2009-06-16Remove io_index argument from cpu_register_io_memory()Avi Kivity
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. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-13Include assert.h from qemu-common.hPaul Brook
Include assert.h from qemu-common.h and remove other direct uses. cpu-all.h still need to include it because of the dyngen-exec.h hacks Signed-off-by: Paul Brook <paul@codesourcery.com>

2008-12-07SH4: SCI improvementaurel32
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.

2008-12-07SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).balrog
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.

2008-11-21SH4: Switch serial emulation to qemu_irqaurel32
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.
