a246e21351 arm64: dts: meson: odroidc2: readd PHY reset properties
The sync of the device tree and dt-bindings from Linux v5.6-rc2
11a48a5a18c6 ("Linux 5.6-rc2") causes Ethernet to break on some
ODROID-C2. The PHY seems to need proper reset timing to be functional
in U-Boot and Linux afterwards. Readd the old PHY reset bindings for
dwmac until we support the new bindings in the PHY node.

c6ae5e9869 Merge https://source.denx.de/u-boot/custodians/u-boot-usb
This is a patchset which makes away with the .bind() controller indexing
workaround which was broken since before v2021.04, and then adds PHY
support and MX8M support on top of that. Better add it into the release
early to get as much testing as possible done, because this really does
a lot of changes to the ehci-mx6 driver.

ef464e4c36 usb: ehci-mx6: Split ehci_mx6_common_init()
In order to pass component addresses around easily instead of passing
ad-hoc sequence numbers, it is necessary to split ehci_mx6_common_init().
Make it so and call the separate functions instead.

Since board_ehci_hcd_init() makes no sense in DM case, do not call it
in DM case.

7d823747c6 efi_loader: esrt: Remove incorrect invocations of EFI_CALL macro
Remove function invocations using the EFI_CALL macro for those
functions that do not have an EFI_ENTRY call in their definition. Such
functions can use u-boot api's which rely on u-boot global data(gd)
pointer. The Arm and RiscV architectures maintain a separate gd
pointer, one for u-boot, and a separate gd for the efi application.

Calling a function through the EFI_CALL macro changes the gd pointer
to that used for the efi application, with u-boot gd being
unavailable. Any function then trying to dereference u-boot's gd will
result in an abort.

Fix this issue by removing the EFI_CALL macro for all of such
functions which do not begin by an EFI_ENTRY function call.

ecf1544232 env: sf: remove the static env_flash variable
As the the SPI flash is probed and is released in each ENV sf function
the env_flash no more need to be static.

This patch move this device handle as local variable of each function and
simplify the associated code (env_flash is never == NULL when
setup_flash_device is called).

25d90ad45a env: sf: add support of command env erase
Add support of opts erase for env in SPI flash;
this opts is used by command 'env erase'.

This command only fills the env offset by 0x0 (bit flip to 0) and
the saved environment becomes invalid (with bad CRC).

It doesn't erase the sector here to avoid issue when the sector
is larger than the env (i.e. embedded when
CONFIG_ENV_SECT_SIZE > CONFIG_ENV_SIZE).

The needed sector erase will be managed in the next "env save" command,
using the opt ".save", before to update the environment in SPI flash.

5557eec01c env: Fix invalid env handling in env_init()
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.

9636bf8b2e env: Fix warning when forcing environment without ENV_ACCESS_IGNORE_FORCE
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
	}

Fixes: 0f036bf4b8 ("env: Warn on force access if ENV_ACCESS_IGNORE_FORCE set")

b9c3052fbb env: increment redund flag on read fail
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.

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.
