This reverts commit a5e419c51187d24818f056327746a18676fe3a20.
|
|
Support reading the ACPI GPE status (on x86) to determine when
the cr50 is ready to return response data or is done processing
written data. If the interrupt is not defined by Kconfig then
it will continue to use the safe delay.
This was tested with reef hardware and a modified cr50 image
that generates interrupts at the intended points.

Move the common enums and variables to tpm.h so it can be

The early TPM probe was done directly in tis.c ignoring the lower
layer that provides appropriate access to the chip. Move this into
a tpm_vendor_probe() function so it can use iic_tpm_read() with all
of the built-in delays and semantics instead of calling i2c_readb()
directly from the wrong layer.
This fixes early init failures that were seen with the cr50 i2c tpm
on the reef mainboard.

Use CAR accessors where needed for accessing static data.
In some cases this required some minor restructuring to pass
in a variable instead of use a global one.
For the tpm_vendor_init the structure no longer has useful
defaults, which nobody was depending on anyway. This now
requires the caller to provide a non-zero address.
Tested by enabling I2C TPM on reef and compiling successfully.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

The TPM driver by default allocates a 4K transfer buffer on the stack,
which leads to lots of fun on boards with 2K or 3K stack sizes. On
RK3288 this ends up writing over random memory sections which dependent
on the memlayout of the day might contain timestamp data (no big deal)
or page tables (-> bad time).
This patch fixes the problem by reducing the buffer size to slightly
above 1K, which still seems to work as far as I can tell. There was
already some really odd code that #undef'ed this value and redefined it
with the lower number in one .c file (unfortunately not the one with the
buffer declaration), with no explanation whatsoever... I'm removing that
and just assume the smaller value will be fine for everything.

On ARM platforms the TPM is not attached through LPC but through I2C.
This patch adds an I2C TPM driver that supports the following chips:
* Infineon SLB9635
* Infineon SLB9645
In order to select the correct TPM implementation cleanly, CONFIG_TPM
is moved to src/Kconfig and does the correct choice.

i2c tpm: Remove mostly useless delay code/tables.
I assume from the code in the TPM driver that the TPM spec defines
different types of delays and timeouts which each have a particular
duration, and that the TPM can tell you how long each type is if you ask
it. There was a large table, some members of a data structure, and a
function or two which managed the timeouts and figured their value for
different operations. The timeout values for the various "ordinals"
were never set in the vendor specific data structure, however, and
always defaulted to 2 minutes. Similarly the timeouts a, b, c, and d
were never overridden from their defaults. This change gets rid of all
the timeout management code and makes the "ordinal" timeout 2 minutes
and the a, b, c, and d timeouts 2 seconds, the larger of the two default
values.
This is a port from depthcharge to coreboot, original change:

TPM: Stop requesting/releasing the TPM locality.
The locality is requested when the TPM is initialized and released when
it's cleaned up. There's no reason to set it to the same thing again and
restore it back to the same value before and after every transaction.
