Define a UCLASS API for verifying ECDSA signatures. Unlike
UCLASS_MOD_EXP, which focuses strictly on modular exponentiation,
the ECDSA class focuses on verification. This is done so that it
better aligns with mach-specific implementations, such as stm32mp.

What is the plan for the U-Boot run-time test for this? I think it is
in progress, right?

Prepare the source tree for accepting implementations of the ECDSA
algorithm. This patch deals with the boring aspects of Makefiles and
Kconfig files.

Since we are using Kconfig now, can we drop this IMAGE_... stuff and
just use CONFIG_IS_ENABLED() in the code?

I wonder if that and IS_ENABLED() can be fixed?

Not super easily? Some sort of seeing about cleaning up the code we
share with userspace would be nice, yes. But it should also probably
means that for the user side of things we always enable a bunch of stuff
so that in the end we end up with (nearly) target-agnostic tools.

(just to be clear, this discussion should not hold up this patch IMO)
Yes and in fact at present we allow some things to be disabled in
tools where we probably should not.
My original question was about CONFIG_IS_ENABLED(). I wonder if it
doesn't work because the CONFIG is not enabled or because of some
other reason?

Simon

CONFIG_IS_ENABLED() macro isn't available when compiling host tools. I
suspect nobody implemented it host-side?

I think it should map to IS_ENABLED(). But also, do we include
kconfig.h in the tools?

Just a note that I sent a series to enable CONFIG_IS_ENABLED on the host.

Normally the series that is reviewed first is applied first, then it
is up to the subsequent series (i.e. mine) to rebase on that. It gets
a bit out of hand if people send a patch, it is reviewed, then it has
to be reworked later after someone does another patch that didn't
exist then! I am sure it happens sometimes, though. It's up to Tom.
Having said that, if you can do a fix-up patch on top of my series I
think it would be handy.

Simon

I'd rather work with you than race condition against you. If you're
willing to plow through review on your series, and get it merged soon,
I'll take the red pill and rebase my series.

Implement the crypto_algo .verify() function for ecdsa256. Because
it backends on UCLASS_ECDSA, this change is focused on parsing the
keys from devicetree and passing this information to the specific
UCLASS driver.

The STM32MP ROM provides several service. One of them is the ability
to verify ecdsa256 signatures. Hook the ROM API into the ECDSA uclass.

FIT signatures can now be implemented with ECDSA. The assumption that
all FIT images are signed with RSA is no longer valid. Thus, instead
of 'select'ing RSA, only 'imply' it. This doesn't change the defaults,
but allows one to explicitly disable RSA support.

This test verifies that ECDSA_UCLASS is implemented, and that
ecdsa_verify() works as expected. The definition of "expected" is
"does not find a device, and returns -ENODEV".
The lack of a hardware-independent ECDSA implementation prevents us
from having one in the sandbox, for now.
