Alexander Graf 2507c12ab0 Add endianness as io mem parameter
As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.

This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

Blue Swirl 43dc2a645e 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.

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b72.

Avi Kivity 1eed09cb4a Remove io_index argument from cpu_register_io_memory()
The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty).  Remove the parameter to reduce
the API's power, thus facilitating future change.

aurel32 d1f193b0ed SH4: SCI improvement
This patch simply implement one register of SH4's SCI := Serial Communication Interface.

R2D evaluation board uses SCI for SPI connection.  So, Linux kernel for R2D with
default configuration causes a QEMU assertion failure when it initializes SPI driver.
This patch avoids it and reduces the kernel config modification work for QEMU.

Completing SCI implementation task is left.  Other board support is desirable to confirm
this task, which uses SCI for a serial terminal.

balrog 5c16736a37 SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).
Main purpose of this is to delete
       *physical = address & 0x1fffffff;
at target-sh4/helper.c:449, using new mmio rule introduced by #5849
This masking is a nice trick to realize P4/A7 duality of SH registers.
But, IMHO, it is logically wrong.

Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have
one more address called A7 which is usually P4 address with upper 3bits masked.
This is an address only appears in TLB's physical address part.

Current code use trick writing drivers as if they are really in A7
(that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

aurel32 4e7ed2d1d3 SH4: Switch serial emulation to qemu_irq
This patches makes SH serial emulation use qemu_irq in its interface.

        * hw/sh.h (sh_serial_init): Take qemu_irq, not intc_source.
        * hw/sh7750.c (sh7750_init): Adjust.
        * hw/sh_intc.c (sh_intc_set_irq): Don't assert or deassert
        irq more than once.
        * hw/sh_serial.c (sh_serial_state): Use qemu_irq, not intc_source.
        (sh_serial_clear_fifo, sh_serial_ioport_write)
        (sh_serial_receive_byte): Adjust.
        (sh_serial_init): Take qemu_irq, not intc_source.
