2014-06-19hw/arm/vexpress: Forbid specifying flash contents in two ways at oncePeter Maydell
Detect attempts by the user to specify the contents of the first flash device via both -bios and -drive if=pflash... simultaneously and print a helpful error message. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1402419834-25982-1-git-send-email-peter.maydell@linaro.org
2014-06-09vexpress: Add support for the -bios flag to provide firmwareGrant Likely
Right now to run firmware inside the QEMU VExpress model requires padding out the firmware image to the size of the virtual flash and passing it in via the -pflash argument. If the firmware image is passed without padding, then QEMU will fail. Also, when passed as a -pflash argument, QEMU treats the file as persistent storage and will modify the file. The -bios flag provides the semantics that we want for providing a firmware image. This patch maps the contents of the -bios file into the address space at the boot flash location. Tested with the vexpress-a15 model and the Tianocore port.

2014-05-28machine: Conversion of QEMUMachineInitArgs to MachineStateMarcel Apfelbaum
Total removal of QEMUMachineInitArgs struct. QEMUMachineInitArgs's fields are copied into MachineState. Removed duplicated fields from MachineState.

2014-04-04hw/arm/vexpress, hw/arm/highbank: Don't insist that CPU has reset-cbar propertyPeter Maydell
For the machine models which can have a Cortex-A15 CPU (vexpress-a15 and midway), silently continue if the CPU object has no reset-cbar property rather than failing. This allows these boards to be used under KVM with the "-cpu host" option, since the 'host' CPU object has no reset-cbar property.

2014-03-17vexpress: Set reset-cbar property for CPUsPeter Maydell
Newer versions of the Linux kernel (as of commit bc41b8724 in 3.12) now assume that if the CPU is a Cortex-A9 and the reset value of the PERIPHBASE/CBAR register is zero then the CPU is a specific buggy single core A9 SoC, and will not try to start other cores. Since we now have a CPU property for the reset value of the CBAR, we can just fix the vexpress board model to correctly set CBAR so SMP works again. To avoid duplicate boilerplate code in both the A9 and A15 daughterboard init functions, we split out the CPU and private memory region init to its own function.

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.

2013-08-28hw: Clean up bogus default boot orderMarkus Armbruster
We set default boot order "cad" in every single machine definition except "pseries" and "moxiesim", even though very few boards actually care for boot order, and "cad" makes sense for even fewer. Machines that care: * pc and its variants Accept up to three letters 'a', 'b' (undocumented alias for 'a'), 'c', 'd' and 'n'. Reject all others (fatal with -boot). * nseries (n800, n810) Check whether order starts with 'n'. Silently ignored otherwise. * prep, g3beige, mac99 Extract the first character the machine understands (subset of 'a'..'f'). Silently ignored otherwise. * spapr Accept an arbitrary string (vl.c restricts it to contain only 'a'..'p', no duplicates). * sun4[mdc] Use the first character. Silently ignored otherwise. Strip characters these machines ignore from their default boot order. For all other machines, remove the unused default boot order alltogether. Note that my rename of QEMUMachine member boot_order to default_boot_order and QEMUMachineInitArgs member boot_device to boot_order has a welcome side effect: it makes every use of boot orders visible in this patch, for easy review.

2013-07-15hw/arm/vexpress: Add alias for flash at address 0 on A15 boardPeter Maydell
The A15 Versatile Express board can remap a variety of things at address 0. We don't currently emulate the Serial Configuration Controller which is how the guest can control this remapping, but we can provide the initial default mapping of the first flash device into this space. In particular this allows QEMU to boot flash images such as UEFI which expect to include an exception vector table.

Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
