      [POWERPC] Enable RTC for Ebony and Walnut (v2) · 22258fa4
      由 David Gibson 提交于 
      This patch extends the Ebony and Walnut platform code to instantiate
the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip
found on both those boards.  The patch uses a helper function to scan
the device tree and instantiate the appropriate platform_device based
on it, so it should be easy to extend for other boards which have mmio
mapped RTC chips.

Along with this, the device tree binding for the ds1743 chips is
tweaked, based on the existing DS1385 OF binding found at:
	http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt
Although that document covers the NVRAM portion of the chip, whereas
here we're interested in the RTC portion, so it's not entirely clear
if that's a good model.

This implements only RTC class driver support - that is /dev/rtc0, not
/dev/rtc, and the low-level get/set time callbacks remain
unimplemented.  That means in order to get at the clock you will
either need a modified version of hwclock which will look at
/dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

      Device tree aware EMAC driver · 1d3bb996
      由 David Gibson 提交于 
      Based on BenH's earlier work, this is a new version of the EMAC driver
for the built-in ethernet found on PowerPC 4xx embedded CPUs.  The
same ASIC is also found in the Axon bridge chip.  This new version is
designed to work in the arch/powerpc tree, using the device tree to
probe the device, rather than the old and ugly arch/ppc OCP layer.

This driver is designed to sit alongside the old driver (that lies in
drivers/net/ibm_emac and this one in drivers/net/ibm_newemac).  The
old driver is left in place to support arch/ppc until arch/ppc itself
reaches its final demise (not too long now, with luck).

This driver still has a number of things that could do with cleaning
up, but I think they can be fixed up after merging.  Specifically:
	- Should be adjusted to properly use the dma mapping API.
Axon needs this.
	- Probe logic needs reworking, in conjuction with the general
probing code for of_platform devices.  The dependencies here between
EMAC, MAL, ZMII etc. make this complicated.  At present, it usually
works, because we initialize and register the sub-drivers before the
EMAC driver itself, and (being in driver code) runs after the devices
themselves have been instantiated from the device tree.

      [POWERPC] Small fixes for the Ebony device tree · c72ea777
      由 David Gibson 提交于 
      This patch corrects a number of minor errors in the Ebony device tree:
	- Missing (given as 0) cache sizes are added to the CPU node
	- device_type properties are removed from nodes which don't
have a reasonably well defined device_type binding.  This does require
a very small code change to locate the busses to be probed for
of_platform devices by 'compatible' instead of 'device_type'.
	- A node is added for the SRAM controller
	- The unit address of the small-flash node is adjusted to
correctly reflect the reg property.
	- device_type values for the MAL and ZMII are updated to
reflected more up-to-date versions of the binding.
	- An incorrect offset in the partition map for the large-flash
node is corrected.
	- Some redundant values, already commented out are removed
entirely.

      [POWERPC] Fix Kconfig undefined symbol 'IBM_NEW_EMAC_ZMII' · e38e3458

      An allmodconfig on the current powerpc tree yields:
arch/powerpc/platforms/44x/Kconfig:41:warning: 'select' used by
config symbol '440GP' refers to undefined symbol 'IBM_NEW_EMAC_ZMII'

Hide the select until the driver exists.
