This is an extension to the base ISA, but we can use this in

Unknown why this works, but if we return EXCP_ITLB_MISS we
will triple-fault the first userland instruction fetch.
Is it something to do with having a combined I/DTLB?

Linux sets sr4-sr7 all to the same value, which means that we
need not do any runtime computation to find out what space to

Real hardware would use an external device to control the power.
But for the moment let's invent instructions in reserved space,

However since HPPA has a software-managed TLB, and the relevant

Any one TB will have only one space value. If we change spaces,
we change TBs. Thus BE and BEV must exit the TB immediately.

For system mode, we will need 64-bit virtual addresses even when
we have 32-bit register sizes. Since the rest of QEMU equates
TARGET_LONG_BITS with the address size, redefine everything
related to register size in terms of a new TARGET_REGISTER_BITS.

We don't actually do anything with most of the bits yet,

The SPARC code in linux-user/signal.c defines a set of
MC_* constants. On some SPARC hosts these are also defined
by sys/ucontext.h, resulting in build failures:
linux-user/signal.c:2786:0: error: "MC_NGREG" redefined [-Werror]
#define MC_NGREG 19
In file included from /usr/include/signal.h:302:0,

from linux-user/signal.c:19:
/usr/include/sparc64-linux-gnu/sys/ucontext.h:59:0: note: this is the location of the previous definition
# define MC_NGREG __MC_NGREG
Rename all these constants to SPARC_MC_* to avoid the clash.

tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB)
Interface as defined in TCG PC Client Platform TPM Profile (PTP)
Specification Family “2.0” Level 00 Revision 01.03 v22.
The PTP allows device implementation to switch between TIS and CRB
model at run time, but given that CRB is a simpler device to
implement, I chose to implement it as a different device.
The device doesn't implement other locality than 0 for now (my laptop
TPM doesn't either, so I assume this isn't so bad)
Tested with some success with Linux upstream and Windows 10, seabios &
modified ovmf. The device is recognized and correctly transmit
command/response with passthrough & emu. However, we are missing PPI
ACPI part atm.
