The cpu_to_gt32 macro wants to byteswap a value for little endian targets only, but uses the wrong way to do this: cpu_to_[lb]e32 works the other way round on big endian hosts! Fix it by using the same ways on both, big and little endian hosts. Fixes: 0c8427baf0 ("hw/mips/malta: Use bootloader helper to set BAR registe= rs") Signed-off-by: Thomas Huth Reviewed-by: Peter Maydell --- I've checked that both, the kernel from https://landley.net/toybox/downloads/binaries/mkroot/0.8.9/mipsel.tgz and the kernel from https://landley.net/toybox/downloads/binaries/mkroot/0.8.9/mips.tgz now boot fine on both, a little endian (x86) and a big endian (s390x) host. hw/mips/malta.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/hw/mips/malta.c b/hw/mips/malta.c index af9021316d..b26ed1fc9a 100644 --- a/hw/mips/malta.c +++ b/hw/mips/malta.c @@ -629,9 +629,9 @@ static void bl_setup_gt64120_jump_kernel(void **p, uint= 64_t run_addr, =20 /* Bus endianess is always reversed */ #if TARGET_BIG_ENDIAN -#define cpu_to_gt32 cpu_to_le32 +#define cpu_to_gt32(x) (x) #else -#define cpu_to_gt32 cpu_to_be32 +#define cpu_to_gt32(x) bswap32(x) #endif =20 /* setup MEM-to-PCI0 mapping as done by YAMON */ --=20 2.31.1
