From: Michal Simek <michal.simek@xilinx.com>
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 cdeb89943bfc ("MAINTAINERS: Fix incorrect status tag") and
commit 19624236cce1 ("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>;

- 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:
-

- END
-

- PARAMETER HW_VER = 1.02.a

- 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 C_RNG0_BASEADDR = 0x20000000

- 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):

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

- * software control. In addition, the instruction side has a
- * hardware-managed, 4-entry, fully-associative TLB which serves as a
- * first level to the shared TLB. These two TLBs are known as the UTLB
- * and ITLB, respectively (see "mmu.h" for definitions).
- *
- * There are several potential gotchas here. The 40x hardware TLBLO
- * field looks like this:
- *
- * 0 1 2 3 4 ... 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- * RPN..................... 0 0 EX WR ZSEL....... W I M G
- *
- * Where possible we make the Linux PTE bits match up with this
- *
- * - bits 20 and 21 must be cleared, because we use 4k pages (40x can
- * support down to 1k pages), this is done in the TLBMiss exception
- * handler.
- * - We use only zones 0 (for kernel pages) and 1 (for user pages)
- * of the 16 available. Bit 24-26 of the TLB are cleared in the TLB
- * miss handler. Bit 27 is PAGE_USER, thus selecting the correct
- * zone.
- * - PRESENT *must* be in the bottom two bits because swap cache
- * entries use the top 30 bits. Because 40x doesn't support SMP
- * anyway, M is irrelevant so we borrow it for PAGE_PRESENT. Bit 30
- * is cleared in the TLB miss handler before the TLB entry is loaded.
- * - All other bits of the PTE are loaded into TLBLO without
- * modification, leaving us only the bits 20, 21, 24, 25, 26, 30 for
- * software PTE bits. We actually use bits 21, 24, 25, and
- * 30 respectively for the software bits: ACCESSED, DIRTY, RW, and
- * PRESENT.

This erratum is dedicated to IBM405 which was part of 40x platforms.
Now that 40x platforms are gone, this erratum can be removed.

xmon has special support for PPC403 and PPC405 which were part
of 40x platforms.
40x platforms are gone, remove support of PPC403 and PPC405 in xmon.

CONFIG_4xx was corresponding to CONFIG_40x | CONFIG_44x.
As CONFIG_40x is gone, CONFIG_4xx and CONFIG_44x are now equivalent.
And CONFIG_BOOKE is also set when CONFIG_44x is set.
Replace (CONFIG_4xx | CONFIG_BOOKE) by CONFIG_BOOKE
Replace other CONFIG_4xx by CONFIG_44x
Remove CONFIG_4xx.

RFI was a macro waving the rfi instruction for the 40x.
Now that 40x is gone, rfi can be used directly.

These files are from binutils, and may get synchronized with changes there
in the future. I'd suggest leaving the code in here for now and instead removing
it from the binutils version first, if they are ready to drop it, too.

No objections to moving everything into one place, but I wonder if the
combined name should be 4xx instead of 44x, given that 44x currently
include 46x and 47x. OTOH your approach has the advantage of
moving fewer files.

In that case, should we also rename CONFIG_44x to CONFIG_4xx ?

That has the risk of breaking user's defconfig files, but given the
small number of users, it may be nicer for consistency. In either
case, the two symbols should probably hang around as synonyms,
the question is just which one is user visible.

Not sure it is a good idea to keep two synonyms. In the past we made our
best to remove synonyms (We had CONFIG_8xx and CONFIG_PPC_8xx being
synonyms, we had CONFIG_6xx and CONFIG_BOOK3S_32 and
CONFIG_PPC_STD_MMU_32 being synonyms).
I think it is a lot cleaner when we can avoid synonyms.
By the way I already dropped CONFIG_4xx in previous patch (8/11). It was
not many 4xx changed to 44x. It would be a lot more in the other way
round I'm afraid.
But I agree with you it might be more natural to change to 4xx.
Michael, any preference ?

Ok, fair enough.

Right. Maybe stay with 44x for both then (as in your current patches), as it
means changing less in a part of the code that has few users anyway.

Yes those files are almost direct copies of the binutils versions, and
we'd like to keep it that way to ease future synchronisation of changes.

I'd say just use 44x, we've had the inconsistency of 476 living in
platforms/44x, and it hasn't really led to much confusion.
I think for most folks they see 4xx/44x and just think "some 32-bit
embedded thing", so the precise distinction between 4xx, 44x, 476 etc.
is not that important to justify renaming the symbol everywhere I think.
