104950a7fe i2c: Add a DM_I2C driver for the sun6i P2WI controller
This bus controller is used to communicate with an X-Powers AXP PMIC.
Currently, various drivers access PMIC registers through a platform-
specific non-DM "pmic_bus" interface, which depends on the legacy I2C
framework. In order to convert those drivers to use DM_PMIC, this bus
needs a DM_I2C driver.

Refactor the p2wi functions to take the base address as a parameter,
and implement both the existing interface (which is still needed in
SPL) and the DM_I2C interface on top of them.

The register for switching between I2C/P2WI/RSB mode is the same across
all PMIC variants. Move that to the common header, so it can be used by
both interface implementations.

4ab39e74b6 sunxi: pmic_bus: Fix Kconfig dependencies
AXP_PMIC_BUS enables communication with a specific AXP PMIC at a
PMIC-dependent I2C/P2WI/RSB bus address. It is automatically selected
as a dependency of the PMIC driver. It should not be selectable by the
user when no PMIC is chosen.

AXP_GPIO uses the pmic_bus functions, and also depends on a specific
PMIC header to pick up register definitions.

Both of these changes have no impact on any existing configs, since
the code does not compile if the dependencies are not met.

abd2e783f1 sunxi: Select SUN8I_RSB more carefully
SUN8I_RSB should not be selected by MACH_SUN8I, because the hardware
is not present in half of those SoCs (H3/H5, R40, and V3s). Move the
selection to the SoCs where the hardware actually exists.
As it currently stands, selecting that option also requires using it in
some way, which is not the case for one A80 board. Since we have only
three A80 boards in total, we select it their via their defconfigs.

ea261fdeb2 sunxi: Only initialize legacy I2C when enabled
CONFIG_SPL_I2C is the wrong symbol to use here. It is the top-level
Kconfig symbol (not specific to either legacy or DM I2C), whereas the
i2c_init() function is specific to legacy I2C. This change fixes a

425084610e sunxi: Clean up inclusions of asm/arch/gpio.h
As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.

Some files did not contain any GPIO code at all, so this header was
completely unused.

A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.

The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.

dda9fa734f sunxi: Simplify MMC pinmux selection
Only one board, Yones Toptech BD1078, actually uses a non-default MMC
pinmux. All other uses of these symbols select the default value or an
invalid value. To simplify things, remove support for the unused pinmux
options, and convert the remaining option to a Boolean.

This allows the pinmux to be chosen by the preprocessor, instead of
having the code parse a string at runtime (for a build-time option!).
Not only does this reduce code size, but it also allows this Kconfig
option to be used in a table-driven DM pinctrl driver.

f9d1324775 sunxi: clock: H6/H616: Fix PLL clock factor encodings
Most clock factors and dividers in the H6 PLLs use a "+1 encoding",
which we were missing on two occasions.

This fixes the MMC clock setup on the H6, which could be slightly off due
to the wrong parent frequency:
mmc 2 set mod-clk req 52000000 parent 1176000000 n 2 m 12 rate 49000000

Also the CPU frequency (PLL1) was a tad too high before.

For PLL5 (DRAM) we already accounted for this +1, but in the DRAM code
itself, not in the bit field macro. Move this there to be aligned with
what the other SoCs and other PLLs do.

a5ff6f5c72 sunxi: enable dual rank memory on R40
Previously we do not have proper dual rank memory detection on R40
(because we omitted PIR_QSGATE, which does not work on R40 with our
configuration), and dual rank memory is just simply disabled as early
R40 boards available (Banana Pi M2 Ultra and Berry) have single rank
memory.

As a board with dual rank memory (Forlinx OKA40i-C) is now known to us,
we need to have a way to do memory rank detection to support that board.

Add some routine to detect memory rank by trying to access the memory
in rank 1 and check for error status of the memory controller, and then
enable dual rank memory on R40.

Similar routine can be used to detect half DQ width (which is also
detected by PIR_QSGATE on other SoCs), but it's left unimplemented
because there's no known R40 board with half DQ width now.

e9dfd8e960 sunxi: support asymmetric dual rank DRAM on A64/R40
Previously we have known that R40 has a configuration register for its
rank 1, which allows different configuration than rank 0. Reverse
engineering of newest libdram of A64 from Allwinner shows that A64 has
this register too. It's bit 0 (which enables dual rank in rank 0
configuration register) means a dedicated rank size setup is used for
rank 1.

Now, Pine64 scheduled to use a 3GiB LPDDR3 DRAM chip (which has 2GiB
rank 0 and 1GiB rank 1) on PinePhone, that makes asymmetric dual rank
DRAM support necessary.

Add this support. The code could support both A64 and R40, but because
dual rank detection is broken on R40 now, we cannot really use it on R40
currently.

5d235324ae video: sunxi_display: Convert to DM_VIDEO
DM_VIDEO migration deadline is already expired, but around
80 Allwinner boards are still using video in a legacy way:

===================== WARNING ======================
This board does not use CONFIG_DM_VIDEO Please update
the board to use CONFIG_DM_VIDEO before the v2019.07 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/migration.rst for more info.
====================================================

Convert the legacy video driver over to the DM_VIDEO framework. This is
a minimal conversion: it doesn't use the DT for finding its resources,
nor does it use DM clocks or DM devices for the outputs (LCD, HDMI, CVBS).

Tested in Bananapi M1+ Plus 1920x1200 HDMI out. (Jagan)

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;

Allwinner V3/Sochip S3 uses the same die with Allwinner V3s/S3L, but V3 comes
with no co-packaged DDR (DDR3 is usually used externally), and S3L comes
with co-packaged DDR3.

Add support for Allwinner V3/S3 chips by add SoC names to original V3s
choice, and allow to select DDR3.

Previously, because we have no source code about the DRAM initialization
of V3s and missing some configurations (delays and MBUS QoS info), our
V3s DRAM initialization sequence is hacked from the H3 one.

As the SDK shipped with PineCube contains source code for V3s libdram,

fd40ad0d57 sunxi: SPL SPI: Add SPI boot support for the Allwinner H6 SoC
The Allwinner H6 SoC uses a quite different memory map, also changes the
clocks quite a bit. This requires some changes to the SPL SPI routine,
which hardcodes these values so far.

Using the just introduced helper functions to determine base address
and SPI controller generation, we can cover some of these differences
easily.
The clock setup is different, so requires some explicit code changes
there (reset and clock gate in one register at a different address).
Also we need to change the pinmux function to use a different set of
pins that the H6 uses for SPI0.

Eventually we can enable the H6 to use SPI booting in Kconfig.

56f51f3875 sunxi: SPL SPI: Introduce is_sun6i_gen_spi()
So far we were using the CONFIG_SUNXI_GEN_SUN6I symbol to select between
the two SPI controller generations used on Allwinner SoCs. This is a
convenience symbol to roughly differentiate between "older" and "newer"
generation of SoCs.

The H6 SoCs is the newest SoC so far, but is sufficiently different to
not define this symbol. However it is using a SPI controller compatible
to the "new gen" SoCs.

To prepare for H6 support, we replace the check for this single symbol
with an explicit function, which can later be extended.
For now we just return CONFIG_SUNXI_GEN_SUN6I in there, so this does not
create a functional change.

2775e08a2b sunxi: SPL SPI: Split off SPI0 base address
So far on all supported Allwinner SoCs we find the old generation SPI
controller always at address 0x1c05000, and the new generation one at
0x1c68000. However the Allwinner R40 SoC has a new generation SPI at
the old address, and the H6 uses a completely different address.

So split off the base address from the respective SPI registers, by
changing the #defines to just contain offsets.
The base address is provided by a function, so it can easily be extended
later when support for those SoCs materialises.

This does not change the code size (since the toolchain is clever enough
to optimise this properly), also does not bring any functional change at
this point.

7c841d844f sunxi: Automate loading from 128KB MMC offset
Since commit 067e0b9684 ("sunxi: Allow booting from 128KB SD/eMMC offset")
we support having the SPL loaded from either the traditional 8KB SD
card/eMMC offset, or from the alternative location at 128KB. However the
sector to find the U-Boot image was still hard-coded at compile time,
and had to be adjusted for one of the two choices.

Since we can actually override the function to return the sector offset,
we can just check the boot source byte there to select the proper offset
based on from where the SPL was loaded.

This allows the very same binary image to be loaded from either 128KB or
8KB, with the U-Boot proper image always being located just behind the SPL.

With the current calculation, m = 2 and k = 3. Solving for n,
this results 28. Solving back:
  (24MHz * 28 * 3) / 2 = 1008MHz

However if the requested clock is 816, n is 22.66 rounded
to 22, which results:
  (24MHz * 28 * 3) / 2 = 792MHz

Changing k to 4 satisfies both system clocks:
  (24E6 * 21 * 4) / 2 = 1008MHz
  (24E6 * 17 * 4) / 2 = 816MHz

067e0b9684 sunxi: Allow booting from 128KB SD/eMMC offset
On modern Allwinner SoCs (tested: H2+, A64, H5, H6) the BootROM can
actually load the SPL also from sector 256 (128KB) of an SD card or eMMC
chip. For more details, see [1].
In this case the boot source indicator (written at offset 0x28 of SRAM A1)
has bit 4 set, so it's 0x10 for SD card and 0x12 for eMMC.

Add those new values to the existing boot source check to allow booting
the SPL from those "high" disk offsets as well. For this to work, the
value of CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR needs to be adjusted,
for instance to 0x140 (right after the high SPL). Doing this dynamically
sounds desirable, but looks nasty to implement.

ddd6930215 sunxi: dram_sun8i: Fix A33 memory initialization
While the exact problem is not known, based on discussion between
Philipp Tomsich and André Przywara it is guessed that exit self-refresh
timing is not set with correct value. There may be implicit enter or
exit Self-Refresh anywhere as part of some training phase.

In ZynqMP register guide [1], which is close to the various
Allwinner DRAM controllers, tXSDLL is bits [14:8], while the non-DLL
tXS is bits [6:0]: Self refresh exit delay. So it could be safely
increased and it only affects the time after the self-refresh “exit”,
which happens only after (re-)initialisation.

There was no document for cpu in question so based on oscilloscope
readings [2][3] and observed result by comparing allwinner architecture.
So set it same as  Allwinner H5 silicon.

Before this patch, failure rate of was 7%.

This was tested on A33 allwinner cpu, dual rank connection connected
with two MT41K512M16HA-125:A memory model. Memory is configured as DDR3

85c3d46322 arm: sunxi: Enable DM_MMC on required SoCs
Enabling DM_MMC is forcing CONFIG_BLK=y so if any board which uses
SCSI must need to enable DM_SCSI otherwise SCSI reads on that particular
target making invalid reading to the disk drive.

Allwinner platform do support SCSI on A10, A20 and R40 SoC's out of
these only A10 have DM_SCSI enabled. So enabling DM_MMC on A20, R40
would eventually end-up with scsi disk read failures like [1]

So, enable DM_MMC in all places of respective SoC's instead of enabling
them globally to Allwinner platform.

Now, DM_MMC is enabled in Allwinner SoC's except A20 and R40.

f8aa3f8d84 sunxi: add Kconfig option for the maximum accessible DRAM
Allwinner 64-bit SoCs can use 4GiB DRAM chip, however their memory map
has only allocated 3GiB for DRAM, so only 3GiB of the DRAM is
accessible.

Add a Kconfig option for the maximum accessible DRAM.

For A80 it should be a much higher value (8GiB), but as I have no A80
device to test and originally U-Boot only supports 2GiB DRAM on A80, it
currently still falls under the 2GiB situation.

c6c2c85e4b sunxi: disable Pine A64 model detection code on other boards
The Pine A64 Plus/non-Plus model detection code is now built on all
64-bit ARM SoCs, even if the code cannot be triggered when H5/H6 is in

Disable them when the board is Pine A64 by adding a Kconfig option that
is only selected on Pine A64.

On GCC 7.3.1 this makes the size of the function reduces 184 bytes, and
saves a 104 byte strstr() function, then makes SPL on H6 succeed to
build.

"default" lines in Kconfig are processed in order, the first hit will
stop considering subsequent lines. In the case of the DRAM_ODT_EN symbol
that means that everything following the first two lines will never be
checked:
------------
config DRAM_ODT_EN
	bool "sunxi dram odt enable"
	default n if !MACH_SUN8I_A23
	default y if MACH_SUN8I_A23
	default y if MACH_SUN8I_R40
	default y if MACH_SUN50I
------------

Assuming that the "default y" for the A64 and the R40 were a deliberate
choice, fix the Kconfig stanza to take this into account.
Also remove the now redundant lines from the respective defconfigs.

da2616543a sunxi: add DRAM support to H6
The Allwinner H6 SoC comes with a set of new DRAM controller+PHY combo.
Both the controller and the PHY seem to be originate from DesignWare,
and are similar to the ones in ZynqMP SoCs.

This commit introduces an initial DRAM driver for H6, which contains
only LPDDR3 support. The currently known SBCs with H6 all come with
LPDDR3 memory, including Pine H64 and several Orange Pi's.

The BSP DRAM initialization code is closed source and violates GPL. Code
in this commit is written by experimenting, referring the code/document
of other users of the IPs (mainly the ZynqMP, as it's the only found PHY
reference) and disassebling the BSP blob.

Thanks for Jernej Skrabec for review and fix some issues in this driver
(including the most critical one which made it to work), and rewrite
some code from register dump!

be0d217952 arm: timer: sunxi: add Allwinner timer erratum workaround
The Allwinner A64 SoCs suffers from an arch timer implementation erratum,
where sometimes the lower 11 bits of the counter value erroneously
become all 0's or all 1's [1]. This leads to sudden jumps, both forwards and
backwards, with the latter one often showing weird behaviour.
Port the workaround proposed for Linux to U-Boot and activate it for all
A64 boards.
This fixes crashes when accessing MMC devices (SD cards), caused by a
recent change to actually use the counter value for timeout checks.

Fixes: 5ff8e54888 ("sunxi: improve throughput
in the sunxi_mmc driver")
