Merge branch '2022-09-16-rationalize-the-block-interface' into next
The block interface has two separate implementations, one using driver
model and one not. The latter is really only needed for SPL, where
size constraints allegedly don't allow use of driver model. Of course
we still need space for filesystems and other code, so it isn't clear
that driver model is anything more than the straw that breaks the
camel's back.
The driver model version uses a uclass ID for the interface time, but
converts back and forth between that and if_type, which is the legacy
type.
The HAVE_BLOCK_DEVICE define is mostly a hangover from the old days.
At present its main purpose is to enable the legacy block implementation
in SPL.
Finally the use of 'select' to enable BLK does not work very well. It
causes kconfig errors when another option depends on BLK and it is
not recommended by the kconfig style guide.
This series aims to clean things up:
- Enable BLK based on whether different media types are used, but still
allow boards to disable it
- Rename HAVE_BLOCK_DEVICE to indicates its real purpose
- Drop if_type and use the uclass instead
- Drop some obsolete if_type values
An issue not resolved by this series is that the sandbox host interface
does not actually have a device. At present it uses the root device, which
was convenience for the driver model conversion but not really correct. It
should be possible to clean this up, in a future series.
Another minor issue is the use of UCLASS_USB for a mass-storage device.
This has been the case for a while and is not addresed by this series,
other than to add a comment.
Note that this test relies on Tom Rini's series to drop various boards
including warp and cm_t335
Finally, a patch is included to make binman put fake files in a
subdirectory, since repeated runs of certain boards can cause unrelated
failues (e.g. chromebook_coral) when fake files are left around.

- 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

blk: Use a function for whether 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.

Merge branch '2022-09-13-add-aspeed-spi-controller' into next
To quote the author:
This patch series aims to porting ASPEED FMC/SPI memory controller
driver with spi-mem interface. spi-mem dirmap framework is also
synchronized from Linux. These patches have been verified on
AST2600, AST2500 and AST2400 EVBs.

spi: aspeed: Clock frequency adjustment support
Driver can configure the SPI clock frequnecy to the
target value of "spi-max-frequency" property in
the device tree. The frequency is divided from HCLK,
200MHz. Usually, the ASPEED SPI clock frequency range
is between 12.5MHz and 100MHz. On AST2600, the lowest
SPI clock frequency can be about 780kHz.

spi: aspeed: Support customized decoded address ranges
If "decoded-ranges" is defined in the device tree, the
driver will apply the decoded address ranges from this
property to the controller during probe stage.
This patch refers to the following OpenBMC u-boot patch.

spi: aspeed: Adjust decoded range size support
There are some known HW problems about decoded
range register configurations on existing AST2500 and
AST2600 platforms. Additional callback function,
adjust_decoded_sz, is added to solve these problems
on each platform. Besides, aspeed_spi_trim_decoded_size
function is added to modify overall decoded address
size for fitting the maximum AHB decoded size.
