The doc [1] doesn't define the endianness, but the kernel driver uses readl() to access the registers, so we can guess it depends on the architecture endianness. As riscv architecture endianness is little it might not change anything for it. Moreover, android implementation uses DEVICE_NATIVE_ENDIAN [2] [1] https://android.googlesource.com/platform/external/qemu/+/master/docs/GOLDFISH-VIRTUAL-HARDWARE.TXT [2] https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/hw/timer/goldfish_timer.c#177 Fixes: 9a5b40b84279 ("hw: rtc: Add Goldfish RTC device") Cc: Anup.Patel@wdc.com Signed-off-by: Laurent Vivier <lvivier@redhat.com> --- hw/rtc/goldfish_rtc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
