2013-01-26hw/arm_boot: Align device tree to 4KB boundary, not pagePeter Maydell1-3/+6
Align the device tree blob to a 4KB boundary, not to QEMU's idea of a page boundary -- the latter is the smallest possible page size for the architecture, which on ARM is 1KB. The documentation for Linux does not impose separation or alignment requirements on the device tree blob, but in practice some kernels will happily trash the entire page the initrd ends in after they have finished uncompressing the initrd. So 4KB-align the DTB to ensure it does not get trampled by these kernels. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-12-19janitor: do not rely on indirect inclusions of or from qemu-char.hPaolo Bonzini1-0/+1
Various header files rely on qemu-char.h including qemu-config.h or main-loop.h, but they really do not need qemu-char.h at all (particularly interesting is the case of the block layer!). Clean this up, and also add missing inclusions of qemu-char.h itself. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-11hw/arm_boot, exynos4210, highbank: Fix secondary boot GIC initPeter Maydell1-3/+14
Fix the code in the secondary CPU boot stubs so that it correctly initialises the GIC rather than relying on bugs or implementation dependent aspects of the QEMU GIC implementation: * set the GIC_PMR.Priority field to all-ones, so that all interrupts are passed through. The default of all-zeroes means all interrupts are masked, and QEMU only booted because of a bug in the priority masking in our GIC implementation. * add a barrier after GIC setup and before WFI to ensure that GIC config is complete before we go into a possible low power state. This isn't needed with the software GIC model but could be required when using KVM and executing this code on the real hardware CPU. Note that of the three secondary stub implementations, only the common generic one needs to support both v6 and v7 DSB encodings; highbank and exynos4210 will always be v7 CPUs.

2012-11-01arm_boot: Change initrd load address to "halfway through RAM"Peter Maydell1-15/+25
To avoid continually having to bump the initrd load address to account for larger kernel images, put the initrd halfway through RAM. This allows large kernels on new boards with lots of RAM to work OK, without breaking existing usecases for boards with only 32MB of RAM. Note that this change fixes in passing a bug where we were passing an overly large max_size to load_image_targphys() for the initrd, which meant that we wouldn't correctly refuse to load an enormous initrd that didn't actually fit into RAM.

2010-05-31arm: fix arm kernel boot for non zero start addrLars Munch1-0/+1
Booting an arm kernel has been broken a while when booting from non zero start address. This is due to the order of events: board init loads the kernel and sets register 15 to the start address and then qemu_system_reset reset the cpu making register 15 zero again.

2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno1-2/+2
A few machines need to translate the ELF header addresses into physical addresses. Currently the only possibility is to add a value to the addresses. This patch replaces the addend argument by and a translation function and an opaque passed to the function. A NULL function does not translate the address.
