[Qemu-ppc] [Qemu-devel] [PATCH v7 28/42] hw/sd: Declare device little or

Subject: [Qemu-ppc] [Qemu-devel] [PATCH v7 28/42] hw/sd: Declare device little or big endian
Date: Fri, 16 Aug 2019 07:35:32 +0000

For each device declared with DEVICE_NATIVE_ENDIAN, find the set of
targets from the set of target/hw/*/device.o.

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

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 =)
