This patch provides a new device driver for the Infineon SLD 9630 TT Trusted
Platform Module (TPM 1.1b) [1] which is embedded on Intel- mainboards or in
HP/ Fujitsu-Siemens / Toshiba-Notebooks. A nearly complete list where this
module is integrated in can be found in [2].
This kernel module acts as a communication gateway between the linux kernel
and the hardware chip and fits the TPM-specific interfaces created by IBM in
drivers/char/tpm/tpm.h
Further information about this module and a list of succesfully tested and
therefore supported hardware can be found at our project page [3].

The FBA discipline does not use retries for failed requests. A request fails
after the first unsuccessful start attempt. There are some rare conditions
(e.g. CIO path recovery) in which the start of an i/o on a fba device can

This patch fixes a microcode lockup in my CD-ROM adapters when a blank CD
is inserted. However, do not try to burn CDs yet! I'm pretty sure that
trying it will end in coasters.
- Fix a few cases where we were unable to resynchronize with replies
for previous commands. The main thing is to keep reading replies
in case of a stall. This is done with the new state CLRRS.
- Since I am forgetting the basic state machine already, document it.
- Move counter increments in the looping path in its own function.
- Fix a harmless buglet in case CSW read fails to submit: do not
override state.

This resolves entry #4863 in the OSDL bugzilla. Although in that bug
report the failure occurred because of a confusion over scanning vs.

simplest being insufficient memory) and the caller should cope properly.
