bdf8fd76c0 dm: Rename U_BOOT_DRIVER_ALIAS to DM_DRIVER_ALIAS
We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but
in every other case we just use DM_. Update the alias macros to use the
DM_ prefix.

We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro
is widely used and there is at least some benefit to indicating it us a
U-Boot driver, particularly for code ported from Linux. So for now, let's
keep that name.

a1a8a63385 spi: Tweak a few strange SPI NOR features for of-platdata
The #define of one struct to another has been around for a while. It
confuses dtoc and makes it think that struct spi_flash does not exist.

Make a few changes to improve things while we wait for migration to be
completed:

- Move the 'struct spi_flash' to column 1 so dtoc scans it
- Remove the #define when compiling dt-platdata.c
- Update the strange mtd_get/set_of_node() functions
- Use struct spi_nor in the drivers, so dtoc sees the correct struct

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces

Coincidentally it also ensures that every declaration is on one line,

addf358bac core: add support for U_BOOT_DRIVER_ALIAS
Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.

To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

e3e2470fdd drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

56c4046038 spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*
This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.

Before this change it was necessary to use:
    /* SPI Flash Configs */
    #if defined(CONFIG_SPL_BUILD)
    #undef CONFIG_DM_SPI
    #undef CONFIG_DM_SPI_FLASH
    #undef CONFIG_SPI_FLASH_MTD
    #endif

in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.

The goal of this patch:

Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.

Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).

In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):

- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
  run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
  environment with no fitImage and OF_LIBFDT support).

Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.

This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

f12f96cfaf sf: Drop spl_flash_get_sw_write_prot
The get_sw_write_prot API is used to get the write-protected
bits of flash by reading the status register and other wards
it's API for reading register bits.

1) This kind of requirement can be achieved using existing
   flash operations and flash locking API calls instead of
   making a separate flash API.
2) Technically there is no real hardware user for this API to
   use in the source tree.
3) Having a flash operations API for simple register read bits
   also make difficult to extend the flash operations.
4) Instead of touching generic code, it is possible to have
   this functionality inside spinor operations in the form of
   flash hooks or fixups for associated flash chips.

Considering all these points, this patch drops the get_sw_write_prot
and associated code bases.

Enable QE bit for ISSI flash chips.

QE enablement logic is similar to what Macronix
has, so reuse the existing code itself.

6f3b1f4a1d mtd: spi-nor: Enable dual and quad read for s25fl256s0
The s25fl256s0 supports dual and quad read like s25fl256s1.
Enable it by adding SPI_NOR_DUAL_READ and SPI_NOR_QUAD_READ
flags to the flash_info entry.
Tested on real silicon and confirmed to be working.

cae3c7cc58 mtd: spi-nor-ids: Enable SPI_NOR_OCTAL_READ flag for mt35xu*
Commit 658df8bd94 ("mtd: spi-nor-core: Add octal mode support")
enables octal mode(1-1-8) support in spi-nor framework.

mt35xu512aba and mt35xu02g supports SINGLE and OCTAL I/O. Hence, enable
SPI_NOR_OCTAL_READ flag for these flashes.

7ddea75654 spi: use is_power_of_2 instead of hweight32 in spi_nor_write()
hweight32 is a somewhat expensive way to check for power-of-2. Use the
is_power_of_2 helper, which does the standard and cheap idiom
foo&(foo-1)==0.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

61b29b8268 dm: core: Require users of devres to include the header
At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.
