target-sh4: improve TLB

SH4 is using 16-bit instructions which means most of the constants are
loaded through a constant pool at the end of the subroutine. The same
memory page is therefore accessed in exec and read mode.

With the current implementation, a QEMU TLB entry is set to read or...

target-sh4: implement writes to mmaped ITLB

Some Linux kernels seems to implement ITLB/UTLB flushing through by
writing all TLB entries through the memory mapped interface instead
of writing one to MMUCR.TI.

Implement memory mapped ITLB write interface so that such kernels can...

target-sh4: Split the LDST macro into 2 sub-macros

The LDST macro is used to generate ldc and stc instructions that work with a
specific register. However, the SGR register only supports stc up to SH4A,
which supports both stc and ldc. This patch creates two sub-macros named LD...

Replace assert(0) with abort() or cpu_abort()

When building with -DNDEBUG, assert(0) will not stop execution
so it must not be used for abnormal termination.

Use cpu_abort() when in CPU context, abort() otherwise.
