2012-02-17hw/vexpress.c: Add vexpress-a15 machinePeter Maydell1-0/+141
Add the vexpress-a15 machine, and the A-Series memory map it uses. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de>
2012-02-17arm_boot: Pass base address of GIC CPU interface, not whole GICPeter Maydell1-2/+4
The arm_boot secondary boot loader code needs the address of the GIC CPU interface. Obtaining this from the base address of the private peripheral region was possible for A9 and 11MPcore, but the A15 puts the GIC CPU interface in a different place. So make boards pass in the GIC CPU interface address directly. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-02-17hw/vexpress.c: Instantiate the motherboard CLCDPeter Maydell1-1/+1
Instantiate the CLCD on the vexpress motherboard as well as one on the daughterboard -- the A15 daughterboard does not have a CLCD and so relies on the motherboard one. At the moment QEMU doesn't provide infrastructure for selecting which display device gets to actually show graphics -- the first one registered is it. Fortunately this works for the major use case (Linux): if the daughterboard has a CLCD it will come first and be used, otherwise we fall back to the motherboard CLCD. So we don't (currently) need to implement the control register which allows software to tell the mux which video output to pass through to the outside world.

2012-02-17hw/vexpress.c: Factor out daughterboard-specific initializationPeter Maydell1-35/+83
Factor out daughterboard specifics into a data structure and daughterboard initialization function, in preparation for adding vexpress-a15 support. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-02-17hw/vexpress.c: Move secondary CPU boot code to SRAMPeter Maydell1-14/+2
On real Versatile Express hardware, the boot ROM puts the secondary CPU bootcode/holding pen in SRAM. We can therefore rely on Linux not trashing this memory until secondary CPUs have booted up, and can put our QEMU-specific pen code in the same place. This allows us to drop the odd "hack" RAM page we were using before. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-02-17hw/vexpress.c: Make motherboard peripheral memory map table-drivenPeter Maydell1-34/+103
Pull the addresses used for mapping motherboard peripherals into memory out into a table. This will allow us to simply provide a second table to implement the "Cortex-A Series" memory map used by the A15 variant of Versatile Express, as well as the current "Legacy" map used by A9.

2012-02-09ARM devboards: Set arm_sysctl properties before init, not afterPeter Maydell1-1/+1
The ARM devboard models (vexpress-a9, realview, versatilepb, etc) were accidentally trying to set one of the arm_sysctl properties after device init. This has now become a fatal error; set the property before device init where it should be done instead. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-01-17vexpress, realview: Add (dummy) L2 cache controllerPeter Maydell1-0/+1
Instantiate the L2 cache controller on the ARM devboards which have one, since we have a dummy model of it now. Note that the only non-MP board with an L2x0 is the PB1176, which we don't model. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-01-17hw/arm_boot.c: Make SMP boards specify address to poll in bootup loopEvgeny Voevodin1-0/+2
The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a pen until the primary CPU releases them. Make boards specify the address to be polled to determine whether to leave the pen (it was previously hardcoded to 0x10000030, which is a Versatile Express/ Realview specific system register address).

2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity1-4/+8
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>
