Apply the GPT U-Boot environment GUID type look up only on eMMC user
HW partition, do not apply the look up on eMMC boot HW partitions as
mmc_offset_try_partition() assumes either SD partitions or eMMC user
HW partition.
This fixes environment operation on systems where CONFIG_SYS_MMC_ENV_PART
is non-zero and CONFIG_SYS_REDUNDAND_ENVIRONMENT is set.
Fixes: 80105d8fd52 ("env: mmc: select GPT env partition by type guid")

This completes what 890feecaab72 started by selecting ENV_APPEND and
loading the default env before any other sources. This ensures that load
operations pick up all non-writable vars from the default env and only
permitted parts from other locations according to the regular
priorities.
With this change, boards only need to define the list of writable
variables but no longer have to provide a custom env_get_location
implementation.

This patch introduces a local define ENV_UBI_VOLUME_REDUND

Since commit c0364ce1c695 ("doc/README.gpt: define partition type GUID for

This patch uses this type GUID to found the env partition as fallback
when the partition name property "u-boot,mmc-env-partition" is not present
in config node or if the indicated partition name is not found.

means ENV_IS_EMBEDDED, so reference that in code and rename the Makefile

- Remove extra-$(CONFIG_ENV_IS_EMBEDDED) line as it could never be true,
and likely why there is an extra- line for CONFIG_ENV_IS_IN_FLASH (the
only use case today of embedded environments).
- With these slight changes we can then see that using the calculated

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.

On eMMC device, the erase_grp_size > 1 so the address and size for the
erase block command in env/mmc.c can be unaligned on erase group size and
some strange trace occurs and the result is not guarantee by MMC devices.
The SD-Card behavior doesn't change as erase_grp_size = 1 for SD-Card.
For example, on eMMC present on STM32MP15C-EV1 and before the patch:
STM32MP> env erase

Caution! Your devices Erase group is 0x400
The erase range would be change to 0x2000~0x27ff

Caution! Your devices Erase group is 0x400

Now, spi_flash_probe_bus_cs() relies on DT for spi speed and mode
and logically calls spi_get_bus_and_cs(). In case spi mode and speed are
not read from DT, make usage of spi_flash_probe() instead.
To sum-up:
- Previous call tree was:
spi_flash_probe() -> spi_flash_probe_bus_cs() -> spi_get_bus_and_cs()
- Current call tree is:
spi_flash_probe() -> _spi_get_bus_and_cs()
spi_flash_probe_bus_cs() -> spi_get_bus_and_cs()
This patch impacts the following :
- cmd/sf.c: if spi mode and/or speed is passed in argument of
do_spi_flash_probe(), call spi_flash_probe() otherwise call
spi_flash_probe_bus_cs().
- drivers/net/fm/fm.c: as by default spi speed and mode was set to
0 and a comment indicates that speed and mode are read from DT,
use spi_flash_probe_bus_cs().
- drivers/net/pfe_eth/pfe_firmware.c: spi speed and mode are not read
from DT by all platforms using this driver, so keep legacy and replace
spi_flash_probe_bus_cs() by spi_flash_probe();
- drivers/net/sni_netsec.c : spi speed and mode are not read from DT,
so replace spi_flash_probe_bus_cs() by spi_flash_probe().
- drivers/usb/gadget/max3420_udc.c: Can't find any platform which make
usage of this driver, nevertheless, keep legacy and replace
spi_get_bus_and_cs() by _spi_get_bus_and_cs().
- env/sf.c: a comment indicates that speed and mode are read
from DT. So use spi_flash_probe_bus_cs().

Allow it for boards by providing custom implementation of weak function

Currently there is only one way to override desired environment location,
by implementing env_get_location(). This is increasingly being conflated
both on board level and architecture level, which leads to a problem on
boards where this function is already implemented on architecture level,
since those boards have no way to override this environment location on
board level anymore.
Implement arch_env_get_location() function which is architecture specific
and should only ever be implemented in architecture code. This function
has lower priority than env_get_location(), which should only ever be
implemented in board code, and which overrides the arch_env_get_location()
architecture environment selection.
This way, architecture can define its default environment chooser, while
board can now override it as needed at all times.
There is no functional change, since env_get_location() simply returns
arch_env_get_location(), and arch_env_get_location() implements the
current env_get_location() default content.

This reverts commit 8d61237edbf6314a701cf78da2c5893a73ff5438.
This commit broke environment on literally every board I have access
to, with this revert in place, environment works as it should again.
The problem I observe with this patch is that saved environment in
either SPI NOR or eMMC is never used, the system always falls back
to default environment. The 'saveenv' command does succeed, but then
after reset, the default env is again used.
Furthermore, the commit introduced duplicate code in env_init(), this:
"
if (!prio) {
gd->env_addr = (ulong)&default_environment[0];
gd->env_valid = ENV_INVALID;
return 0;
}
if (ret == -ENOENT) {
gd->env_addr = (ulong)&default_environment[0];
gd->env_valid = ENV_INVALID;
return 0;
}
"
Furthermore, the commit is missing DCO SoB line.
Also note that upstream does not support UltraZed EG board, so
this might have been a patch pulled from downstream which did
depend on some other downstream behavior.

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.

This has different semantics in different places. Go with the bootm method
and put it in a common function so that the behaviour is consistent in
U-Boot. Update the docs.
To be clear, this changes the way that 'bootelf' and standalone boot
work. Before, if autostart was set to "fred" or "YES", for example, they
would consider that a "yes". This may change behaviour for some boards,
but the only in-tree boards which mention autostart use "no" to disable
it, which will still work.

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.
