powerpc, 8260: remove support for mpc8260

Browse Source 
There was for long time no activity in the 8260 area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 8260,
so remove it.

* Hard Reset Configuration Word (HRCW) table
*
* The Hard Reset Configuration Word (HRCW) sets a number of useful things
* such as whether there is an external memory controller, whether the
* PowerPC core is disabled (i.e. only the communications processor is
* active, accessed by another CPU on the bus), whether using external
* arbitration, external bus mode, boot port size, core initial prefix,
* internal space base, boot memory space, etc.
*
* These things dictate where the processor begins execution, where the
* boot ROM appears in memory, the memory controller setup when access
* boot ROM, etc. The HRCW is *extremely* important.
*
* The HRCW is read from the bus during reset. One CPU on the bus will
* be a hard reset configuration master, any others will be hard reset
* configuration slaves. The master reads eight HRCWs from flash during
* reset - the first it uses for itself, the other 7 it communicates to
* up to 7 configuration slaves by some complicated mechanism, which is
* not really important here.
*
* The configuration master performs 32 successive reads starting at address
* 0 and incrementing by 8 each read (i.e. on 64 bit boundaries) but only 8
* bits is read, and always from byte lane D[0-7] (so that port size of the
* boot device does not matter). The first four reads form the 32 bit HRCW
* for the master itself. The second four reads form the HRCW for the first
* slave, and so on, up to seven slaves. The 32 bit HRCW is formed by
* concatenating the four bytes, with the first read placed in byte 0 (the
* most significant byte), and so on with the fourth read placed in byte 3
* (the least significant byte).

* is 0xfff00000. In the case of a Power On Reset or Hard Reset, the value

*
* Other bits in the HRCW set up the Base Address and Port Size in BR0.

* so that we eventually end up executing the code below when the processor
* executes the reset exception, the actual values used should not matter.
*
* Once we have got here, the address mask in OR0 is cleared so that the
* bottom 32K of the boot ROM is effectively repeated all throughout the
* processor's address space, after which we can jump to the absolute
* address at which the boot ROM was linked at compile time, and proceed
* to initialise the memory controller without worrying if the rug will be
* pulled out from under us, so to speak (it will be fine as long as we
* configure BR0 with the same boot ROM link address).

Attached is an IDMA example code for MPC8260/PPCBoot. I had tried to
search around and could not find any for implementing IDMA, so
implemented one. Its not coded in the best way, but works.
Also, I was able to test the IDMA specific code under Linux also
(with modifications). My requirement was to implement it for
CompactFlash implemented in memory mode, and it works for it under
PPCBoot and Linux.
