Subject: [Qemu-devel] [RFC PATCH 07/17] hw/i2c: Declare device little or big endian
Date: Sat, 24 Aug 2019 04:56:28 +1000 [thread overview]
Message-ID: <90bd564769dbabaa7cf70b08e77170d54fa4b625.1566467963.git.tony.nguyen@bt.com> (raw)
In-Reply-To: <cover.1566467963.git.tony.nguyen@bt.com>
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
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 =)
