[POWERPC] 4xx bootwrapper reworks Make the fixup_memsize function common for all of 4xx as several chips share the same SDRAM controller. Also add functions to reset 40x chips and quiesce the ethernet. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

[POWERPC] 4xx: Adds decoding of 440SPE memory size to boot wrapper library This adds a function to the bootwrapper 4xx library to decode memory size on 440SPE processors. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

[POWERPC] 4xx: Rework clock probing in boot wrapper 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.

void ibm405gp_fixup_clocks(unsigned int sys_clk, unsigned int ser_clk);
[POWERPC] 4xx: Add 405GPr and 405EP support in boot wrapper This patch adds support for 405GPr processors with optional new mode strapping. ibm405gp_fixup_clocks() can now be used for 405GP and 405GPr CPUs. This is in preparation of porting the cpci405 platform support from arch/ppc to arch/powerpc. This patch also adds ibm405ep_fixup_clocks() to support 405EP CPUs from the boot wrapper.

powerpc/405ex: provide necessary fixup function to support cuImage For cuImage format it's necessary to provide clock fixups since u-boot will not pass necessary clock frequency into the dtb included into cuImage so we implement the clock fixups as defined in the technical documentation for the board and update header file with the basic register definitions.
