tpm: measure DTB in PCR1 instead of PCR0

2024-06-16T07:45:57+00:00

The PC client spec [0], doesn't describe measurements for DTBs. It does
describe what do to for ACPI tables though.

There is a description for ACPI in 3.3.4.1 PCR[0] – SRTM, POST BIOS,
and Embedded Drivers and they explicitly mention ACPI in there. There's
no mention of ACPI in 3.3.4.2 PCR[1] – Host Platform Configuration.

However, in Figure 6 --  PCR Mapping of UEFI Components ACPI is shown
in PCR1. The general description also mentions PCR0 is for code and PCR1
is for data such as ACPI and SMBIOS.

So let's switch over the DTB measurements to PCR1 which seems a better
fit.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

boot: fdt: Change type of env_get_bootm_low() to phys_addr_t

2024-04-11T15:38:57+00:00

Change type of ulong env_get_bootm_low() to phys_addr_t env_get_bootm_low().
The PPC/LS systems already treat env_get_bootm_low() result as phys_addr_t,
while the function itself still returns ulong. This is potentially dangerous
on 64bit systems, where ulong might not be large enough to hold the content
of "bootm_low" environment variable. Fix it by using phys_addr_t, similar to
what env_get_bootm_size() does, which returns phys_size_t .

boot: Support decompressing non-kernel OS images

2024-01-12T02:19:25+00:00

Sometimes the kernel is built as an EFI application rather than a
binary. We still want to support compression for this case.

For arm64 the entry point is set later in the bootm_load_os() function,
since these images are typically relocated due to the 2MB-alignment
requirement of arm64 images. But since the EFI image is not in the same
format, we need to update the entry point earlier.

Set the entry point always, for kernel_noload to resolve this problem.
It should be harmless to do this always.

Merge patch series "Complete decoupling of bootm logic from commands"

2023-12-21T21:10:00+00:00

Simon Glass  says:

This series continues refactoring the bootm code to allow it to be used
with CONFIG_COMMAND disabled. The OS-handling code is refactored and
a new bootm_run() function is created to run through the bootm stages.
This completes the work.

A booti_go() function is created also, in case it proves useful, but at
last for now standard boot does not use this.

This is cmdd (part d of CMDLINE refactoring)
It depends on dm/bootstda-working
which depends on dm/cmdc-working

bootm: Create a new boot_run() function to handle booting

Create a common function used by the three existing bootz/i/m_run()
functions, to reduce duplicated code.

bootm: Create a function to run through the booti states

In a few places, the booti command is used to handle a boot. We want
these to be done without needing CONFIG_CMDLINE, so add a new
booti_run() function to handle this.

So far this is not used.
