0417b8523c blk: Hide the BLK and SPL_LEGACY_BLOCK options
We don't want boards to be able to change these. They can be handled
as dependencies of options that need them, such as SPL_MMC. There is no
point in enabling the block interface without any storage devices to
create a block device.

Hide both options from the 'menuconfig' display and deny their use in
defconfig files.

7f8967c2b8 blk: Rename HAVE_BLOCK_DEVICE
This option is fact really related to SPL. For U-Boot proper we always use
driver model for block devices, so CONFIG_BLK is enabled if block devices
are in use.

It is only for SPL that we have two cases:

- SPL_BLK is enabled, in which case we use driver model and blk-uclass.c
- SPL_BLK is not enabled, in which case (if we need block devices) we must
  use blk_legacy.c

Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is
different enough from BLK and SPL_BLK that there should be no confusion.

003357cc48 cmd: Drop use of HAVE_BLOCK_DEVICE
This condition is not needed for these commands, since BLK is enabled for
all boards which use block devices and commands are not available in SPL,

a51eb8de31 blk: Use a function for whether block devices are available
At present we use HAVE_BLOCK_DEVICE to indicate when block devices are
available.

This is a very strange option, since it partially duplicates the BLK
option used by driver model. It also covers both U-Boot proper and SPL,
even though one might have block devices and another not.

As a first step towards correcting this, create a new inline function
called blk_enabled() which indicates if block devices are available.
This cannot be used in Makefiles, or #if clauses, but can be used in C
code.

A function is useful because we cannot use CONFIG_IS_ENABLED(BLK) to
decide if block devices are needed, since we must consider the legacy
block interface, enabled by HAVE_BLOCK_DEVICE

Update a few places where it can be used and drop some unnecessary #if
checks around some functions in disk/part.c - rely on the compiler's
dead-code elimination instead.

At present these files have an #ifdef covering the whole file. Move the

Add BLK to the condition since future patches will adjust things so that
HAVE_BLOCK_DEVICE is only for SPL, but the partition drivers are needed

Commit 0ea4fc4dcf ("board/BuR: invalidate ${dtbaddr} before cfgscr")
destroys the boot targets b_t30lgcy#0 and b_t30lgcy#1. The reason behind
this is, that b_t30lgcy#0 and b_t30lgcy#1 both load the for booting
needed device trees from mmc and the cfgscr script patches those. Because
of this, cfgscr is not allowed to destroy the previously loaded device
tree otherwise cfgscr will fail.
This patch moves the device trees invalidation on warm restart to the
PREBOOT cmd to fix that issue.

b0a18f1f9f brppt1: Fix SPL boot stage
Commit 6337d53fdf ("arm: dts: sync am33xx with Linux 5.9-rc7") syncs
the am335x device tree with the latest linux kernel am335x device tree.
That causes problems with device tree in SPL stage.
To fix the issues CONFIG_SPL_OF_TRANSLATE must be set to handle the
synced bus addresses correctly.
A custom U-Boot device tree is also needed since the SPL build removes
bus properties from bus nodes which are not explicitly marked with the
u-boot,dm-spl or u-boot,dm-pre-reloc flag. Therefore all parent buses of
the in the SPL needed devices must be marked with u-boot,dm-pre-reloc.
Also since there is no driver for "ti,sysc" compatible property in SPL
the buses marked with this compatible string must also be marked with
compatible = "simple-bus" to make the underlying devices visible in
SPL. Otherwise the matching device drivers aren't found and the uclass
drivers are dropped.

This potentially can lead to the illegal creation of pages on

that splitting the prp-list into multiple pages, behaves now as
required by the NVME-Spec.

infinite timeout. Default value is 90s which is the value used before this
change for loadx command.

Other load commands loadb and loads already waits infinitely. Same behavior
for loadx and loady commands can be achieved by setting $loadxy_timeout or
CONFIG_CMD_LOADXY_TIMEOUT to 0.

3bf699f7a8 i2c: stm32: do not set the STOP condition on error
Current function stm32_i2c_message_xfer is sending a STOP
whatever the result of the transaction is.  This can cause issues
such as making the bus busy since the controller itself is already
sending automatically a STOP when a NACK is generated.

Thanks to Jorge Ramirez-Ortiz for diagnosing and proposing a first
fix for this. [1]

bcc7509265 i2c: stm32: remove unused stop parameter in start & reload handling
Functions stm32_i2c_message_start and stm32_i2c_handle_reload
both get a stop boolean indicating if the transfer should end with
a STOP or not.  However no specific handling is needed in those
functions hence remove the parameter.
