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.

Now that we can easily select an SoC specific SPI0 base address, adding
support for the Allwinner R40 is fairly trivial:
We set the base address, add this SoC to the ones that use PC23 and
enable it in Kconfig.
This allows booting from SPI flash on R40 boards.
Tested on a Bananapi M2 Berry with SPI flash connected to the header pins.

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.

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.

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.

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.

While the exact problem is not known, based on discussion between

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.

The new Allwinner H6 SoC has its SRAM A1 at neither 0x0 nor 0x10000, but
it's at 0x20000. Thus the SUNXI_HIGH_SRAM option needs to be refactored
to support this new configuration.
Change it to SUNXI_SRAM_ADDRESS, which holds the real address of SRAM
A1 in the memory map.

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.

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.
As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This converts the following to Kconfig:

We have existing entries for this option in a number of places, with
different guards on them. They're also sometimes used for things not
directly inside of the serial driver. First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it. Next, consolidate all of these into the single entry in
drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.

As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved

matches, so please keep these values at the end of each file (to allow

This converts the following to Kconfig:

CONFIG_ENV_IS_IN_UBI
CONFIG_ENV_IS_NOWHERE
In fact this already exists for sunxi as a 'choice' config. However not
all the choices are available in Kconfig yet so we cannot use that. It
would lead to more than one option being set.
In addition, one purpose of this series is to allow the environment to be
stored in more than one place. So the existing choice is converted to a
normal config allowing each option to be set independently.
There are not many opportunities for Kconfig updates to reduce the size of
this patch. This was tested with
./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC
And then manual updates. This is because for CHAIN_OF_TRUST boards they
can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic

The DesignWare-like DRAM code used to set the controller defaultly to
single rank mode, which makes it not able to detect the second rank.
Set the default value to dual rank, thus the rank detection code can
work and finally the rank setting will be the correct value.
Currently we know little about the dual-rank on R40, and the usage
of A15 address line seems to be breaking dual-rank support. The only R40
board currently available (Sinovoip Banana Pi M2 Ultra) uses A15 rather
than dual-rank, thus we cannot do research for it. So dual rank detection
is temporarily disabled on R40.
This change is tested on a Orange Pi One (H3, single rank), a Pine64+
