2019-10-28hw/m68k: add VIA supportLaurent Vivier
Inside the 680x0 Macintosh, VIA (Versatile Interface Adapter) is used to interface the keyboard, Mouse, and real-time clock. It also provides control line for the floppy disk driver, video interface, sound circuitry and serial interface. This implementation is based on the MOS6522 object.

2019-10-28esp: add pseudo-DMA as used by MacintoshLaurent Vivier
There is no DMA in Quadra 800, so the CPU reads/writes the data from the PDMA register (offset 0x100, ESP_PDMA in hw/m68k/q800.c) and copies them to/from the memory. There is a nice assembly loop in the kernel to do that, see linux/drivers/scsi/mac_esp.c:MAC_ESP_PDMA_LOOP(). The start of the transfer is triggered by the DREQ interrupt (see linux mac_esp_send_pdma_cmd()), the CPU polls on the IRQ flag to start the transfer after a SCSI command has been sent (in Quadra 800 it goes through the VIA2, the via2-irq line and the vIFR register) The Macintosh hardware includes hardware handshaking to prevent the CPU from reading invalid data or writing data faster than the peripheral device can accept it. This is the "blind mode", and from the doc: "Approximate maximum SCSI transfer rates within a blocks are 1.4 MB per second for blind transfers in the Macintosh II" Some references can be found in: Apple Macintosh Family Hardware Reference, ISBN 0-201-19255-1 Guide to the Macintosh Family Hardware, ISBN-0-201-52405-8 Acked-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Co-developed-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Laurent Vivier <laurent@vivier.eu> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20191026164546.30020-4-laurent@vivier.eu>

2019-10-28esp: move handle_ti_cmd() cleanup code to esp_do_dma().Laurent Vivier
To prepare following patches move do_cmd and DMA special case from handle_ti() to esp_do_dma(). This part of the code must be only executed with real DMA, not with pseudo-DMA. And PDMA is detected in esp_do_dma(), so move this part of the code in esp_do_dma(). We keep the code in handle_ti_cmd() in the case no DMA is done.

2019-10-24target/arm: Hoist XSCALE_CPAR, VECLEN, VECSTRIDE in cpu_get_tb_cpu_stateRichard Henderson
We do not need to compute any of these values for M-profile. Further, XSCALE_CPAR overlaps VECSTRIDE so obviously the two sets must be mutually exclusive.

2019-10-24target/arm: Split out rebuild_hflags_a64Richard Henderson
Create a function to compute the values of the TBFLAG_A64 bits that will be cached. For now, the env->hflags variable is not used, and the results are fed back to cpu_get_tb_cpu_state. Note that not all BTI related flags are cached, so we have to test the BTI feature twice -- once for those bits moved out to rebuild_hflags_a64 and once for those bits that remain in cpu_get_tb_cpu_state.
