This makes the U-Boot SPI NAND driver almost the same as in Linux 6.10.
The only major difference is support of ECC engines. The Linux driver
supports different ECC engines while U-Boot uses on-die ECC only.

This reverts commit 9fe2e4b464.
Commit 9fe2e4b464 ("fdt: Make sure there is no stale initrd left")
introduces a regression in case when U-Boot transfers control to an EFI
app which acts as a subsequent bootloading program. Such an app might
try to set "linux,initrd-start" and "linux,initrd-end" fdt properties,
but by that time those properties are already removed by the code added
in the mentioned commit.
Particularly, the issue was observed on the E850-96 board where GBL EFI
app [1] can't run Android successfully anymore. More specifically, the
kernel can't see the ramdisk and panics with next messages:
/dev/root: Can't open blockdev
VFS: Cannot open root device "" or unknown-block(0,0): error -6
Please append a correct "root=" boot option; ...
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
fdt_initrd() function (where initrd dts properties are removed) is
called two times:
1. First it's called by EFI boot manager (e.g. as a part of U-Boot
Standard Boot mechanism) when it's installing FDT:
fdt_initrd
image_setup_libfdt
efi_install_fdt
efi_bootmgr_run
efi_mgr_boot
It's already enough for EFI app to malfunction. But then it's also
called second time:
2. From the EFI app, via EFI DT fixup protocol:
fdt_initrd
image_setup_libfdt
efi_dt_fixup
struct efi_dt_fixup_protocol efi_dt_fixup_prot = {
.fixup = efi_dt_fixup
};
See [2] for specific GBL code which sets those fdt properties and then
runs DT fixup protocol callback.
This issue was discussed [3], but no action was taken since then. Revert
this patch for now, until a proper solution can be found.

cover letters and recipient lists, run style checks, and send patches

Once the DHCP exchange is complete, if we have an IP address for an NTP
server, set the ntpserverip environment variable accordingly. Although
not necessary to make the sntp command use that server (since it is
known internally to the lwIP stack), this makes the behavior in line
with the legacy NET stack. This is also consistent with exporting the

While it is good that the "Licenses/" directory contains the text
for all licenses that are applicable to u-boot code, it is harder
to determine at a glance what the default and/or preferred license
is. While humans can look at the Licenses/README file, this is not
machine parseable, making it tricky for license detection tools to
automatically determine/report on the overall / aggregate u-boot
license.
The project previously had a top level COPYING file containing a
short blurb, followed by the GPL license text. This was removed
back in commit eca3aeb352 when
the "Licenses/" directory was introduced. For the benefit of
automated tools, it is helpful to retain a top level COPYING
file in the repository. Rather than duplicate the license text,
however, a symlink from the Licenses/gpl-2.0.txt file should
suffice.

Figure 9.3.2 Software Reset flow (B) indicates that for peripherals in HSC
domain, after reset has been asserted by writing a matching reset bit into
register SRCR, it is mandatory to wait 1ms.
Because it is the controller driver which can determine whether or not the
controller is in HSC domain based on its compatible string, add the missing
delay into the controller driver.
This 1ms delay is documented on R-Car V4H and V4M, it is currently unclear
whether S4 is affected as well. This patch does apply the extra delay on
R-Car S4 as well.

Assure the reset is latched and the core is ready for DBI access.
On R-Car V4H, the PCIe reset is asynchronized and does not take
effect immediately, but needs a short time to complete. In case
DBI access happens in that short time, that access generates an
SError. Make sure that condition can never happen, read back the
state of the reset which should turn the asynchronized reset into
synchronized one, and wait a little over 1ms to add additional
safety margin.
