Subject: [PATCH 0/5 v4] Fixes for running a big-endian kernel on Cubieboard2
Date: Mon, 22 Aug 2016 18:42:14 +0200 [thread overview]
Message-ID: <20160822164219.14272-1-michael.weiser@gmx.de> (raw)
Hello,
the following patches allow to run a big-endian kernel on the
Cubieboard2.
The first two patches fix up endianness problems with DMA descriptors in
the sunxi-mmc and stmmac drivers preventing them from working correctly
when runnning a big-endian kernel.
The third patch adds the ability to enable diagnostic messages in the
sun4i-emac driver which were instrumental in finding the problem fixed
by patch number four: Endianness confusion caused by dual-purpose I/O
register usage in sun4i-emac.
The final patch enables the big-endian kernel configuration option for
sun7i devices in order to be able to compile a big-endian kernel for the
Cubieboard2.
All of these have been tested successfull on a Cubieboard2 DualCard.
Changes since v3:
- Rebased sunxi-mmc patch against Ulf's mmc.git/next
- Changed Kconfig change to enable big-endian support only for sun7i
devices
Changes since v2:
- Fixed typo in stmmac patch causing a build failure
- Added sun4i-emac patches
Changes since v1:
- Fixed checkpatch niggles
- Added respective Cc:s
Regards,
Michael
