Igor Mammedov b9ad9d5b21 tricore: cleanup cpu type name composition
introduce TRICORE_CPU_TYPE_NAME macro and use it to construct
cpu type names. While at it move cpu type_infos into one
array and register it directly with type_init_from_array()
instead of custom tricore_cpu_register_types()/cpu_register()

Eduardo Otubo b190f477e2 qemu-system-tricore: segfault when entering "x 0" on the monitor
Starting Qemu with "qemu-system-tricore -nographic -M tricore_testboard -S"
and entering "x 0" at the monitor prompt leads to Segmentation fault.
This happens because tricore_cpu_get_phys_page_debug() is not implemented
yet, this is a temporary workaround to avoid the crash.

Alex Bennée 1f5c00cfdb qom/cpu: move tlb_flush to cpu_common_reset
It is a common thing amongst the various cpu reset functions want to
flush the SoftMMU's TLB entries. This is done either by calling
tlb_flush directly or by way of a general memset of the CPU
structure (sometimes both).

This moves the tlb_flush call to the common reset function and
additionally ensures it is only done for the CONFIG_SOFTMMU case and
when tcg is enabled.

In some target cases we add an empty end_of_reset_fields structure to the
target vCPU structure so have a clear end point for any memset which
is resetting value in the structure before CPU_COMMON (where the TLB
structures are).

While this is a nice clean-up in general it is also a precursor for
changes coming to cputlb for MTTCG where the clearing of entries
can't be done arbitrarily across vCPUs. Currently the cpu_reset
function is usually called from the context of another vCPU as the
architectural power up sequence is run. By using the cputlb API
functions we can ensure the right behaviour in the future.

Thomas Huth fcf5ef2ab5 Move target-* CPU file into a target/ folder
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
