This fixes the case where there are multiple environment drivers, one of
them is the default environment one, and it is followed by an environment
driver which does not implement .init() callback. The default environment
driver sets gd->env_valid to ENV_INVALID and returns 0 from its .init()
callback implementation, which is valid behavior for default environment.
Since the subsequent environment driver does not implement .init(), it
also does not modify the $ret variable in the loop. Therefore, the loop
is exited with gd->env_valid=ENV_INVALID and ret=0, which means that the
code further down in env_init() will not reset the environment to the
default one, which is incorrect.
This patch sets the $ret variable back to -ENOENT in case the env_valid
is set to ENV_INVALID by an environment driver, so that the environment
would be correctly reset back to default one, unless a subsequent driver
loads a valid environment.

Since commit 0f036bf4b8 ("env: Warn on force access if ENV_ACCESS_IGNORE_FORCE set")
a warning message is displayed when setenv -f is used WITHOUT
CONFIG_ENV_ACCESS_IGNORE_FORCE, but the variable is set anyway, resulting
in lots of log pollution.
env_flags_validate() returns 0 if the access is accepted, or non zero
if it is refused.
So the original code
#ifndef CONFIG_ENV_ACCESS_IGNORE_FORCE
if (flag & H_FORCE)
return 0;
#endif
was correct, it returns 0 (accepts the modification) if forced UNLESS
IGNORE_FORCE is set (in which case access checks in the following code
are applied). The broken patch just added a printf to the force accepted
case.
To obtain the intent of the patch we need this:
if (flag & H_FORCE) {
#ifdef CONFIG_ENV_ACCESS_IGNORE_FORCE
printf("## Error: Can't force access to \"%s\"\n", name);
#else
return 0;
#endif
}

If one of the reads fails when importing redundant environments (a
single read failure), the env_flags wouldn't get initialized in
env_import_redund(). If a user then calls saveenv, the new environment
will have the wrong flags value. So on the next load the new environment
will be ignored.
While debugging this, I also noticed that env/sf.c was not correctly
handling a single read failure, as it would not check the crc before
assigning it to gd->env_addr.
Having a special error path for when there is a single read failure
seems unnecessary and may lead to future bugs. Instead collapse the
'single read failure' error to be the same as a 'single crc failure'.
That way env_check_redund() either passes or fails, and if it passes we
are guaranteed to have checked the CRC.

This is roughly the U-Boot side equivalent to commit
e282c422e0 (tools: fw_env: use erasesize from MEMGETINFO ioctl). The
motivation is the case where one has a board with several revisions,
where the SPI flashes have different erase sizes.
In our case, we have an 8K environment, and the flashes have erase
sizes of 4K (newer boards) and 64K (older boards). Currently, we must
set CONFIG_ENV_SECT_SIZE to 64K to make the code work on the older
boards, but for the newer ones, that ends up wasting quite a bit of
time reading/erasing/restoring the last 56K.
At first, I wanted to allow setting CONFIG_ENV_SECT_SIZE to 0 to mean
"use the erase size the chip reports", but that config
option is used in a number of preprocessor conditionals, and shared
between ENV_IS_IN_FLASH and ENV_IS_IN_SPI_FLASH.
So instead, introduce a new boolean config option, which for now can
only be used with ENV_IS_IN_SPI_FLASH. If left off, there's no change
in behaviour.
The only slightly annoying detail is that, when selected, the compiler
is apparently not smart enough to see that the the saved_size and
saved_offset variables are only used under the same "if (sect_size >
CONFIG_ENV_SIZE)" condition as where they are computed, so we need to
initialize them to 0 to avoid "may be used uninitialized" warnings.
On our newer boards with the 4K erase size, saving the environment now
takes 0.080 seconds instead of 0.53 seconds, which directly translates
to that much faster boot time since our logic always causes the
environment to be written during boot.

CONFIG_SYS_REDUNDAND_ENVIRONMENT is changing in env_internal.h how u-boot

which also affects ENV_SIZE macro.
I have reached the case where CONFIG_ENV_IS_NOWHERE is default setup
but custom scripts can be designed in a way that u-boot is asked to
import/export variables from/to file which can be in certain format.
That's why also for this configuration make sense to enable

format.
The patch is removing dependency on this configuration to support selecting

Change:
Environment driver can now implement an init

env_init() now handles -ENOENT correct by setting the

This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.
Before this change it was necessary to use:
/* SPI Flash Configs */
#if defined(CONFIG_SPL_BUILD)
#undef CONFIG_DM_SPI
#undef CONFIG_DM_SPI_FLASH
#undef CONFIG_SPI_FLASH_MTD
#endif
in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.
The goal of this patch:
Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.
Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).
In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):
- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
environment with no fitImage and OF_LIBFDT support).
Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.
This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

Deciding whether to compile the env_sf_save() function based solely on
CONFIG_SPL_BUILD is wrong: For U-Boot proper, it leads to a build
warning in case CONFIG_CMD_SAVEENV=n (because the initialization of
the .save member is guarded by CONFIG_CMD_SAVEENV, while the
env_sf_save() function is built if !CONFIG_SPL_BUILD - and even
without the CONFIG_CMD_SAVEENV guard, the env_save_ptr() macro would
just expand to NULL, with no reference to env_sf_save visible to the
compiler). And for SPL, when one selects CONFIG_SPL_SAVEENV, one
obviously expects to actually be able to save the environment.
The compiler warning can be fixed by using a "<something> ?
env_sf_save : NULL" construction instead of a macro that just eats its
argument and expands to NULL. That way, if <something> is false,
env_sf_save gets eliminated as dead code, but the compiler still sees
the reference to it.
For <something>, we can use CONFIG_IS_ENABLED(SAVEENV), which is true
precisely:
- For U-Boot proper, when CONFIG_CMD_SAVEENV is set (because
CONFIG_SAVEENV is a hidden config symbol that gets set if and only
if CONFIG_CMD_SAVEENV is set).
- For SPL, when CONFIG_SPL_SAVEENV is set.
As a bonus, this also removes quite a few preprocessor conditionals.
This has been run-time tested on a mpc8309-derived board to verify
that saving the environment does indeed work in SPL with these patches

I'm also seeing the build failure that commit
7d4776545b env: solve compilation error in SPL
tried to fix, namely that the reference to env_flags_validate from
env_htab cannot be satisfied when flags.o is not built in. However,
that commit got reverted by
d90fc9c3de Revert "env: solve compilation error in SPL"
Necessary, but not sufficient conditions to see this are
CONFIG_SPL=y (obviously)
CONFIG_SPL_ENV_SUPPORT=n (so flags.o does not get compiled)
CONFIG_SPL_LIBCOMMON_SUPPORT=y (so env/built-in.o is part of the SPL link)
Now, these are satisfied for e.g. imx6q_logic_defconfig. But that
builds just fine, and spl/u-boot-spl.map lists .data.env_htab among
the discarded (garbage collected) sections. Yet, on our
mpc8309-derived board, we do see the build failure, so perhaps the
linker works a bit differently on ppc than on ARM, or there's yet some
other configuration option needed to observe the break.
This is another attempt at solving it, which also cleans up
env/Makefile a bit: Introduce a def_bool y symbol CONFIG_ENV_SUPPORT
which complements CONFIG_(SPL/TPL)_SUPPORT. Then use
CONFIG_$(SPL_TPL_)ENV_SUPPORT to decide whether to include the five
basic env/*.o files. For attr.o, flags.o and callback.o, this
shouldn't change anything. Also, common.o and env.o still get
unconditionally built for U-boot proper. But for TPL/SPL, those two
are only included if CONFIG_(SPL/TPL)_SUPPORT is set.
Having that symbol should also allow simplifying conditionals such as
#if !defined(CONFIG_SPL_BUILD) || CONFIG_IS_ENABLED(ENV_SUPPORT)
found in drivers/reset/reset-socfpga.c to just
CONFIG_IS_ENABLED(ENV_SUPPORT).

When booting using an SPL on am335x, if we want to support booting with
the boot ROM loader via USB (which uses RNDIS, making bootp and tftp
calls) we need to enable gadget eth in the SPL to load the main U-Boot
image. To enable CONFIG_SPL_ETH_SUPPORT, we must enable
CONFIG_SPL_ENV_SUPPORT as the environment is used by the eth support, but
we don't actually need to have environment variables saved in the SPL
environment. We do however have environment variables saved in the main
U-Boot image and enable CONFIG_ENV_OFFSET_REDUND (we are storing in raw
NAND). In such instances, even with the build config enabling both
CONFIG_CMD_SAVEENV and CONFIG_CMD_NAND, these options aren't set when
building the SPL, but CONFIG_ENV_OFFSET_REDUND still is.
Don't check this configuration option for SPL builds to enable the above
configuration.

In case when the environment on some location is malformed (CRC isn't
matching), there is a chance we won't be able to save the environment to
that location. For example, consider the case when we only have the
environment on eMMC, but it's zeroed out. In that case, we won't be able
to "env save" to it, because of "bad CRC" error. That's happening
because in env_load() function we consider malformed environment as
incorrect one, and defaulting to the location with highest (0)
priority, which can be different from one we are dealing with right now
(e.g., highest priority can be ENV_FAT on SD card, which is not
inserted, but we want to use ENV_MMC on eMMC, where we were booted
from).
This issue began to reproduce after commit d30ba2315a ("u-boot: remove
driver lookup loop from env_save()") on BeagleBone Black, but that
commit didn't introduce the wrong logic, it just changed the behavior
for default location to use, merely revealing this issue.
To fix that, let's implement next logic in env_load():
1. Try to find out correct environment; if found -- use it
2. If working environment wasn't found, but we found malformed one
(with bad CRC), let's use it for further "env save". But make sure
to use malformed environment location with highest priority.
3. If neither correct nor malformed environment was found, let's
default to environment location with highest priority (0)
Steps to reproduce mentioned issue on BeagleBone Black (fixed in this
patch):
1. Boot from SD card and erase eMMC in U-Boot shell:
=> mmc dev 1
=> mmc erase 0 100000
=> gpt write mmc 1 $partitions
2. Write new SPL and U-Boot to eMMC; the rest of eMMC will stay filled
with zeroes
3. Boot from eMMC; try to do:
=> env save
4. Observe the error (incorrect behavior). Correct behavior: environment
should be stored correctly on eMMC, in spite of it has "bad CRC"

Callers of env_import*() functions might want to check the case when we
have incorrect environment (with bad CRC). For example, when environment
location is being defined in env_load(), call chain may look like this:
env_load() -> drv->load() = env_mmc_load() -> env_import()
Return code will be passed from env_import() all way up to env_load().
Right now both env_mmc_load() and env_import() return -EIO error code,
so env_load() can't differentiate between two cases:
1. Driver reports the error, because device is not accessible
2. Device is actually accessible, but environment is broken
Let's return -ENOMSG in env_import(), so we can distinguish two cases
mentioned above. It will make it possible to continue working with "bad
CRC" environment (like doing "env save"), instead of considering it not
functional (implemented in subsequent patch).

The spi_flash_read_env function is a wrapper over spi_flash_read, which
enables the env to read multiple flash page size from flash until '\0\0'

The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.
Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
especially the H_FORCE flag from do_env_default() in nvedit.c that
currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
able to set flags without passing a string and vice versa.
Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.

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

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.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

Use CONFIG_IS_ENABLED to see if CONFIG_BLK is enabled. Otherwise
SPL compilation breaks on boards which do have CONFIG_BLK enabled but
not DM_MMC for the SPL as follows:

Modifying the default environment via CONFIG_EXTRA_ENV_SETTINGS is
somewhat inflexible, partly because the cpp language does not allow
appending to an existing macro. This prevents reuse of "environment
fragments" for different boards, which in turn makes maintaining that
environment consistently tedious and error-prone.
This implements a Kconfig option for allowing one to define the entire
default environment in an external file, which can then, for example, be
generated programmatically as part of a Yocto recipe, or simply be kept
in version control separately from the U-boot repository.

Commit 7653942b10 ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.
This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:
04003df8 g F .text 00000038 mii_init
04004000 g O .text 00000004 env_size
04004004 g O .text 00002000 environment
04006004 g F .text 00000040 .hidden __lshrdi3
This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:
. = DEFINED(env_offset) ? env_offset : .;
env/embedded.o (.text.environment)

Since the dawn of time for the Allwinner support in mainline U-Boot
we store the environment to the SD card and write directly at
544KB from the beginning of the device. This leads to problems when
the U-Boot proper image grows beyond 504KB and eventually overlaps.
With one release of having the environment preferably in a FAT
partition, let's now turn off the MMC variant fallback, so we get back
all the space we need to implement features.

Introduce another difference from upstream (kernel) source in
fs/ubifs/super.c: adding preprocessor condition as y variable in
mount_ubifs() depends on CONFIG_UBIFS_SILENCE_MSG:

long long x, y;
Not setting CONFIG_UBIFS_SILENCE_MSG in am335x_igep003x_defconfig and
igep0032_defconfig. Although it was defined in their config headers, it
depends on CMD_UBIFS which is not set for them.
