The 'struct tm now' field in the state structure is in fact only ever used as a temporary (the actual RTC state is held in 'offset'). Remove it from the state structure in favour of using local variables to avoid confusion about whether it needs to be saved on migration. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

The DS1338 datasheet documents that the current time is captured into the secondary registers when the register pointer wraps round to zero as well as at a START condition. Implement this. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Correct several deficiencies in the handling of the register pointer: * it should wrap around after 0x3f, not 0xff * guard against the caller handing us an out of range pointer (on h/w this can never happen, because only a 7 bit value is transferred over the I2C bus) * there was confusion over whether nvram[] holds only the 56 bytes of guest-accessible NVRAM, or also the secondary registers which hold the value of the clock captured at the start of a multibyte read. Correct to consistently be the latter, by fixing the array size and the offset used for NVRAM writes. * ds1338_send was attempting to use 'data' as both the data and the register offset simultaneously, which meant that writes to any register were broken; fix to use the register pointer.

s->cpu_enabled is an array, so s->cpu_enabled ? "En" : "Dis" returns "En" always. We should use s->cpu_enabled[cpu] here. Signed-off-by: NEvgeny Voevodin <e.voevodin@samsung.com> Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

A missing call to qemu_set_irq() when reading the IRQ register required SW to write to the IRQ register to acknowledge an interrupt. With this patch the behavior is fixed: - Reading the interrupt register clears it and updates the timers interrupt status - Writes to the interrupt register are ignored Signed-off-by: NSoren Brinkmann <soren.brinkmann@xilinx.com> Signed-off-by: NPeter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Added helper function to automatically connect SPI slaves based on the QOM child nodes of a device. A SSI master device can call this routine to automatically hook-up all child nodes to its SPI bus.

Allow multiple qdev_init_gpio_in() calls for the one device. The first call will define GPIOs 0-N-1, the next GPIOs N- ... . Allows different GPIOs to be handled with different handlers. Needed when two levels of the QOM class heirachy both define GPIO functionality, as a single GPIO handler with an index selecter is not possible. Signed-off-by: NPeter A. G.

Added default CS behaviour for SSI slaves. SSI devices can set a property to enable CS behaviour which will create a GPIO on the device which is the CS. Tristating of the bus on SSI transfers is implemented. Signed-off-by: NPeter A. G. Crosthwaite <peter.crosthwaite@petalogix.com> Acked-by: NPeter Maydell <peter.maydell@linaro.org>

Removed assertion that only one device is attached to the SSI bus. When multiple devices are attached, all slaves have their transfer function called for transfers. Each device is responsible for knowing whether or not its CS is active, and if not returning 0. The returned data is the logical or of all responses from the (mulitple) devices.

There are 6 temporaries that disas_sparc_insn relies on having been allocated. Now that they are no longer referenced across branches, they need not be allocated as local temps.

Share more code between unconditional and conditional paths.
