2014-01-31hw/arm/boot: Don't set up ATAGS for autogenerated dtb bootingPeter Maydell1-2/+7
The code which decides whether to set up the ATAGS data structure on reset was using the wrong conditional, which meant we were creating an ATAGS structure when doing a device-tree boot if the dtb was autogenerated by the board. This is harmless, but unnecessary, so bring it in to line with user-provided-dtb boots.

2013-12-17hw/arm/boot: Add boot support for AArch64 processorMian M. Hamayun1-5/+38
This commit adds support for booting a single AArch64 CPU by setting appropriate registers. The bootloader includes placeholders for Board-ID that are used to implement uniform indexing across different bootloaders. Signed-off-by: Mian M.

2013-12-17hw/arm/boot: Allow easier swapping in of different loader codePeter Maydell1-45/+107
For AArch64 we will obviously require a different set of primary and secondary boot loader code fragments. However currently we hardcode the offsets into the loader code where we must write the entrypoint and other data into arm_load_kernel(). This makes it hard to substitute a different loader fragment, so switch to a more flexible scheme where instead of a raw array of instructions we use an array of (instruction, fixup-type) pairs that indicate which words need special action or data written into them.

2013-10-31hw/arm/boot: Make user not specifying a kernel not an errorPeter Maydell1-2/+4
Typically ARM boards will have some kind of flash which might contain a boot ROM; it's therefore a valid use case to provide only an image for the boot ROM and not require QEMU's internal boot loader at all. Remove the fatal error if -kernel isn't specified. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1379980897-21277-2-git-send-email-peter.maydell@linaro.org

Add a callback hook in arm_boot_info to allow board models to modify the device tree blob if they need to.

2013-06-25arm/boot: Free dtb blob memory after usePeter Maydell1-5/+15
The dtb blob returned by load_device_tree() is in memory allocated with g_malloc(). Free it accordingly once we have copied its contents into the guest memory. To make this easy, we need also to clean up the error handling in load_dtb() so that we consistently handle errors in the same way (by printing a message and then returning -1, rather than either plowing on or exiting immediately).
