powerpc: Remove Xilinx PPC405/PPC440 support

Browse Source 
The latest Xilinx design tools called ISE and EDK has been released in
October 2013. New tool doesn't support any PPC405/PPC440 new designs.
These platforms are no longer supported and tested.

PowerPC 405/440 port is orphan from 2013 by
commit cdeb89943b ("MAINTAINERS: Fix incorrect status tag") and
commit 19624236cc ("MAINTAINERS: Update Grant's email address and maintainership")
that's why it is time to remove the support fot these platforms.

Some IP cores actually implement 2 or more logical devices. In
this case, the device should still describe the whole IP core with
a single node and add a child node for each logical device. The
ranges property can be used to translate from parent IP-core to the
registers of each device. In addition, the parent node should be
compatible with the bus type 'xlnx,compound', and should contain
#address-cells and #size-cells, as with any other bus. (Note: this
makes the assumption that both logical devices have the same bus
binding. If this is not true, then separate nodes should be used
for each logical device). The 'cell-index' property can be used to
enumerate logical devices within an IP core. For example, the
following is the system.mhs entry for the dual ps2 controller found
on the ml403 reference design.
BEGIN opb_ps2_dual_ref
PARAMETER INSTANCE = opb_ps2_dual_ref_0
PARAMETER HW_VER = 1.00.a
PARAMETER C_BASEADDR = 0xA9000000
PARAMETER C_HIGHADDR = 0xA9001FFF
BUS_INTERFACE SOPB = opb_v20_0
PORT Sys_Intr1 = ps2_1_intr
PORT Sys_Intr2 = ps2_2_intr
PORT Clkin1 = ps2_clk_rx_1
PORT Clkin2 = ps2_clk_rx_2
PORT Clkpd1 = ps2_clk_tx_1
PORT Clkpd2 = ps2_clk_tx_2
PORT Rx1 = ps2_d_rx_1
PORT Rx2 = ps2_d_rx_2
PORT Txpd1 = ps2_d_tx_1
PORT Txpd2 = ps2_d_tx_2
END
It would result in the following device tree nodes:
opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "xlnx,compound";
ranges = <0 a9000000 2000>;
// If this device had extra parameters, then they would
// go here.
ps2@0 {
compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
reg = <0 40>;
interrupt-parent = <&opb_intc_0>;
interrupts = <3 0>;
cell-index = <0>;
};
ps2@1000 {
compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
reg = <1000 40>;
interrupt-parent = <&opb_intc_0>;
interrupts = <3 0>;
cell-index = <0>;
};
};
Also, the system.mhs file defines bus attachments from the processor
to the devices. The device tree structure should reflect the bus
attachments. Again an example; this system.mhs fragment:
BEGIN ppc405_virtex4
PARAMETER INSTANCE = ppc405_0
PARAMETER HW_VER = 1.01.a
BUS_INTERFACE DPLB = plb_v34_0
BUS_INTERFACE IPLB = plb_v34_0
END
BEGIN opb_intc
PARAMETER INSTANCE = opb_intc_0
PARAMETER HW_VER = 1.00.c
PARAMETER C_BASEADDR = 0xD1000FC0
PARAMETER C_HIGHADDR = 0xD1000FDF
BUS_INTERFACE SOPB = opb_v20_0
END
BEGIN opb_uart16550
PARAMETER INSTANCE = opb_uart16550_0
PARAMETER HW_VER = 1.00.d
PARAMETER C_BASEADDR = 0xa0000000
PARAMETER C_HIGHADDR = 0xa0001FFF
BUS_INTERFACE SOPB = opb_v20_0
END
BEGIN plb_v34
PARAMETER INSTANCE = plb_v34_0
PARAMETER HW_VER = 1.02.a
END
BEGIN plb_bram_if_cntlr
PARAMETER INSTANCE = plb_bram_if_cntlr_0
PARAMETER HW_VER = 1.00.b
PARAMETER C_BASEADDR = 0xFFFF0000
PARAMETER C_HIGHADDR = 0xFFFFFFFF
BUS_INTERFACE SPLB = plb_v34_0
END
BEGIN plb2opb_bridge
PARAMETER INSTANCE = plb2opb_bridge_0
PARAMETER HW_VER = 1.01.a
PARAMETER C_RNG0_BASEADDR = 0x20000000
PARAMETER C_RNG0_HIGHADDR = 0x3FFFFFFF
PARAMETER C_RNG1_BASEADDR = 0x60000000
PARAMETER C_RNG1_HIGHADDR = 0x7FFFFFFF
PARAMETER C_RNG2_BASEADDR = 0x80000000
PARAMETER C_RNG2_HIGHADDR = 0xBFFFFFFF
PARAMETER C_RNG3_BASEADDR = 0xC0000000
PARAMETER C_RNG3_HIGHADDR = 0xDFFFFFFF
BUS_INTERFACE SPLB = plb_v34_0
BUS_INTERFACE MOPB = opb_v20_0
END
Gives this device tree (some properties removed for clarity):
plb@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "xlnx,plb-v34-1.02.a";
device_type = "ibm,plb";
ranges; // 1:1 translation
plb_bram_if_cntrl_0: bram@ffff0000 {
reg = <ffff0000 10000>;
}
opb@20000000 {
#address-cells = <1>;
#size-cells = <1>;
ranges = <20000000 20000000 20000000
60000000 60000000 20000000
80000000 80000000 40000000
c0000000 c0000000 20000000>;
opb_uart16550_0: serial@a0000000 {
reg = <a00000000 2000>;
};
opb_intc_0: interrupt-controller@d1000fc0 {
reg = <d1000fc0 20>;

};
};
That covers the general approach to binding xilinx IP cores into the
device tree. The following are bindings for specific devices:

kernel with this image type and it depends entirely on
the embedded device tree for all information.
The simpleImage is useful for booting systems with
an unknown firmware interface or for booting from
a debugger when no firmware is present (such as on
the Xilinx Virtex platform). The only assumption that
simpleImage makes is that RAM is correctly initialized
and that the MMU is either off or has RAM mapped to
base address 0.
simpleImage also supports inserting special platform
specific initialization code to the start of the bootup
sequence. The virtex405 platform uses this feature to
ensure that the cache is invalidated before caching
is enabled. Platform specific initialization code is
added as part of the wrapper script and is keyed on
the image target name. For example, all
simpleImage.virtex405-* targets will add the
virtex405-head.S initialization code (This also means
that the dts file for virtex405 targets should be
named (virtex405-<board>.dts). Search the wrapper
script for 'virtex405' and see the file
arch/powerpc/boot/virtex405-head.S for details.

tree source based on the name of the target. Therefore, if the kernel is
built with 'make treeImage.walnut simpleImage.virtex405-ml403', then the
