board: samsung: Fix SYS_CONFIG_NAME configs in axy17lte Kconfig
There is a couple of issues related to SYS_CONFIG_NAME config in
axy17lte Kconfig.
1. The global SYS_CONFIG_NAME in axy17lte Kconfig overrides
SYS_CONFIG_NAME for all boards specified after this line in
arch/arm/mach-exynos/Kconfig:
source "board/samsung/axy17lte/Kconfig"
Right now it's the last 'source' line there, so the issue is not
reproducible. But once some board is moved or added after this line
the next build error will happen:
GEN include/autoconf.mk.dep
In file included from ./include/common.h:16:
include/config.h:3:10: fatal error: configs/exynos78x0-common.h.h:
No such file or directory
3 | #include <configs/exynos78x0-common.h.h>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
That's happening because axy17lte Kconfig defines SYS_CONFIG_NAME
option in global namespace (not guarded with any "if TARGET_..."), so
it basically rewrites the correct SYS_CONFIG_NAME defined in the
hypothetical boards which might appear after axy17lte in mach-exynos
Kconfig.
2. Another side of the issue is that SYS_CONFIG_NAME is defined
incorrectly in axy17lte Kconfig:
The .h extension should not have been specified there. It's leading
to a build error, as the generated include file has a double '.h'
extension.
3. Each target in axy17lte/Kconfig defines its own SYS_CONFIG_NAME. But
all of those in fact incorrect, as corresponding
include/configs/<CONFIG_SYS_CONFIG_NAME>.h header files don't exist.
4. The global SYS_CONFIG_NAME pretty much repeats the help description
from arch/Kconfig and doc/README.kconfig.
Corresponding defconfig files (a*y17lte_defconfig) fix above issues by
overriding SYS_CONFIG_NAME and correctly setting it to
"exynos78x0-common".
Fix all mentioned issues by removing the incorrect global
SYS_CONFIG_NAME and instead specifying it (correctly) in SYS_CONFIG_NAME
options for each target instead.

So enabling it again left it in a broken state. The problem occurred for

During the first setup, when the out request is queued, the endpoint is
primed (`epprime`). If the endpoint is then disabled, it stayed primed
with the initial buffer. So after the endpoint is re-enabled, the device
controller and device driver were out of sync: the new out request was
in the driver queue head, yet not submitted, but the "complete" function
was still called, since the endpoint was primed with the old buffer.
With the fastboot function this error led to the (rather confusing)

efi_loader: Increase default variable store size to 128K

Alper has a detailed explanation of why the size needs to be bumped to at
least 64K. However enabling Secure boot, writing db, KEK, PK etc keys
will further increase the size so bump it to 128K.
It's worth noting that when U-Boot stores the EFI variables in an RPMB the
available storage is defined statically in StandAloneMM at build time.
The U-Boot code is detecting the available true size on the fly during
writes. When StandAloneMM is present this size defines the reserved
memory U-Boot can use to copy any runtime variables, before booting an
OS.

virtio: rng: gracefully handle 0 byte returns
According to the virtio v1.x "entropy device" specification, a virtio-rng

However the virtio v0.9 spec does not mention such a requirement.
The Arm Fixed Virtual Platform (FVP) implementation of virtio-rng always
returns 8 bytes less of entropy than requested. If 8 bytes or less are
requested, it will return 0 bytes.
This behaviour makes U-Boot's virtio_rng_read() implementation go into an

Work around this problem by always requesting 8 bytes more than needed,

After the driver performed tuning reset at the end of probe function,

In case of regular set_ios call which requires a tuning reset, keep

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).
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.

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

sunxi: board: simplify early PMIC setup conditions
So far we have a convoluted #ifdef mesh that guards the early AXP PMIC
setup in board.c. That combination of &&, || and negations is very hard
to read, maintain and especially to extend.
Fortunately we have those same conditions already modelled in the
Kconfig file, so they are actually redundant. On top of that the real
reason we have those preprocessor guards in the first place is about the
symbols that are *conditionally* defined: without #ifdefs the build
would break because of them being undefined for many boards.
To simplify this, just change the guards to actually look at the symbols
needed, so CONFIG_AXP_xxx_VOLT instead of CONFIG_AXPyyy_POWER.
This drastically improves the readability of this code, and makes adding
PMIC support a pure Kconfig matter.
Doing this revealed one bug in Kconfig: there is no axp_set_dcdc4() for
the AXP818, even though CONFIG_AXP_DCDC4_VOLT includes that PMIC.
Since the AXP818 wasn't included when calling axp_set_dcdc4() in board.c,
this wasn't an issue, but becomes one now, so also remove the AXP818 from
the DCDC4 Kconfig symbol.

To quote the author:
Since commit [1], Ethernet is broken on TI AM62 and AM64 platforms.
The commit [1] is not the culprit. It just unearths the problem by fixing
the error check in k3-udma.c. This issue was silently being ignored earlier
due to wrong error check. [NULL instead of FDT_ADDR_T_NONE].
Fix the issue by adding the necessary register spaces for the u-boot K3-UDMA
driver for AM62 and AM64 platforms.
These properties will eventually make it into the SoC DTSi files [2] after
which these can be dropped from k3-*-u-boot.dtsi files.

absence of DM services. u-boot k3-udma driver expects these additional

bootstd: Skip over bad device during bootflows scanning
During bootstd scanning for bootdevs, if bootdev_hunt_drv() encounters
a device not found error (e.g. ENOENT), let it return a successful status
so that bootstd will continue scanning the next devices, not stopping
prematurely.
Background:
During scanning for bootflows, it's possible for bootstd to encounter a
faulty device controller. Also when the same u-boot is used for another
variant of the same board, some device controller such as SATA might
not exist.
I've found this issue while converting the Marvell Sheevaplug board to
use bootstd. This board has 2 variants, the original Sheevaplug has MMC and
USB only, but the later variant comes with USB, MMC, and eSATA ports. We
have been using the same u-boot (starting with CONFIG_IDE and later with DM
CONFIG_SATA) for both variants. This worked well with the old
envs-scripting booting scheme.

Keep track of the re-entries with help of the lr register.
This binary can be re-used and called from various BROM functions.
Only when it's called from the part that handles SPI, NAND or EMMC
hardware it needs to early return to BROM ones.
In download mode when it handles data on USB OTG and UART0
this section must be skipped.
Unlike newer Rockchip SoC models the rk3066 BROM code does not have built-in
support to enter download mode on return to BROM. This binary must check
the boot mode register for the BOOT_BROM_DOWNLOAD flag and reset if it's set.
It then returns to BROM to the end of the function that reads boot blocks.
From there the BROM code goes into a download mode and waits for data
on USB OTG and UART0.

rockchip: ringneck-px30: always reset STM32 companion controller on boot
It's happened that glitches on the STM32_RST and STM32_BOOT lines have
put the STM32 companion microcontroller into DFU mode making it not boot

Considering that the STM32 companion microcontroller is always reset on
a reboot or power cycle, resetting it once again in U-Boot SPL isn't
going to hurt it any more.
For ATtiny companion microcontroller, the situation is a bit different
because a reboot or power cycle doesn't reset it. Additionally, since it
can only be reset with a UPDI reset on the STM32_RST line, and that is
virtually impossible to mistakenly trigger, the ATtiny is unlikely to be
in unwanted reset or enter reset because U-Boot toggles STM32_RST line.
