[PATCH 0/2] MIPS: SiByte: Update SWARM defconfig for PATA support

[Maciej W. Rozycki]

Hi,

 In the course of looking into Christoph's recent proposal to drop legacy 
IDE drivers I have noticed that SiByte SWARM's defconfig does not enable 
the pata_platform driver for the onboard PATA interface.  I think default 
configuration ought to enable all the supported onboard devices unless 
there are specific reasons so as not to, and the PATA interface is one of 
the boot devices supported by the CFE firmware, so I think even more then 
that it should be included by default.

 Change split into two because the defconfig has become stale since the 
last update, so 1/2 first regenerates it, and then 2/2 applies the actual 
modification.

 Sadly I'm currently away from my SWARM board for the foreseeable future 
and I have no remote access to it either, but this is supposed not to need 
run-time verification.  Build-tested only then.

 Please apply.

  Maciej

[PATCH 1/2] MIPS: SiByte: Regenerate stale SWARM defconfig

[Maciej W. Rozycki]

Options have been removed and reordered since the last update, so 
regenerate the template so as not to interfere with actual changes.

[PATCH 2/2] MIPS: SiByte: Enable pata_platform with SWARM defconfig

[Maciej W. Rozycki]

Enable support for the onboard PATA PIO mode3 interface, which is one of 
the boot devices supported by the CFE firmware with the Broadcom SWARM 
board.  Include disk, CD-ROM and generic storage drivers.

series applied to mips-next.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
