10 years agoIntroduce generic TPM support in u-boot
Vadim Bendebury [Mon, 17 Oct 2011 08:36:14 +0000 (08:36 +0000)]
Introduce generic TPM support in u-boot

TPM (Trusted Platform Module) is an integrated circuit and
software platform that provides computer manufacturers with the
core components of a subsystem used to assure authenticity,
integrity and confidentiality.

This driver supports version 1.2 of the TCG (Trusted Computing
Group) specifications.

The TCG specification defines several so called localities in a
TPM chip, to be controlled by different software layers. When
used on a typical x86 platform during the firmware phase, only
locality 0 can be accessed by the CPU, so this driver even while
supporting the locality concept presumes that only locality zero
is used.

This implementation is loosely based on the article "Writing a
TPM Device Driver" published on http://ptgmedia.pearsoncmg.com

Compiling this driver with DEBUG defined will generate trace of
all accesses to TMP registers.

This driver has been tested and is being used in three different
functional ChromeOS machines (Pinetrail and Sandy Bridge Intel
chipsets) all using the same Infineon SLB 9635 TT 1.2 device.

A u-boot cli command allowing access to the TPM was also
implemented and is being submitted as a second patch.

Change the CONFIG_SYS_TEXT_BASE and the addresses of SDRAM

following requirements:

1. Make sure that SPL's heap and BSS doesn't come in the way
of Linux kernel, which is typically loaded at 0x80008000. This
will be important when SPL directly loads kernel.

2. Align the CONFIG_SYS_TEXT_BASE between TI internal
U-Boot and mainline U-Boot. This avoids a lot of confusion
and allows for the inter-operability of x-loader, SPL,
internal U-Boot, mainline U-Boot etc. The internal U-Boot's
address can not be changed to that of mainline U-Boot
as internal U-Boot doesn't have relocation and 0x80100000
used by mainline U-Boot will clash with kernel

3. Assume only a minimum amount of memory that may be available
on any practical OMAP4/5 board in future too. We are assuming
a minimum of 128 MB of memory

CP15 System Control register. Apparently this is not
enough.

The bootstrap loader in Linux kernel that does decompression
enables data-caches again, flush them after use and disable
them before jumping to kernel proper. However, it's not aware
of the external caches.

Since we have left external cache enabled, external cache will
get used once caches are enabled globally, but it's not flushed
because decompressor is not aware of external caches. When it
jumps to kernel with caches disabled globally, we have stale
data in the external cache and a coherency problem.
