2013-12-17target-arm: Define and use ARM_FEATURE_CBARPeter Crosthwaite
Some processors (notably A9 within Highbank) define and use the CP15 configuration base address (CBAR). This is vendor specific so its best implemented as a CPU property (otherwise we would need vendor specific child classes for every ARM implementation). This patch prepares support for converting CBAR reset value to a CPU property by moving the CP registration out of the CPU init fn, as registration will need to happen at realize time to pick up any property updates. The easiest way to do this is via definition of a new ARM_FEATURE to flag the existence of the register.

2013-12-17Fix NOR flash device ID readingRoy Franz
Fix NOR flash manufacturer and device ID reading. This now properly takes into account device widths and device max widths as required. The reading of these IDs uses the same max_width dependent addressing as CFI queries. The old code remains for chips that don't specify a device width, as the new code relies on a device width being set in order to properly operate. The existing code seems very broken. Only ident0 and ident1 are used in the new code, as other fields relate to the lock state of blocks in flash. The VExpress flash configuration has been updated to match the new code, as the existing definition was 'wrong' in order to return the expected results with the broken device ID code.

2013-12-17Fix CFI query responses for NOR flashRoy Franz
This change fixes the CFI query responses to handle NOR device widths that are different from the bank width. Support is also added for multi-width devices in a x8 configuration. This is typically x8/x16 devices, but the CFI specification mentions x8/x32 devices so those should be supported as well if they exist. The query response data is now replicated per-device in the bank, and is adjusted for x16 or x32 parts configured in x8 mode. The existing code is left in place for boards that have not been updated to specify an explicit device_width. The VExpress board has been updated in an earlier patch in this series so this is the only board currently affected.

2013-12-17Add max device width parameter for NOR devicesRoy Franz
For handling CFI and device ID reads, we need to not only know the width that a NOR flash device is configured for, but also its maximum width. The maximum width addressing mode is used for multi-width parts no matter which width they are configured for. The most common case is x16 parts that also support x8 mode. When configured for x8 operation these devices respond to CFI and device ID requests differently than native x8 NOR parts.

2013-12-17Add device-width property to pflash_cfi01Roy Franz
The width of the devices that make up the flash interface is required to mask certain commands, in particular the write length for buffered writes. This length will be presented to each device on the interface by the program writing the flash, and the flash emulation code needs to be able to determine the length of the write as recieved by each flash device. The device-width defaults to the bank width which should maintain existing behavior for platforms that don't need this change. This change is required to support buffered writes on the vexpress platform that has a 32 bit flash interface with 2 16 bit devices on it.

qemu_opts_parse() can always return NULL, even if the QemuOptsList.desc in question would be trivial to satisfy (eg. because it's empty).

And pin 16~23 can be assigned to hpet as guest chooses. So we introduce intcap property to do that.

2013-12-11pci: fix pci bridge fw pathGerd Hoffmann
qemu uses "pci" as name for pci bridges in the firmware device path. seabios expects "pci-bridge". Result is that bootorder is broken for devices behind pci bridges. Some googling suggests that "pci-bridge" is the correct one. At least PPC-based Apple machines are using this. See question "How do I boot from a device attached to a PCI card" here: http://www.netbsd.org/ports/macppc/faq.html So lets change qemu to use "pci-bridge" too.
