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/char/cadence_uart.c | 2 +- hw/char/escc.c | 2 +- hw/char/etraxfs_ser.c | 2 +- hw/char/grlib_apbuart.c | 2 +- hw/char/imx_serial.c | 2 +- hw/char/lm32_uart.c | 2 +- hw/char/milkymist-uart.c | 2 +- hw/char/pl011.c | 2 +- 8 files changed, 8 insertions(+), 8 deletions(-) -- 1.8.3.1 ? diff --git a/hw/char/cadence_uart.c b/hw/char/cadence_uart.c index fa25fe2..6c7b904 100644 --- a/hw/char/cadence_uart.c +++ b/hw/char/cadence_uart.c @@ -457,7 +457,7 @@ static uint64_t uart_read(void *opaque, hwaddr offset, static const MemoryRegionOps uart_ops = { .read = uart_read, .write = uart_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_LITTLE_ENDIAN, }; static void cadence_uart_reset(DeviceState *dev) diff --git a/hw/char/escc.c b/hw/char/escc.c index 8ddbb4b..36182d9 100644 --- a/hw/char/escc.c +++ b/hw/char/escc.c @@ -574,7 +574,7 @@ static uint64_t escc_mem_read(void *opaque, hwaddr addr, static const MemoryRegionOps escc_mem_ops = { .read = escc_mem_read, .write = escc_mem_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_BIG_ENDIAN, .valid = { .min_access_size = 1, .max_access_size = 1, diff --git a/hw/char/etraxfs_ser.c b/hw/char/etraxfs_ser.c index 9745bca..cda687b 100644 --- a/hw/char/etraxfs_ser.c +++ b/hw/char/etraxfs_ser.c @@ -155,7 +155,7 @@ ser_write(void *opaque, hwaddr addr, static const MemoryRegionOps ser_ops = { .read = ser_read, .write = ser_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_LITTLE_ENDIAN, .valid = { .min_access_size = 4, .max_access_size = 4 diff --git a/hw/char/grlib_apbuart.c b/hw/char/grlib_apbuart.c index c2bb3ac..119fc84 100644 --- a/hw/char/grlib_apbuart.c +++ b/hw/char/grlib_apbuart.c @@ -237,7 +237,7 @@ static void grlib_apbuart_write(void *opaque, hwaddr addr, static const MemoryRegionOps grlib_apbuart_ops = { .write = grlib_apbuart_write, .read = grlib_apbuart_read, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_BIG_ENDIAN, }; static void grlib_apbuart_realize(DeviceState *dev, Error **errp) diff --git a/hw/char/imx_serial.c b/hw/char/imx_serial.c index 0655a95..7c66551 100644 --- a/hw/char/imx_serial.c +++ b/hw/char/imx_serial.c @@ -332,7 +332,7 @@ static void imx_event(void *opaque, int event) static const struct MemoryRegionOps imx_serial_ops = { .read = imx_serial_read, .write = imx_serial_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_LITTLE_ENDIAN, }; static void imx_serial_realize(DeviceState *dev, Error **errp) diff --git a/hw/char/lm32_uart.c b/hw/char/lm32_uart.c index d047a44..2fe5f60 100644 --- a/hw/char/lm32_uart.c +++ b/hw/char/lm32_uart.c @@ -205,7 +205,7 @@ static void uart_write(void *opaque, hwaddr addr, static const MemoryRegionOps uart_ops = { .read = uart_read, .write = uart_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_BIG_ENDIAN, .valid = { .min_access_size = 4, .max_access_size = 4, diff --git a/hw/char/milkymist-uart.c b/hw/char/milkymist-uart.c index 8a78fcc..bdb8282 100644 --- a/hw/char/milkymist-uart.c +++ b/hw/char/milkymist-uart.c @@ -156,7 +156,7 @@ static const MemoryRegionOps uart_mmio_ops = { .min_access_size = 4, .max_access_size = 4, }, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_BIG_ENDIAN, }; static void uart_rx(void *opaque, const uint8_t *buf, int size) diff --git a/hw/char/pl011.c b/hw/char/pl011.c index c1ae2f3..5fb95d2 100644 --- a/hw/char/pl011.c +++ b/hw/char/pl011.c @@ -287,7 +287,7 @@ static void pl011_event(void *opaque, int event) static const MemoryRegionOps pl011_ops = { .read = pl011_read, .write = pl011_write, - .endianness = DEVICE_NATIVE_ENDIAN, + .endianness = DEVICE_LITTLE_ENDIAN, }; static const VMStateDescription vmstate_pl011 = {
