This series adds significant and valuable work by Mikhail Kshevetskiy to align spi-mem with Linux 6.16. It also includes contributions to the mtd performance patches, a work started by Miquel Raynal and improved by Mikhail Kshevetskiy. Additionally, two patches tighten dependencies on the Atmel driver. The patches pass the pipeline CI: https://source.denx.de/u-boot/custodians/u-boot-nand-flash/-/pipelines/27873

These devices provide Memory bus interface to various devices like
|
|
SRAM, Ethernet adapters, FPGAs, etc.

This driver manages the muxing between the 2 OSPI busses and
|
|
the 2 output ports. There are 4 possible muxing configurations:
|
|
- direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2
|
|
output is on port 2
|
|
- OSPI1 and OSPI2 are multiplexed over the same output port 1
|
|
- swapped mode (no multiplexing), OSPI1 output is on port 2,
|
|
OSPI2 output is on port 1
|
|
- OSPI1 and OSPI2 are multiplexed over the same output port 2
|
|
It also manages :
|
|
- the split of the memory area shared between the 2 OSPI instances.
|
|
- chip select selection override.
|
|
- the time between 2 transactions in multiplexed mode.

This driver is for the AEMIF module available in Texas Instruments
|
|
SoCs. AEMIF stands for Asynchronous External Memory Interface and
|
|
is intended to provide a glue-less interface to a variety of
|
|
asynchronuous memory devices like ASRAM, NOR and NAND memory. A total
|
|
of 256M bytes of any of these memories can be accessed at a given
|

time via four chip selects with 64M byte access per chip select.
