If we take the liberty to use register r0 to perform our bit set, we
should be nice enough to tell the compiler about it.
Add r0 to the clobber list to avoid potential mayhem.

Instead of enumerating all SoC families that need that bit set, let's
just express this more clearly: The SMP bits needs to be set on
SMP capable ARMv7 CPUs. It's much easier to Kconfig to express it the
other way round, so we use ! NO_SMP and ! ARM64.

Even for the single core cortex-a7, SMP bit should be set before
enabling MMU and cache.
Reference: Cortex A7 r0p5 TRM. section 4.3.31.

Ah, good point, thanks for the heads up. I was misled by the SMP name
when answering Icenowy.
So it's about coherency in general and we need the bit for TLBs and
caches to work as well.
Let me check what that means for the other SoCs and whether we need to
rename the config symbol then.
Cheers,
Andre.

If we still needs it, x86 has a CONFIG_SMP symbol, that would be
better to just leverage that.

So I checked the other ARMv7 Cortex TRMs, in contrast to the A7 TRM they
explicitly speak of cache and TLB requests from other _processors_.
So it should not be needed to use caches and the MMU on a uni-core
implementation (which seem to be pretty rare with Cortex-A7s).
But: my understanding is that it actually controls handling coherency
request from outside of the processor core, which could be from a
coherent agent on the bus as well, if I get this correctly.
So I think it does not hurt to enable the bit on the V3s as well and
could avoid potential problems. As this lines up with what the TRM says,
we should turn it on as in the other cores.
Icenowy: did you see problems with setting this bit and turned it off
for a reason or was that just because the bit is named "SMP"?
> If we still needs it,
First: we definitely need this symbol, since it guards an implementation
defined register and the Cortex-A53 does not define it. So we have to
confine its use to the ARMv7 Cortex CPUs.
> x86 has a CONFIG_SMP symbol, that would be

Sounds tempting, but this seems to be a generic symbol that enables SMP
support _within_ U-Boot, so it allows multiple cores to execute U-Boot
code. This is clearly not what we want. Defining it seems to enable
architecture specific and generic code paths in U-Boot.
I can rename this symbol if that helps to avoid confusion, for instance
to read CONFIG_SUNXI_NO_ACTLR_SMP or to CONFIG_CPU_IS_NOT_SMP or
CONFIG_CPU_IS_UP.
Cheers,
Andre.

There's nothing sunxi specific about it, the last one is better imho.

Well, I had the V3s in mind already, so it should be as easy as adding:
select SUNXI_NO_SMP
to your MACH_SUN8I_V3S stanza in board/sunxi/Kconfig, actually saving
you to alter the actual code #ifdefs.
Or am I missing something?

Andre.

For some reason we were pretty conservative when defining the maximum
SPL size for the Allwinner A80(sun9i) SoC.
According to the manual the SRAM A1 is even 40KB, but the BROM
probably still has the 32 KiB load limit. For the sake of simplicity,
merge the SPL memory definitions for the A64 and A80 SoCs, since both
SoC share the BROM/SRAM A1 memory layout.
This helps to further simplify this in the next patch.

Traditionally Allwinner SoCs have their boot ROM mapped just below 4GB,
while the first SRAM region is mapped at address 0.
With the extended physical memory support of the A80 this was changed,
so the BROM is now at address 0 and the SRAM region starts right behind
this at 64KB. This configuration seems to be called "high SRAM".
Instead of enumerating the SoCs which have copied this configuration,
let's call a spade a spade and introduce a Kconfig option for this setup.
SoCs implementing this (A80, A64 and H5, so far), can then select this
configuration.
Simplify the config header definition on the way.

Every armv8 board needs the memory map, so change the #ifdef to
ARM64 to avoid enumerating every single board or SoC.

Addresses passed on to readl and writel are expected to be of the same
size as a pointer. Change the parameter types of sunxi_spi0_read_data()
to make the compiler happy and allow a warning-free aarch64 compile.

How about using intptr_t and uintptr_t from include/compiler.h? It will make
it clearer that these parameters should be able to hold a pointer.

We normally use ulong for addresses in U-Boot.

The DRAM controller in the Allwinner H5 SoC is again very similar to
the one in the H3 and A64.
Based on the existing socid parameter, add support for this controller
by reusing the bulk of the code and only deviating where needed.
Also add the delay line parameters taken from the boot0 and libdram
disassembly.
Register setup differences between H5 and H3 are courtesy of Jens Kuske.

From: Andre Przywara @ 2017-01-13 1:30 UTC (permalink / raw)
To: u-boot
The Allwinner H5 is very close to the H3 SoC, but has ARMv8 cores.
To allow sharing the clocks, GPIO and driver code easily, create an
architecture agnostic MACH_SUN8I_H3_H5 Kconfig symbol.
Rename the existing symbol to MACH_SUN8I_H3_H5 where code is shared and
let it be selected by a new shared Kconfig option.

This isn't really related to sun8i anymore, how about
MACH_SUNXI_H3_H5?

This looks unrelated to your patch.

Ah, thanks for spotting this. It was an attempt to get rid of some
#ifdef's at all (by using a weak function), but I think I can just drop
it in this patch to keep the patch smaller and confined to one purpose.
Cheers,
Andre.

For the arch timer to work properly, we need to setup the CNTFRQ
register, which is only possible in EL3.
Define the arch timer frequency in sun8i.h as well, so that ARMv8's
start.S can program the register correctly.

Why not convert the armv8 code to use CONFIG_TIMER_CLK_FREQ, or armv7
to use COUNTER_FREQUENCY?
The both options seem redundant.

Good point, they indeed are.
So I will drop this patch here and instead have a new one to rename the
v7 users over to use COUNTER_FREQUENCY.
I chose COUNTER_FREQUENCY because the other symbol has less users.
Thanks for the idea!
Cheers,
Andre.

The Allwinner H5 Soc is bascially an H3 with high SRAM and ARMv8 cores.
As the peripherals and the pinmuxing are almost identical, we piggy
back on the shared MACH_SUN8I_H3_H5 config symbol.

The OrangePi PC 2 is a typical SBC with the 64-bit Allwinner H5 SoC.
Create a new .dts file for it by including the (32-bit) H3 SoC .dtsi
and changing the differing components accordingly.
This is a preliminary device tree mostly for U-Boot's own sake, it
is expected to be updated once the official DT gets accepted upstream.

The OrangePi PC 2 is a typical SBC with the 64-bit Allwinner H5 SoC.
Add a (64-bit only) defconfig defining the required options to build
the U-Boot proper and SPL.

> This series introduces support for the Allwinner H5 SoC with four
> Cortex-A53 cores. The SoC's peripherals are very similar to the H3,
> although the cores and the BROM/SRAM layout resembles the A64.
> The first 6 patches contain some fixes and refactoring, to make code
> sharing between the three mentioned SoCs easier.
> Patch 07/12 adds support for the H5 DRAM controller, by extending
> the already existing combined H3/A64 DRAM code.
> Patch 08/12 renames the existing CONFIG_MACH_SUN8I_H3 config symbol to
> let it be used by all peripheral code that can be shared between the
> H3 and H5. Patch 10/12 introduces the H5 SoC config option into Kconfig,
> which defines this shared symbol as well.
> Patch 11/12 adds an easy device tree, which actually uses the H3 .dtsi
> and overwrites nodes which are different. This is good enough for U-Boot,
> the DT will be changed anyway once we get the DT merged into the Linux
> kernel.
> The final patch then adds the defconfig for the OrangePi PC2 board.
> Since this board comes with soldered SPI flash, we enable support for
> it in the SPL. This has been tested by writing the SPI flash with some
> special sunxi-fel version. The BROM loaded and executed the SPL, which
> in turn loaded and executed U-Boot proper. Both parts are 64-bit only
> for now.
> Ethernet support is enabled, but fails at the moment since the EMAC
> driver does not support setting a GPIO to enable the external Gigabit PHY.
> This should be a problem for H3 boards with Gigabit as well.

No. It's me who should do rebase, as I have not done everything ;-)
