de70e8879b env: Implement lower priority arch_env_get_location()
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.

5c7399ec90 Revert "env: Load env when ENV_IS_NOWHERE is only location selected"
This reverts commit 8d61237edb.

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.

8d61237edb env: Load env when ENV_IS_NOWHERE is only location selected
This patch prevent u-boot from hanging on a UltraZed EG board (zynqmp).

Without the patch,
(drv = env_driver_lookup(ENVOP_INIT, prio))
evaluates to 0, causing prio = 0
Then, (!prio) is hit, returning -ENODEV causing a stall.

With the patch,
instead of returning -ENODEV and causing a stall, we
set gd->env_addr (is this really needed?)
and then
mark gd->env_valid = ENV_INVALID to use the default env.

753a85fd15 env: sunxi: enable ENV_IS_IN_SPI_FLASH
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.

7839865272 bootm: Tidy up use of autostart env var
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.

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.

The 'env erase' implementation in the MMC environment driver lacks the path
which restores the boot partition. This could lead to various failure modes,
like the system boots the wrong copy of bootloader etc. Fix this by filling
in the missing restoration path.

All supplied callback methods in U-Boot do nothing, but the

in U-Boot's mtdpart implementation for completely different purpose.

Since we got rid of the abusement, remove the mtd_erase_callback()
function and the .callback member from struct erase_info entirely, in

f6bc5d17af env: Make _init() expect _INVALID when _IS_NOWHERE
Avoid applying the "fix" introduced by commit 5557eec01c ("env: Fix
invalid env handling in env_init()") to the environment "nowhere".

This is necessary as that commit, by setting the return value of
env_init() to -ENOENT if gd->env_valid is ENV_INVALID, forces that
function to reset gd->env_valid to ENV_VALID. By doing so, it breaks the
assumption (required by ENV_IS_NOWHERE) that gd->env_valid must be
ENV_INVALID.

This, in turn, results in env_relocate() calling env_load() (it should
not), which itself, calls U_BOOT_ENV_LOCATION(nowhere).load() i.e.
env_nowhere_load(). That function, being implemented under the
assumption mentioned above, calls env_set_default(), which in turn,
seeing that gd->env_valid is ENV_VALID (it should not), tries to
dereference whatever lies in gd->env_addr (most likely garbage), leading
to a faulty memory access.

Note that other env_locations might be concerned by this bug but that
this commit only intends to fix it for when ENV_IS_NOWHERE.

- Rename usages of CONFIG_SYS_DEF_EEPROM_ADDR to CONFIG_SYS_I2C_EEPROM_ADDR
  based on current usage.
- Convert CONFIG_SYS_I2C_EEPROM_ADDR, CONFIG_SYS_I2C_EEPROM_ADDR_LEN,
  CONFIG_SYS_I2C_EEPROM_BUS, CONFIG_CONFIG_SYS_EEPROM_SIZE
  CONFIG_SYS_EEPROM_PAGE_WRITE_BITS and CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS
  to Kconfig.  We move these symbols around a bit and add appropriate
  dependencies to them.  In some cases, we now add a correct default value
  as well.

c18afbe0ab eeprom: Drop CONFIG_ENV_EEPROM_IS_ON_I2C usage
At this point in time, there's no systems with "U-Boot environment
exists on an EEPROM which is accessed over the I2C bus" that sets this
option.  Drop it.

9b90e0d08f env: Kconfig: Add default option for PHY_CORTINA
Add PHY_CORTINA as default option in SYS_MMC_ENV_DEV Kconfig entry as
PHY_CORTINA require SYS_MMC_ENV_DEV value similar to FMAN_ENET or QE.
This helps in resolving compilation failure.

1011ebc72b sunxi: Select environment MMC based on boot device
Currently, the environment is always stored in eMMC if eMMC is enabled
in the config. This means images written to SD and eMMC will cross-
contaminate their environments unless the configuration is changed.

By dropping the device number from the environment location string and
implementing mmc_get_env_dev, we will always use the environment from
the boot device when booting from SD/eMMC.

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.
