Subject: Re: [PATCH v2 10/10] sandbox: tpm: Support extending a PCR multiple times
Date: Sat, 24 Jul 2021 14:11:57 -0700	[thread overview]
Message-ID: <CAPnjgZ0v9CZ8nQWOpUnMPg6w-tMR-Dt=Hhkr5atKGV2m+8kv-w@mail.gmail.com> (raw)
In-Reply-To: <20210718201806.761202-11-sjg@chromium.org>

It is fairly easy to handle this case and it makes the emulator more
useful, since PCRs are commonly extended several times.

Add support for this, using U-Boot's sha256 support.

For now sandbox only supports a single PCR, but that is enough for the
tests that currently exist.

Signed-off-by: Simon Glass <sjg@chromium.org>

Changes in v2:
- Drop the constant sandbox_extended_once_pcr since we can calculate it
- Update the commit message to explain that there is only one PCR

Applied to u-boot-dm, thanks!
