Again, this is still the wrong way around. A "noiommu" feature is a
quirk and should not be the default.

The J-Core "spi2" device is a PIO-based SPI master controller. It
differs from "bitbang" devices in that that it's clocked in hardware
rather than via soft clock modulation over gpio, and performs
byte-at-a-time transfers between the cpu and SPI controller.
This driver will be extended to support
This driver is used with the J2, an open-source VHDL reimplementation

We blindly trust the hardware to give us NUL-terminated strings, which
is a bad idea because it doesn't always do that. For example:

Add TPM2.0 PTP FIFO compatible SPI interface for chips with Cr50

Secure Microcontroller requires a special driver to handle its
specifics:

This patchset adds support for H1 Secure Microcontroller running

If tpm reports a bigger burstcnt than allowed by the physical protocol,
set burstcnt to the max allowed value.
In practice, seen in case of xfer issues (e.g. in spi interface case,

from TPM_STS). Without catching, causes the

This patchset introduces an optional maximum transfer size that can
be specified by a tpm driver. Setting the max_xfer_size helps to catch
the cases when burstcnt is incorrectly reported by the device (e.g. >64

This patch creates a function flush_tmregs_to_thread which

while in the TM context and logs appropriate warning message.
