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 =) Signed-off-by: Tony Nguyen --- hw/gpio/pl061.c | 2 +- hw/gpio/zaurus.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/hw/gpio/pl061.c b/hw/gpio/pl061.c index 2a828260bd..25371d6c5a 100644 --- a/hw/gpio/pl061.c +++ b/hw/gpio/pl061.c @@ -341,7 +341,7 @@ static void pl061_set_irq(void * opaque, int irq, int level) static const MemoryRegionOps pl061_ops = { .read = pl061_read, .write = pl061_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_LITTLE_ENDIAN, }; static void pl061_luminary_init(Object *obj) diff --git a/hw/gpio/zaurus.c b/hw/gpio/zaurus.c index 9a12c68342..60bbbb8564 100644 --- a/hw/gpio/zaurus.c +++ b/hw/gpio/zaurus.c @@ -157,7 +157,7 @@ static void scoop_write(void *opaque, hwaddr addr, static const MemoryRegionOps scoop_ops = { .read = scoop_read, .write = scoop_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_LITTLE_ENDIAN, }; static void scoop_gpio_set(void *opaque, int line, int level)
