Added support for the D-Link DSM-G600 RevA, and fixed the clock frequency for NSLU2 and DSMG600. Had to refresh the gateway 7001 patch due to changes in the file being patched.

This patch adds support for the D-Link DSM-G600 Rev A.
|
||||||
|
This is an ARM XScale IXP4xx system relatively similar to
|
||||||
|
the NSLU2 and NAS-100D already supported by mainline. An
|
||||||
|
important difference is Gigabit Ethernet support using
|
||||||
|
the Via Velocity chipset.
|
||||||
|
|
||||||
|
This patch is the combined work of Michael Westerhof and
|
||||||
|
Alessandro Zummo, with contributions from Michael-Luke
|
||||||
|
Jones. This version addresses review comments from rmk
|
||||||
|
and Deepak Saxena.

This patch is required as the frequency fixup in nslu2_init does not
|
||||||
|
run sufficiently early in the boot sequence to take effect. In
|
||||||
|
addition the dsmg600 setup code behaviour has been improved such
|

|
that a 'fixup' routine is avoided.
