Upstream commit 4370eec05a88 "arm64: Expand arm64 image header" ended up changing the zImage magic (which was actually the initial branch instructio encoding!). The new header has a proper magic number at a fixed location. Switch Xen itself to using this format. Neither the bootwrapper nor the models care about this header themselves and real bootloaders are not widely used, so now is as good a time as any to switch (as upstream have proven) Signed-off-by: Ian Campbell <ian.campbell@xxxxxxxxxx> --- xen/arch/arm/arm64/head.S | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/xen/arch/arm/arm64/head.S b/xen/arch/arm/arm64/head.S index 1d04efc..5ffe4f4 100644 --- a/xen/arch/arm/arm64/head.S +++ b/xen/arch/arm/arm64/head.S @@ -108,6 +108,14 @@ start: .quad 0 /* Image load offset from start of RAM */ .quad 0 /* reserved */ .quad 0 /* reserved */ + .quad 0 /* reserved */ + .quad 0 /* reserved */ + .quad 0 /* reserved */ + .byte 0x41 /* Magic number, "ARM\x64" */ + .byte 0x52 + .byte 0x4d + .byte 0x64 + .word 0 /* reserved */ real_start: msr DAIFSet, 0xf /* Disable all interrupts */ -- 1.7.10.4 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
