms is determined by the platform and the TPM
configuration. Failing to cap a PCR in a bank which the platform left
active is a security vulnerability. It might allow unsealing of secrets
if an attacker can replay a good set of measurements into an unused bank.
If MEASURED_BOOT or EFI_TCG2_PROTOCOL is enabled our Kconfig will enable
all supported hashing algorithms. We still want to allow users to add a
TPM and not enable measured boot via EFI or bootm though and at the same
time, control the compiled algorithms for size reasons.
So let's add a function tpm2_allow_extend() which checks the TPM active
PCRs banks against the one U-Boot was compiled with. We only allow
extending PCRs if the algorithms selected during build match the TPM
configuration.
It's worth noting that this is only added for TPM2.0, since TPM1.2 is
lacking a lot of code at the moment to read the available PCR banks.
We unconditionally enable SHA1 when a TPM is selected, which is the only
hashing algorithm v1.2 supports.

expects entropy to be provided by the bootloader by populating
/chosen/kaslr-seed with a 64-bit value from source of entropy at boot.
If we have DM_RNG enabled populate this value automatically when

that is not yet implemented as DM_RNG. We also skip this if

dt will cause measured boot to fail (although there are many other
places the dt is altered).
As this fdt node is added elsewhere create a library function and

the node if present.
For our automatic injection, we will use the first rng device and
not overwrite if already present with a non-zero value (which may
have been populated by an earlier boot stage). This way if a board
specific ft_board_setup() function wants to customize this behavior
it can call fdt_kaslrseed with a rng device index of its choosing and

x86: Set a board-size limit for chromebook_link
Set a size limit for this board so that we get a build error if it grows
too much.
Note that the limit is approximately, since it does not include the FDT,
microcode and fdtmap, which can change in size. However this board is
fairly stable, so overflowing this limit will likely result in the image
not fitting in the ROM space available for U-Boot.

tpm: Avoid code bloat when not using EFI_TCG2_PROTOCOL
It does not make sense to enable all SHA algorithms unless they are
needed. It bloats the code and in this case, causes chromebook_link to
fail to build. That board does use the TPM, but not with measured boot,
nor EFI.
Since EFI_TCG2_PROTOCOL already selects these options, we just need to
add them to MEASURED_BOOT as well.

which makes it hard to see what is going on.

In case when either gpt_verify_headers() or gpt_verify_partitions()

The attempt to free it in those cases in gpt_verify() leads to "use

This is unlikely to cause any problems, apart from returning invalid
