2008-03-26[POWERPC] Start removing linux,network-index in favour of aliasesDavid Gibson
This patch alters the bootwrapper for a number of machines (roubhly all 4xx based cuboot or treeboot platforms) to use aliases instead of the linux,network-index hack to work out which MAC address to attach to which ethernet device node. The now obsolete linux,network-index properties are removed from the corresponding device trees. This won't break backwards compatiblity, because in cases where this fixup code is relevant, the device tree is part of the kernel image. The references to linux,network-index are removed from booting-without-of.txt. Not only is it now deprecated, but as a hack applicable only when the device tree blob and fixup code were in the same image, this property never belonged in booting-without-of.txt which describes the interface between the kernel and firmware or bootloaders which produce a device tree. By the time the device tree reaches the kernel, all the MAC addresses must be fully filled in.

2008-02-27[POWERPC] 44x: add missing define TARGET_4xx and TARGET_440GX to cuboot-taishanValentine Barshak
In order to get the proper boad info (bd_info) structure defined in ppcboot.h both TARGET_4xx and TARGET_44x should be defined for all PowerPC 440 boards. The 440GX boards also need TARGET_440GX defined since they have 4 EMACs and there are 4 MAC addesses in bd_info passed by u-boot.

2007-12-23[POWERPC] 4xx: Rework clock probing in boot wrapperBenjamin Herrenschmidt
This reworks the boot wrapper library function that probes the chip clocks. Better separate the base function that is used on 440GX,SPe,EP,... from the uart fixups as those need different device-tree path on different processors. Also, rework the function itself based on the arch/ppc code from Eugene Surovegin which I find more readable, and which handles one more bypass case. Also handle the subtle difference between 440EP/EPx and 440SPe/GX, on the former, PerClk is derived from the PLB clock while on the later, it's derived from the OPB.
