3b46cdd7a0 arm: Disable SPL_FS_FAT when it isn't used
Several boards enable SPL_FS_FAT and SPL_LIBDISK_SUPPORT when they can't be
used (as there is no block device support enabled). Disable these configs.
The list of boards was generated with the following command:

    $ tools/qconfig.py -f SPL SPL_FS_FAT ~SPL_MMC ~SPL_BLK_FS ~SPL_SATA \
                          ~SPL_USB_STORAGE ~ENV_IS_IN_FAT ~EFI

LIBDISK was left enabled for the am* boards, since it seems to result in
actual size reduction, indicating that partitions are being used for
something.

a9a7379973 arm: Enable SYS_THUMB_BUILD on AT91
Several AT91 boards are quite close to their SPL size limit. For example,
sama5d27_wlsom1_ek_mmc is just 173 bytes short of its limit and doesn't
even fit with older GCCs.

All AT91 processors should have thumb support. Enable SYS_THUMB_BUILD. This
shrinks SPL by around 30%.

8502b5bf20 test: spl: Add a test for NAND
Add a SPL test for the NAND load method. We use some different functions to
do the writing from the main test since things like nand_write_skip_bad
aren't available in SPL.

We disable BBT scanning, since scan_bbt is only populated when not in SPL.
We use nand_spl_loaders.c as it seems to be common to at least a few boards
already. However, we do not use nand_spl_simple.c because it would require
us to implement cmd_ctrl.  The various nand load functions are adapted from
omap_gpmc. However, they have been modified for simplicity/correctness.

bc8e8a4bfa nand: Add sandbox driver
Add a sandbox NAND flash driver to facilitate testing. This driver supports
any number of devices, each using a single chip-select. The OOB data is
stored in-band, with the separation enforced through the API.

For now, create two devices to test with. The first is a very small device
with basic ECC. The second is an 8G device (chosen to be larger than 32
bits). It uses ONFI, with the values copied from the datasheet. It also
doesn't need too strong ECC, which speeds things up.

Although the nand subsystem determines the parameters of a chip based on
the ID, the driver itself requires devicetree properties for each
parameter. We do not derive parameters from the ID because parsing the ID
is non-trivial. We do not just use the parameters that the nand subsystem
has calculated since that is something we should be testing. An exception
is made for the ECC layout, since that is difficult to encode in the device
tree and is not a property of the device itself.

Despite using file I/O to access the backing data, we do not support using
external files. In my experience, these are unnecessary for testing since
tests can generally be written to write their expected data beforehand.
Additionally, we would need to store the "programmed" information somewhere
(complicating the format and the programming process) or try to detect
whether block are erased at runtime (degrading probe speeds).

Information about whether each page has been programmed is stored in an
in-memory buffer. To simplify the implementation, we only support a single
program per erase. While this is accurate for many larger flashes, some
smaller flashes (512 byte) support multiple programs and/or subpage
programs. Support for this could be added later as I believe some
filesystems expect this.

To test ECC, we support error-injection. Surprisingly, only ECC bytes in
the OOB area are protected, even though all bytes are equally susceptible
to error. Because of this, we take care to only corrupt ECC bytes.
Similarly, because ECC covers "steps" and not the whole page, we must take
care to corrupt data in the same way.

38ef64e6ce spl: nand: Set bl_len to page size
Since commit 34793598c8 ("mtd: nand: mxs_nand_spl: Remove the page aligned
access") there are no longer any users of nand_get_mtd. However, it is
still important to know what the page size is so we can allocate a
large-enough buffer. If the image size is not page-aligned, we will go off
the end of the buffer and clobber some memory.

Introduce a new function nand_page_size which returns the page size. For
most drivers it is easy to determine the page size. However, a few need to
be modified since they only keep the page size around temporarily.

It's possible that this patch could cause a regression on some platforms if
the offset is non-aligned and there is invalid address space immediately
before the load address. spl_load_legacy_img does not (except when
compressing) respect bl_len, so only boards with SPL_LOAD_FIT (8 boards) or
SPL_LOAD_IMX_CONTAINER (none in tree) would be affected.

a75cf70d23 efi: Correct handling of frame buffer
The efi_gop driver uses private fields from the video uclass to obtain a
pointer to the frame buffer. Use the platform data instead.

Check the VIDEO_COPY setting to determine which frame buffer to use. Once
the next stage is running (and making use of U-Boot's EFI boot services)
U-Boot does not handle copying from priv->fb to the hardware framebuffer,
so we must allow EFI to write directly to the hardware framebuffer.

We could provide a function to read this, but it seems better to just
document how it works. The original change ignored an explicit comment
in the video.h file ("Things that are private to the uclass: don't use
these in the driver") which is why this was missed when the VIDEO_COPY
feature was added.

70d2c9940e mmc: renesas-sdhi: Disable clock after tuning reset when possible
Currently the renesas_sdhi_reset_tuning() unconditionally leaves SDHI
clock enabled after the tuning reset. This is not always necessary.

After the driver performed tuning reset at the end of probe function,
or in the unlikely case that tuning failed during regular operation,
the SDHI clock can be disabled after the tuning reset. The following
set_ios call would reconfigure the clock as needed.

In case of regular set_ios call which requires a tuning reset, keep
the clock enabled or disabled according to the mmc->clk_disable state.

With this in place, the controllers which have not been accessed via
block subsystem after boot are left in quiescent state. However, if an
MMC device is used e.g. for environment storage, that controller would
be accessed during the environment load and left active, including its
clock which would still be generated. This is due to the design of the
MMC subsystem, which does not deinit a controller after it was started
once, the controller is only deinited in case of mmc rescan, or before
OS boot.

92b27528d7 Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
To quote Andre:

The first few patches are some easy refactorings and fixes, most of them
actually don't change the generated binaries at all. Then there is a
defconfig for a new board, for which we just gained the .dts file from
the last kernel DT sync.
On top there is support for a new PMIC (AXP313), and LPDDR4 support for
the Allwinner H616 SoC, both of which are needed to support new devices
that appeared lately, especially cheap TV boxes.

While those are technically new features, they don't affect existing
boards, for instance the LPDDR4 support code is guarded by a new DRAM
type Kconfig variable. So the risk for regressions is very slim.

Gitlab CI passed, and I booted that briefly on some boards, including an
H616 and an H618 one (with LPDDR4).

4b02f0120a sunxi: H616: add LPDDR4 DRAM support
The H616 SoC family has support for several types of DRAM: DDR3,
LPDDR3, DDR4 and LPDDR4.
At the moment, the driver only supports DDR3 and LPDDR3 memory.
Let's extend the driver to support the LPDDR4 memory. This type
of memory widely used in device with T507(-H) SoC and new orangepi
zero3 with H618.
The compatibility with T507 is not yet complete, because there
is difference in the phy_init array.
The LPDDR4-2133 timings correspond to DRAM Rayson RS1G32LO4D2BDS-53BT
found on the NOR SPI from the Orangepi Zero 3 4GB.

b71129ca3b sunxi: H616: DRAM: refactor mctl_phy_configure_odt()
The original H616 DDR3 ODT configuration code wrote board specific values
into a sequence of paired registers.
For LPDDR3 support we needed to special-case one group of registers,
because for that DRAM type we need to write 0 into the lower register of
each pair. That already made the code less readable.

LPDDR4 support will make things even messier, so let's refactor that
code now: We allow to write different values into the lower and upper
half of each pair. The masking is moved into a macro, and use in each
write statement.

The effect is not as obvious yet, as we don't need the full flexibility at
the moment, but the motivation will become clearer with LPDDR4 support.

fafedff350 power: regulator: add AXP313 support
The X-Powers AXP313a is a small PMIC with just three buck converters and
three LDOs, one of which is actually fixed (so not modelled here).

Add the compatible string and the respective regulator ranges to allow
drivers to adjust voltages.

d17d051c54 power: pmic: sunxi: add AXP313 SPL driver
On boards using the AXP313 PMIC, the DRAM rail is often not setup
correctly at reset time, so we have to program the PMIC very early in
the SPL, before running the DRAM initialisation.

Add a simple AXP313 PMIC driver that knows about DCDC2(CPU) and
DCDC3(DRAM), so that we can bump up the voltage before the DRAM init.
