e48ec51b43 spi: stm32_qspi: Add WATCHDOG_RESET in _stm32_qspi_read_fifo()
In case of reading large area and memory-map mode is misconfigured
(memory-map size declared lower than the real size of the memory chip)
watchdog can be triggered.

Add WATCHDOG_RESET() in _stm32_qspi_read_fifo to fix it.

Issue reproduced with stm32mp157c-ev1 board and memory map size set to
1, with following command:
sf read 0xC0000000 0 0x4000000

162f5888e7 spi: stm32_qspi: migrate trace to dev and log macro
Change debug/pr_* to log_* or dev_* macro and define LOG_CATEGORY.

Remove the "%s:" __func__  header as it is managed by dev macro
(dev->name is displayed) or log macro (CONFIG_LOGF_FUNC).

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
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
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

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.

321d153238 spi: stm32_qspi: move to exec_op
We are facing issues in the driver since SPI NOR framework has moved
on SPI MEM framework, and SPI NAND framework is not running properly
with the current driver.

To be able to solve issues met on SPI NOR Flashes and to be able to
support SPI NAND Flashes, the driver has been reworked. We are now using
exec_op ops instead of using xfer ops.

Thanks to this rework, the driver has been successfully tested with:
 - mx66l51235l SPI NOR Flash on stm32f746 SOC
 - n25q128a SPI NOR Flash on stm32f769 SOC
 - mx66l51235l SPI NOR Flash on stm32mp1 SOC
 - mt29f2g01abagd SPI NAND Flash on stm32mp1 SOC

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
