d1ca61ca7e env: Improve ENV_OFFSET help message
When reading Kconfig help messages to understand ENV_OFFSET and
ENV_OFFSET_REDUND, developers may not realise that they need to also
look at the chosen ENV_IS_IN_* options to see how the offsets will be
interpreted.

a077ac13d0 Kconfigs: Correct default of "0" on hex type entries
It is not a parse error to have a default value of "0" for a "hex" type
entry, instead of "0x0".  However, "0" and "0x0" are not treated the
same even by the tools themselves. Correct this by changing the default
value from "0" to "0x0" for all hex type questions that had the
incorrect default. Fix one instance (in two configs) of a default of "0"
being used on a hex question to be "0x0". Remove the cases where a
defconfig had set a value of "0x0" to be used as the default had been
"0".

9e70676cf5 env: mmc: statically set the environment partition name
The new opt-out setting, CONFIG_ENV_MMC_PARTITION, statically sets
the MMC environment partition name. Prior to this patch, the only way
to declare this partition name was by creating a
'u-boot,mmc-env-partition' parameter in the device-tree's /config node.

This setting provides additional flexibility, particularly in cases
where accessing the device-tree is not straightforward (e.g. QEMU).

If undeclared, the device-tree's setting will be used.

This completes what 890feecaab started by selecting ENV_APPEND and
loading the default env before any other sources. This ensures that load

With this change, boards only need to define the list of writable

This patch avoids issues when several CONFIG_ENV_IS_IN_XXX are activated,

ce8808628e xilinx: Add env redund offset
ENV_OFFSET_REDUND config is by default set to 0 for flashes. Saving the env
variables is overwriting data at 0 offset, which is wrong. So add default
redund env offset for Zynq, ZynqMP, Versal and microblaze platforms.
Configured ENV_OFFSET_REDUND offsets by ENV_OFFSET + (2 * ENV_SIZE).

In case of versal, we configured ENV_OFFSET_REDUND at 0x7F00000 instead
of 0x7F80000. As BOOT_SCRIPT_OFFSET is already configured at 0x7F80000.

Added ENV_OFFSET_REDUND in Kconfig for microblaze due to dependency of
ENV_IS_IN_SPI_FLASH config.

Below table specifies platform specific env and env redund offsets.

PLAT		ENV_OFFSET	ENV_OFFSET_REDUND
----		----------	-----------------
ZYNQ		0xE0000		0xE40000

Now that sunxi uses CONFIG_SPI more sanely, and can also now properly
load the environment from SPI flash, let's enable the symbol that
actually considers the SPI flash when accessing the environment.

As this symbol depends on CONFIG_SPI, which we now only enable if the
board has a SPI flash, we can make if "default y" for all Allwinner
boards.

2bdf213f91 env: sunxi: Define location in SPI flash
To allow loading and storing the environment from SPI flash, adjust the
raw offset variables for Allwinner boards to make sense there.

U-Boot (including SPL and other blobs) is loaded from the beginning of
SPI flash, so move the environment location as far back as possible, to
not create unnecessary limits. As those offsets are shared with (now
mostly unused) raw MMC environment, we should respect the common one
megabyte limit, which also makes sense on SPI flash.

So limit the environment for those raw locations to 64KB, and place it
just below 1MB (@960KB).

Those values are currently unused, unless someone forcibly enables the
raw MMC environment. In this case it would break as of now, as the
current offset of 544KB is far too low for the current (arm64) U-Boot
proper.

86b9c3e4e4 env: Allow U-Boot scripts to be placed in a .env file
At present U-Boot environment variables, and thus scripts, are defined
by CONFIG_EXTRA_ENV_SETTINGS. It is painful to add large amounts of text
to this file and dealing with quoting and newlines is harder than it
should be. It would be better if we could just type the script into a
text file and have it included by U-Boot.

Add a feature that brings in a .env file associated with the board
config, if present. To use it, create a file in a board/<vendor>
directory, typically called <board>.env and controlled by the
CONFIG_ENV_SOURCE_FILE option.

The environment variables should be of the form "var=value". Values can
extend to multiple lines. See the README under 'Environment Variables:'
for more information and an example.

In many cases environment variables need access to the U-Boot CONFIG
variables to select different options. Enable this so that the environment
scripts can be as useful as the ones currently in the board config files.
This uses the C preprocessor, means that comments can be included in the
environment using /* ... */

Also support += to allow variables to be appended to. This is needed when
using the preprocessor.

d11d1becbd env: mmc: Add support for redundant env in both eMMC boot partitions
Currently the MMC environment driver supports storing redundant environment
only in one eMMC partition at different offsets. This is sub-optimal, since
if this one boot partition is erased, both copies of environment are lost.
Since the eMMC has two boot partitions, add support for storing one copy of
environment in each of the two boot partitions.

To enable this functionality, select CONFIG_SYS_REDUNDAND_ENVIRONMENT to
indicate redundant environment should be used. Set CONFIG_SYS_MMC_ENV_PART
to 1 to indicate environment should be stored in eMMC boot partition. Set
CONFIG_ENV_OFFSET equal to CONFIG_ENV_OFFSET_REDUND, and both to the offset
from start of eMMC boot partition where the environment should be located.

95fd977201 env: allow environment to be amended from control dtb
It can be useful to use the same U-Boot binary for multiple purposes,
say the normal one, one for developers that allow breaking into the
U-Boot shell, and one for use during bootstrapping which runs a
special-purpose bootcmd. Or one can have several board variants that
can share almost all boot logic, but just needs a few tweaks in the
variables used by the boot script.

To that end, allow the control dtb to contain a /config/enviroment
node (or whatever one puts in fdt_env_path variable), whose
property/value pairs are used to update the run-time environment after
it has been loaded from its persistent location.

The indirection via fdt_env_path is for maximum flexibility - for
example, should the user wish (or board logic dictate) that the values
in the DTB should no longer be applied, one simply needs to delete the
fdt_env_path variable; that can even be done automatically by
including a

  fdt_env_path = "";

property in the DTB node.

bcb44f62b2 env: add CONFIG_ENV_SECT_SIZE_AUTO
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.

That's why also for this configuration make sense to enable

format.

b0493bb75a env/ext4.c: allow loading from an EXT4 partition on the MMC boot device
This parallels what I added for FAT in commit 6731bef696, allowing the
environment to be found in a specific partition on the device that the
board's mmc_get_env_dev() returns. On the Banana Pi R2 that means the
device that U-Boot was loaded from; either the internal eMMC or an SD
card.

7d08077334 Convert CONFIG_SYS_MMC_ENV_DEV et al to Kconfig
This converts the following to Kconfig:
   CONFIG_SYS_MMC_ENV_DEV
   CONFIG_SYS_MMC_ENV_PART

Note that with this conversion we now have consistent behavior with
respect to ensuring that we have always selected the correct MMC
device and hardware partition.

d045cbacf2 env: Add support for explicit write access list
This option marks any U-Boot variable which does not have explicit 'w'
writeable flag set as read-only. This way the environment can be locked
down and only variables explicitly configured to be writeable can ever
be changed by either 'env import', 'env set' or loading user environment
from environment storage.

47f3b1f243 env: Add option to only ever append environment
Add configuration option which prevents the environment hash table to be
ever cleared and reloaded with different content. This is useful in case
the first environment loaded into the hash table contains e.g. sensitive
content which must not be dropped or reloaded.
