b129eff5ed ppc4xx: Only fixup opb attached UARTs
This patch updates the fdt UART clock fixup code to
only touch CPU internal UARTs on 4xx systems.
Only these UARTs are definitely clocked by gd->uart_clk.

43cbce69d4 ppc4xx: Correctly setup ranges property in ebc node
Previously only the NOR flash mapping was written into the ranges
property of the ebc node. This patch now writes all enabled chip
select areas into the ranges property.

ba37aa0328 fdt: rework fdt_fixup_ethernet() to use env instead of bd_t
Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.

This makes the code a bit more flexible to the number of ethernet
interfaces.

e321801bed ppc4xx: Remove redundant ft_board_setup() functions from some 4xx boards
This patch removes some ft_board_setup() functions from some 4xx boards.
This can be done since we now have a default weak implementation for this
in cpu/ppc4xx/fdt.c. Only board in need for a different/custom
implementation like canyonlands need their own version.

cb5d88b961 ppc4xx: Add weak default ft_board_setup() routine
This patch adds a default ft_board_setup() routine to the 4xx fdt code.
This routine is defined as weak and can be overwritten by a board specific
one if needed.

eea5a743a2 ppc4xx: Fixup ebc clock in FDT for 405GP/EP
On ppc405EP and ppc405GP (at least) the ebc is directly attached to the plb
and not to the opb. This patch will try to fixup /plb/ebc if /plb/opb/ebc
doesn't exist.

24bfedbd0b ppc4xx: Pass PCIe root-complex/endpoint configuration to Linux via the fdt
The PCIe root-complex/endpoint setup as configured via the "pcie_mode"
environment variable will now get passed to the Linux kernel by setting
the device_type property of the PCIe device tree node. For normal root-
complex configuration it will keep its defaults value of "pci" and for
endpoint configuration it will get changed to "pci-endpoint".

328a340392 ppc4xx: fdt: Cleanup setup of cpu node setup
Now the cpu node setup ("timebase-frequency" and "clock-frequency") is
without using the absolute path to the cpu node. This makes it possible
to use this U-Boot version with both versions of cpu-node naming
"cpu@0" and the former "PowerPC,440EPx@0".

871e6ce188 ppc4xx: fdt: use fdt_fixup_ethernet()
By using aliases in the dts file, the ethernet node fixup is
much easier with the recently added functions.

Please note that the dts file needs the aliases for this to work.

136288847e ppc4xx: Bring 4xx fdt support up-to-date
This patch update the 4xx fdt support. It enabled fdt booting
on the AMCC Kilauea and Sequoia for now. More can follow later
quite easily.

f10493c6d7 ppc4xx: Correct UART input clock calculation and passing to fdt
We now use a value in the gd (global data) structure for the UART input
frequency, since the PPC4xx_SYS_INFO struct is always rewritten completely
in get_sys_info().
