If the set of targets are all little or all big endian, re-declare the device endianness as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN respectively. This *naive* deduction may result in genuinely native endian devices being incorrectly declared as little or big endian, but should not introduce regressions for current targets. These devices should be re-declared as DEVICE_NATIVE_ENDIAN if 1) it has a new target with an opposite endian or 2) someone informed knows better =3D) Signed-off-by: Tony Nguyen --- hw/display/pl110.c | 2 +- hw/display/tc6393xb.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/hw/display/pl110.c b/hw/display/pl110.c index c2991a28d2..3831505165 100644 --- a/hw/display/pl110.c +++ b/hw/display/pl110.c @@ -473,7 +473,7 @@ static void pl110_write(void *opaque, hwaddr offset, static const MemoryRegionOps pl110_ops =3D { .read =3D pl110_read, .write =3D pl110_write, - .endianness =3D DEVICE_NATIVE_ENDIAN, + .endianness =3D DEVICE_LITTLE_ENDIAN, }; =20 static void pl110_mux_ctrl_set(void *opaque, int line, int level) diff --git a/hw/display/tc6393xb.c b/hw/display/tc6393xb.c index 49a676d1b0..6a9477a0c7 100644 --- a/hw/display/tc6393xb.c +++ b/hw/display/tc6393xb.c @@ -549,7 +549,7 @@ TC6393xbState *tc6393xb_init(MemoryRegion *sysmem, uint= 32_t base, qemu_irq irq) static const MemoryRegionOps tc6393xb_ops =3D { .read =3D tc6393xb_readb, .write =3D tc6393xb_writeb, - .endianness =3D DEVICE_NATIVE_ENDIAN, + .endianness =3D DEVICE_LITTLE_ENDIAN, .impl =3D { .min_access_size =3D 1, .max_access_size =3D 1, --=20 2.23.0
