There are two spi drivers for en7523/an7581/an7583:
* en7581-snand (spi-airoha-snfi.c)
* en7523-spi (spi-en7523.c)
The first one supports DMA, but until recently it has several nasty
issues. The second do things properly but does not support DMA.
Recently the first driver was greatly improved, so there is no sence
keep both drivers anymore.
This patch removes en7523-spi driver and use DMA capable driver instead.
Unfortunately there is a nasty en7523 specific issue.
We found that some serial console may pull TX line to GROUND during board
boot time. Airoha uses TX line as one of it's BOOT pins. This will lead
to booting in RESERVED boot mode. It was found that some flashes operates
incorrectly in RESERVED mode if DMA used.
This patch also adds a hack that turns off DMA and prints big fat warning
if booting in reserved mode was detected. This slow down flash operations
but does not kill your data.

This patch series removes dirty hack that reads flash page settings from
SNFI registers during driver startup.
Before these patches the airoha spi snfi driver needs to know spinand
flash page size. The driver can't get it from spinand subsystem, so the
following approach was implemented:
* bootloader know the flash page size (and some other parameters)
* to operate properly the bootloader writes flash page size (and some
other parameters) to SNFI registers
* bootloader starts linux
* after linux start SNFI registers keeps the values stored by bootloader
* linux snfi driver reads flash parameters from SNFI registers.
This works, but we can do better. It has been proven that flash page size
is actually unnecessary. We can get all required data from dirmap requests.
This patch series drops the hack and do things properly.

This patch series greatly improve airoha snfi driver and fix a
number of serious bugs.
Fixed bugs:
* Fix reading/writing of flashes with more than one plane per lun
* Fill the buffer with 0xff before writing
* Fix reading of flashes supporting continuous reading mode
* Fix error paths
Improvements:
* Add support of dual/quad wires spi modes in exec_op(). This also
fix flash reading/writing if dirmap can't be created.
* Support of dualio/quadio flash reading commands

Continuous reading mode is broken for some spi controllers. There are two
possible bug scenarios:
1) "continuous mode" flash and spi controller without dirmap support,
but with restriction on transfer length in adjust_op_size()
2) "continuous mode" flash and spi controller with dirmap support for a
single flash page
In the first case, any read that exceeds the limit specified in adjust_op_size()
will result in an EIO error. The limit may even be less than a size of a single
flash page. In this case, any read will result in an error.
In the second case, any read larger than flash page size will result in an EIO
error or spinand driver spoofing (because the spi controller driver returns
more bytes than were actually read).
This patch series tries to fix continuous reading (spinand driver side).
Unfortunately these fixes can't resolve "spinand driver spoofing" case.
Spi controller drivers might need fixes as well.

Introduce initial support for Airoha AN7583 SoC and add all the required
patch for basic functionality of the SoC.
Airoha AN7583 is based on Airoha EN7581 SoC with some major changes on
the PHY handling and Serdes. It can be see as a lower spec of EN7581
with modern and simplified implementations.
All the patch are sent upstream and are pending revision. Support for
PCIe and USB will come later as soon as DT structure is accepted
upstream.
