Diagnostic only, to be reverted before upstreaming: board_early_init_f
(orange), dram_init_banksize (blue), board_early_init_r (red) paint
bands into the depthcharge scanout to localize the early crash.
Add a display driver for the MT8183 kukui family of ChromeOS devices
(e.g. the Lenovo IdeaPad Duet, google,krane), where the display
pipeline is already initialized and running when the payload is
handed off by depthcharge. depthcharge's display_cleanup() stops the
overlay engines and turns the backlight off before the jump, so the
driver only revives the pipeline: it re-enables the OVL0 engines
(OVL_EN @ +0x000c and OVL0_2L_EN @ +0x100c, offsets from depthcharge's
device-era mtk_ddp.c), drives the backlight GPIOs high (DISP_PWM,
pin 43, and EN_LCD_BL, pin 176, through the GPIO controller dout block
at 0x10005000+0x100), and renders the console into the live scanout
surface.
The geometry comes from the coreboot table framebuffer record, which
sits at the fixed kukui address 0xffed9000; when its physical_address
is 0 (what upstream coreboot 4.14 publishes on kukui), the live
scanout address is taken from the OVL layer 0 address register
(+0x0f40), which the firmware leaves in place across the handoff.
The driver binds to the existing ovl0 device tree node
(mediatek,mt8183-disp-ovl) and requires no display initialization.
Device trees imported from Linux (dts/upstream) include their
dt-bindings headers from dts/upstream/include, but the dtc preprocessor
search order places U-Boot's legacy in-tree include/ first. When a SoC
has both a legacy dt-bindings header (used by non-upstream in-tree
device trees) and an upstream one, the legacy copy shadows the upstream
one and silently misresolves the clock/reset/power macros whose
numbering changed between generations.
Prefer dts/upstream/include when building with CONFIG_OF_UPSTREAM. The
upstream imported device trees are written against the upstream
bindings, and no current OF_UPSTREAM user builds legacy in-tree device
trees.
Add support for the Lenovo IdeaPad Duet (google,krane sku176), an
MT8183 ChromeOS tablet from the kukui family. The board boots through
coreboot + depthcharge, which load U-Boot as an arm64 Image at an
arbitrary 2 MiB-aligned DRAM slot; keep CONFIG_POSITION_INDEPENDENT
like the pumpkin target.
The board shares the pumpkin's board file, renamed to mt8183.c since it
is generic for the SoC. The defconfig uses the upstream devicetree from
dts/upstream (CONFIG_OF_UPSTREAM) and drops the pumpkin-specific USB
gadget/fastboot support for now.
SWIG 4.5.0 removed Python 2 compatibility macros (PyInt_*, PyString_*)
from its runtime header pyhead.swg (see commit 79f7a2b7cb7d). Replace
them with their Python 3 C API equivalents:
- PyString_FromString -> PyUnicode_FromString
- PyString_AsString -> PyBytes_AsString
- PyInt_AsLong -> PyLong_AsLong
The replacements are safe since the macros were already aliased to
these exact functions in SWIG's Python 3 code path.
This is a backport of dtc commit 5008d1d6a356 ("pylibfdt: Replace

dhcp_fine_tmr() was called every 10ms, but lwIP expects it to be
called every DHCP_FINE_TIMER_MSECS (500ms).
Since the fine timer ticks are currently 50 times faster than lwIP
expects, the client burns through the bounded exponential backoff
sequence for the DHCPREQUEST messages in 2.44 seconds rather than 122
seconds, after which it uses a new xid and returns to sending
DHCPDISCOVER messages. If there is enough latency in the server, the
client could receive an ACK response within DHCP_TIMEOUT_MS (10
seconds), but reject it because it has already moved on with another
xid after 2.44 seconds.
We have seen this occur with our boards. When our rack of 16 boards
get powered on together, they all request for an address from the
network switch's DHCP server in near lock-step and we see that only a
few of the boards actually obtain a lease. Fixing the timing to 500ms
allowed all of the boards to obtain a lease consistently.

Move the controller/PHY reset and SRAM-bypass sequence from
hce_enable_notify(PRE_CHANGE) into ufs_versal2_init().
The reset sequence releases the host controller from reset, and the UFS
core reads the capability and version registers right after .init() and
before ufshcd_hba_enable() (the only caller of hce_enable_notify()).
Doing the reset in .init() ensures those registers are read after the
controller is out of reset, and keeps the driver aligned with Linux.
ufs_versal2_phy_init() stays in POST_CHANGE.

Starting the GENFIFO after each CMD and ADDR entry creates a gap
between the address phase (TX) and data phase (RX). For read commands
without dummy cycles, the controller is still driving DQ2/DQ3 HIGH
when the flash switches to output mode, causing a bus conflict.
Split the GENFIFO helper into a write-only variant and a
start-and-wait variant. Queue CMD, ADDR and dummy entries without
starting the GENFIFO. The data phase appends its entry and starts
the queued sequence, keeping the address-to-data transition
continuous.
Since genfifo_cmd() no longer triggers after each entry, operations
without a data phase have no trigger path. Call start_gen_fifo()
from exec_op() before deasserting chip select to execute the queued
CMD and ADDR entries.

The GIC redistributor base address depends on the part: the 2VM3654
device has 4 APU cores and 3 GIC ITS blocks, which shifts the
redistributor region up compared to the base 8 core / single ITS part.
A single U-Boot binary must therefore pick the right base at runtime
instead of relying on the compile-time GICR_BASE used by the generic
lowlevel_init().
Add a SoC specific lowlevel_init() that reads the PMC TAP IDCODE and
selects GICR_BASE_2VM3654 for the 2VM3654 device, otherwise keeps the
default GICR_BASE. CONFIG_ARMV8_MULTIENTRY is not supported on Versal

Rockchip SoCs can automatically switch between jtag and sdmmc based on
the following rules:
- all the SDMMC pins including SDMMC_DET set as SDMMC function in GRF,
- force_jtag bit in GRF is 1,
- SDMMC_DET is low (no card detected),
Note that the BootROM may mux all SDMMC pins in their SDMMC function or
not, depending on the boot medium that were tried.
Because SDMMC_DET pin is not guaranteed to be used as an SD card card
detect pin, it could be low at boot or even switch at runtime, which
would enable the jtag function and render the SD card unusable.
Or boards using cd-gpios may switch the SDMMC_DET pin to GPIO function,
which would enable the jtag function and render the SD card unusable.
With commit d0a838bdc6 ("Subtree merge tag 'v7.1-dts' of dts repo [1]
into dts/upstream") there are now RK3576 boards that have changed to use
cd-gpios for the SDMMC_DET pin, e.g. NanoPi R76S, that may have issues
detecting SD card unless force_jtag is disabled.

- Fix a hotplug issue with pci_iommu_extra on Layerscape platforms for

caused by an unbounded TF-A DRAM bank loop and an integer underflow
when gd->arch.resv_ram is inadvertently left at zero due to empty DRAM

- Also includes a minor DT cosmetic cleanup.
The TF-A DRAM bank setup currently assumes that the number of
banks reported by TF-A matches the number of entries available in
gd->bd->bi_dram[]. Limit the loop by CONFIG_NR_DRAM_BANKS so that
a platform with fewer configured DRAM banks does not write past the
array.
The reserved RAM setup also checks higher DRAM banks before falling
back to bank 0. When a higher bank is empty and board_reserve_ram_top()
returns 0, the old test succeeds for a zero-sized bank. This can set
gd->arch.resv_ram to 0.
On systems with CONFIG_GIC_V3_ITS this value is later used by
ls_gic_rd_tables_init() to place the GIC LPI tables:
gd->arch.resv_ram - GIC_LPI_SIZE
If gd->arch.resv_ram is 0, the subtraction underflows and the GIC LPI
tables are placed at an invalid high address.
Skip empty banks when selecting the reserved RAM area and fail GIC LPI
table setup if no reserved RAM address was established.
This fixes LS1028A systems with 2 GiB of RAM, where TF-A reports only
one populated DRAM bank.
Tested on an LS1028ARDB with TF-A modified to report 2 GiB of RAM, and
on a custom LS1028A-based board equipped with 2 GiB of RAM.

In case MULTI_DTB_FIT_GZIP is enabled, fdtdec_setup() does uncompress
the compressed DTs in uncompress_blob() using gunzip(), which invokes
malloc() internally. The early simple malloc is initialized in board_f
initf_malloc() call, which sets up the early simple malloc limit and
offset pointer in global data. Currently, the initf_malloc() is called
after fdtdec_setup(), which leads to malloc failure in fdtdec_setup()
during the gzip decompression, because the early simple malloc is not
initialized yet.
Call initf_malloc() before fdtdec_setup() to assure fdtdec_setup() can
use malloc() during gzip decompression of the DTs.
The impact of this change on boot time is negligible, because the

When CONFIG_MULTI_DTB_FIT is enabled, fit-dtb.blob is produced by
mkimage with one "-b " argument for every entry in CONFIG_OF_LIST.
The make rule, however, only listed dts/dt.dtb (i.e. the
CONFIG_DEFAULT_DEVICE_TREE blob) as a prerequisite:
fit-dtb.blob: dts/dt.dtb FORCE
$(call if_changed,mkimage)
Because FORCE is PHONY, if_changed ignores it and rebuilds only when
any-prereq or arg-check is non-empty. Editing a non-default dts in
OF_LIST rebuilds its .dtb (tracked correctly via fixdep), but that
.dtb was not a prerequisite of fit-dtb.blob, so $? stayed empty; the
mkimage command line was unchanged too, so arg-check was empty as
well. if_changed therefore skipped mkimage and fit-dtb.blob kept the
stale dtbs. u-boot.bin, which appends fit-dtb.blob, then shipped the
old device tree and the dts change did not take effect.
A previous attempt to fix this added every OF_LIST .dtb *output* as a
prerequisite. That is wrong on two counts:
- Clean build regression: the OF_LIST .dtb files are produced only
by the recursive dts/dt.dtb -> arch-dtbs sub-make descent and have
no rule at the top make level, so listing them as prerequisites
makes them rule-less/intermediate. After a from-scratch rebuild
(e.g. wiping an out-of-tree build directory) it fails:
make[1]: *** No rule to make target 'arch/arm/dts/.dtb',
needed by 'fit-dtb.blob'. Stop.
- Incremental two-build race still present: the .dtb outputs are
written by a child sub-make descent while the parent make level
checks prerequisites, so under `make -j` an edit can still need
two make invocations to take effect.
List the .dts *sources* instead, which the top make level can see via
VPATH in both objtree and srctree. Use $(dt_dir), as
MKIMAGEFLAGS_fit-dtb.blob already does just below, so that
CONFIG_OF_UPSTREAM boards (whose sources live under dts/upstream/src/)
are handled too; a helper variable keeps the rule under 80 columns.
Limitation: this only catches edits to the top-level .dts files in
OF_LIST. An edit to an included .dtsi (including the *-u-boot.dtsi
files) rebuilds the .dtb but leaves fit-dtb.blob stale, so the
two-build problem remains in that case. Fixing that fully would need
the .dtb outputs (rather than the .dts sources) as prerequisites,
which reintroduces the clean-build problem above; covering top-level
.dts edits is already a worthwhile improvement.

Commit aa5ef3c0a7 ("bootretry: check for bootretry variable changes")
broke the feature where one can define different keys for "delaying"
versus "stopping" boot. The way the latter is implemented is by the code
in autoboot.c calling bootretry_dont_retry() when the stop sequence
has been detected, and that simply sets the retry_time variable in
bootretry.c to -1.
However, with the mentioned commit, that is unconditionally overridden
on every command, since it gets re-initialized from either the
bootretry environment variable or CONFIG_BOOT_RETRY_TIME, thus making
"delay" and "stop" effectively the same.
To fix that, while still picking up changes to the bootretry
environment variable, use the proper mechanism for C code to be
notified about changes to environment variables.
Since the callback is invoked before the change has actually been done
to the environment (callbacks can reject the change from taking
effect), we cannot simply call the existing
bootretry_init_cmd_timeout() from the callback, as its env_get() would
not see the new value. Instead, refactor most of it to an internal
bootretry_parse(), and call that with the new value (which is NULL in
the case bootretry is being deleted, so that works exactly as it
should).
