2021-09-14multiboot2: Avoid first 0x500 bytesZhaofeng Li
In some cases, add_buffer will actually try to allocate the buffer at 0x0, which may not be acceptable by some kernels. Let's avoid the first 0x500 bytes so we don't screw up the IVT and BDA. Signed-off-by: Zhaofeng Li <hello@zhaofeng.li> Signed-off-by: Simon Horman <horms@verge.net.au>
2021-09-14multiboot2: Use rel_min and rel_max for buffer destinationsZhaofeng Li
This would segfault if mhi.rel_tag didn't exist. Signed-off-by: Zhaofeng Li <hello@zhaofeng.li> Signed-off-by: Simon Horman <horms@verge.net.au>
2021-09-14multiboot2: Correct MBI size calculationZhaofeng Li
tag_load_base_addr is dependent on rel_tag, and tag_framebuffer was not accounted for. Signed-off-by: Zhaofeng Li <hello@zhaofeng.li> Signed-off-by: Simon Horman <horms@verge.net.au>

2020-04-07kexec: Introduce --load-live-update for xenVarad Gautam
Support loading a live update image for xen from kexec userspace. For a multiboot2 Elf on a xen setup, this will: - load the Elf into KEXEC_RANGE_MA_XEN - load purgatory and modules into KEXEC_RANGE_MA_LIVEUPDATE - append the Elf cmdline with " liveupdate=<size>@<addr> v2: define xen related symbols outside of HAVE_LIBXENCTRL Signed-off-by: Varad Gautam <vrd@amazon.de> Signed-off-by: Simon Horman <horms@verge.net.au>
