[U-Boot] [PATCH 3/3 V2] dm9000: rework dm9000 to support multiple devices
Andrew Ruder

Mon Oct 20 20:11:48 CEST 2014
The DM9000 was hard-coded to only support one DM9000 device. This patch
adds a new initialization function - dm9000_initialize_ex() - to support
registering multiple (and possibly dynamic) numbers of dm9000 devices.
This patch consists of:
* Change the board_info struct to a private struct under eth_device.
* Add io address/data address/srom availability information to this
private struct.
* Replace all uses of DM9000_IO/DM9000_DATA with new members, ensure
that the eth_device struct propagates down to all helper functions.
* Make dm9000_initialize() call dm9000_initialize_ex() with filled
in information from the old preprocessor symbols (DM9000_IO,
DM9000_DATA, etc.)
Overall the following parameters have been moved over to being a
per-chip setting:
DM9000_IO, DM9000_DATA, CONFIG_DM9000_NO_SROM
while the following is still a global setting affecting all chips:
CONFIG_DM9000_BYTE_SWAPPED
And the following has been removed entirely:
CONFIG_DM9000_BASE (was only used in a single printf)

Maybe a useful exercise anyway, this patch is significantly more messy with all
the whitespace cleanups. See the v1 for the changes without the noise. :)
