Agreed, we should define CONFIG_E500 as internal and used for common =
functionality between E500, E500MC, E5500, E6500.

I hope that is not true, as the template is the same.
BOARD.dts:
include "fsl/SOCsi-pre.dtsi"
=85
include "fsl/SOCsi-post.dtsi"
[ some boards may do more complicated things like we do on MPC8572DS to =
deal with 32-bit vs 36-bit addr maps, or CAMP use examples ]
All BOARD dts's should follow this pattern given the knowledge of which =

Nope, we can have as many boards for the same SoC w/different address =

We utilize two 'features' of dtc to accomplish things. One is includes =
the other is 'merging of labeled nodes'.
We can using merging to allow the board to specify the "reg" & "ranges" =
values of a SoC node that might vary between physical address maps =
(32-bit vs 36-bit as example).
dtc is able to 'merge' multiple labeled nodes as well. So we use that =
to handle board specific values for something like localbus if we want =
to support both a 32-bit and 36-bit address map.

I understand the value of removing duplication of DTS contents, so
that we don't copy-paste the same nodes over and over again, but now
that you've added pre- and post- dtsi files, I wonder if you're not
jumping out of the frying pan and into the flame. It seems that the
DTS files are more fragile than ever, and it's more difficult now to
figure out which files go where.
Another concern I have is whether this will force all Pxxxx boards to
have the same CCSR address. I don't think so, because I didn't see
it, but I just want to make sure.

Well, a kernel built with CONFIG_PPC_E500MC today appears to be
fundamentally broken on E500v1/E500v2:
#if defined(CONFIG_8xx) || defined(CONFIG_403GCX)
#define L1_CACHE_SHIFT 4
#define MAX_COPY_PREFETCH 1
#elif defined(CONFIG_PPC_E500MC)
#define L1_CACHE_SHIFT 6
#define MAX_COPY_PREFETCH 4
#elif defined(CONFIG_PPC32)
#define MAX_COPY_PREFETCH 4
#if defined(CONFIG_PPC_47x)
#define L1_CACHE_SHIFT 7
#else
#define L1_CACHE_SHIFT 5
#endif
#else /* CONFIG_PPC64 */
#define L1_CACHE_SHIFT 7
#endif
E500MC will set L1_CACHE_SHIFT to 6, while regular E500 appears to
want it set to 5. I don't know if that's a mistake or exactly what
code that affects, but it looks very wrong.
Furthermore, it looks like there are a couple issues here I missed
before. PPC64 systems all appear to have an L1_CACHE_SHIFT of 7,
except when you turn on the P5020DS board option which magically
changes it to "6" and breaks lord-knows-what. I think my patch
series actually "breaks" that and makes e5500 use 7 as well.
Are you sure that a kernel built to support E5500 can also run on
other 64-bit PowerPC/POWER systems?

It's actually a bit more complicated than that. There are 3 ways
that the user can configure an e500 kernel today. I'm omitting
the "FSL_SOC_BOOKE" menu that wraps around all of the 85xx/e5500
boards today, because that is set for all of these platforms:
* PPC32 + PPC_85xx + E500 [+ boards]
* PPC64 + BOOK3E_64 + P5020_DS (which adds E500 and PPC_E500MC)
Note that whether or not "PPC_E500MC" is set on PPC32 depends
only on which boards the user picked. So if I am trying to
build an e500v2 kernel and I accidentally also turn on support
for one of the e500mc boards, my kernel mysteriously breaks.

> I see no reason to hyper-optimize e500mc vs e5500 vs e6500.
So after my changes, there are the following user-configurable
option sets:
* PPC32 + FSL_E500_V1_V2 [+ e500v1/v2 boards]
* PPC32 + FSL_E500MC [+ e500mc boards]
* PPC64 + BOOK3E_64 + P5020_DS (which adds FSL_E5500)
Since most of the "e500mc"-specific code was in 32-bit-only ASM
or inside of #ifdef PPC32, the new FSL_E500MC option is only
set on 32-bit builds, even if it is running in compat mode on
64-bit e5500 hardware)
Internally the P5020_DS option turns on the hidden FSL_E5500
option for both 32-bit and 64-bit; that config option enables
platform drivers and similar stuff.
Depending on how compatible the AMP processors are, you could
rename the option to be "FSL_E5X00" or add a hidden option for
"FSL_E6500" that is also selected by appropriate boards.
Please let me know if you think!
Cheers,
Kyle Moffett

For running legacy software, or for multiplatform Linux kernels?
And if you're willing to toss performance away for this goal, why do you
need lwsync? :-)
DCBZ32 is not a "mode that is compatible with v1/v2", BTW. It only
affects cache block size (for dcbz/dcba only), not SPE versus FP, not
changes in power management, not changes in machine check handling, etc.
Using DCBZ32 for the kernel would also complicate switching the kernel to
dcbzl, to support enabling DCBZ32 for certain userspace apps (a more
likely use case) without making it systemwide.

I never understood why we have PHYS_64BIT and ARCH_PHYS_ADDR_T_64BIT, since they mean the same thing.

I posted a patch to remove the P1022_DS version of this. I'm in favor of removing it from the other boards and letting the defconfig define it, but Kumar nak'd that idea.

I think this one is about how our TLB registers look, and it's not related to anything else.

There's a Kconfig option somewhere that takes care of this.

I'm not sure that Kconfig rule is enforceable. We use 'select' all the time to make sure that our boards enable the options that need to be enabled. I'd rather see this:
config X
select A
config Y
select A
config Z
select A
than this:
config A
default y if X | Y | Z
The former is more maintainable and does not allow the option of disabling "A" if someone wants "X".

They're really 64-bit DTS addresses. The 36 bit is just a hardware quirk of our SOCs. From the kernel's perspective, there's no difference between 36-bit and 64-bit physical address.

Because Kumar doesn't want to allow 32-bit kernels on our high-end parts. Like I said, I'm not a fan of that decision.

It's just an arbitrary decision. We don't ship 32-bit DTs for the P4080-class parts, and we don't have a U-Boot configuration option for building a 32-bit compatible U-Boot.

How much code is this? e5500 is basically just a 64-bit version of
e500mc. When running a 32-bit kernel the extra code should be minimal.

Did you look at the existing code? It's already that complicated:
config ARCH_PHYS_ADDR_T_64BIT
def_bool PPC64 || PHYS_64BIT
config ARCH_DMA_ADDR_T_64BIT
def_bool ARCH_PHYS_ADDR_T_64BIT
config {P1022_DS,P2041_RDB,P3041_DS,P3060_QDS,P4080_DS,P5020_DS}
select PHYS_64BIT
config 44x
select PHYS_64BIT
config PTE_64BIT
bool
depends on 44x || E500 || PPC_86xx
default y if PHYS_64BIT
config PHYS_64BIT
bool 'Large physical address support' if E500 || PPC_86xx
depends on (44x || E500 || PPC_86xx) && !PPC_83xx && !PPC_82xx
Even worse, PHYS_64BIT is not set on 64-bit processors, but there is
a lot of driver code that seems to assume PHYS_64BIT indicates the
size of "phys_addr_t".

The big issue is that the Kconfig docs are very clear that "select"
should not be used on user-visible options (AKA: PHYS_64BIT), and yet
half the PPC_85xx boards have this tidbit:
select PHYS_64BIT # The DTS has 36-bit addresses
I'm totally OK with removing that from all those boards, but to preserve
the existing behavior (also used by the entire 44x platform) I added the
new config symbol PHYS_64BIT_DT_REQUIRED, which is used to control
whether or not the "PHYS_64BIT" option is even visible to the user.
I originally called it "PHYS_64BIT_REQUIRED", but since all of the
board comments talked about 36-bit DTS addresses, I added the _DT_.

If this is true, then why does PHYS_64BIT have that big ugly list of
dependencies right now? I don't know about the other platforms well
enough to tell what would break by enabling PHYS_64BIT, but I assume
that something in the past caused that dependency list.

What "mode" do you mean? DCBZ32? We don't support using that currently,
and I'd imagine the performance implication would be such that you'd
never want to do it unless it's the only way to make some piece of legacy
software work.

This is correct for E500 & E500MC. However we have a HW mode that =

a value of '6' on E5500 / P5020DS is correct and doesn't break anything. =
Setting it to 7 is wrong and thus the code is correct today.

No it will not. There is not expectation of that as E5500 is an =

I'd like to avoid adding FSL_E5500, FSL_E6500, etc CONFIG options =
getting added. I'd like to keep things as:
32-bit:
e500v1/v2
e500mc/e5500/e6500/...
64-bit:
e5500/e6500/...
We need to come up with some CONFIG option that covers =
e500mc/e5500/e6500/...
