a073d3d37c Merge patch series "am65-cpsw-nuss phy_interface_t fixup for fixed TX delay"
Matthias Schiffer <matthias.schiffer@ew.tq-group.com> says:

Following a discussion on the LKML [1], there has been a clarification
of the correct use of the rgmii(/-rxid/-txid/-it) phy-modes [2] - namely,
that they don't describe the interface at the MAC or PHY boundary, but
whether the PCB traces add delays or not (where it is
implementation-defined whether the delays are added on the MAC or PHY
side in the latter case).

Accordingly, a fixup has been implemented in the am65-cpsw-nuss driver
to make it follow the clarified rules [3]; apply the same change to
U-Boot. Backwards compatibility is preserved: using an old DTB with
the wrong phy-mode only results in a warning message, but keeps the
Ethernet working. With a new DTB from Linux 6.17+ that sets the mode to
rgmii-id, these changes are necessary to avoid using an unsupported/
reserved configuration. See the commit message of patch 2/2 for some
additional detail.

4b10bcfdef net: ethernet: ti: am65-cpsw: fix up PHY mode for fixed RGMII TX delay
The am65-cpsw driver currently sets the SEL_RGMII_IDMODE flag in a MAC's
mode register to enable or disable the TX delay. While this was supported
for earlier generations of the CPSW controller, the datasheets of all
modern TI SoCs using the am65-cpsw MAC state that the TX delay is fixed,
and the SEL_RGMII_IDMODE bit is documented as reserved in most of them.
Furthermore, while it was found that this bit does in fact disable the TX
delay, [1] states that this setting is truly unsupported by TI and not
just undocumented.

Following the clarification of the rgmii* phy-mode values in the Linux
DT bindings in [2], the Linux am65-cpsw driver was changed in [3] to
account for the fixed TX delay by fixing up the mode passed to the PHY
driver; a similar fixup already existed in the TI icssg-prueth driver.
[4] followed up on this by explicitly clearing the SEL_RGMII_IDMODE flag
to handle the case where it is set by the bootloader or other firmware
before Linux.

With the above changes, Device Trees that set the recommended "rgmii-id"
mode are now appearing in Linux 6.17+. Avoid setting the unsupported
SEL_RGMII_IDMODE flag for such Device Trees, and instead fix up the PHY
interface mode, thus aligning the U-Boot driver with the Linux kernel.

5ded13d1e2 mtd: spinand: try a regular dirmap if creating a dirmap for continuous reading fails
Continuous reading may result in multiple flash pages reading in one
operation. Typically only one flash page has read/written (a little bit
more than 2-4 Kb), but continuous reading requires the spi controller
to read up to 512 Kb in one operation without toggling CS in beetween.

Roughly speaking spi controllers can be divided on 2 categories:
 * spi controllers without dirmap acceleration support
 * spi controllers with dirmap acceleration support

Firt of them will have issues with continuous reading if restriction on
the transfer length is implemented in the adjust_op_size() handler.
Second group often supports acceleration of single page only reading.
Thus enabling of continuous reading can break flash reading.

This patch tries to create dirmap for continuous reading first and
fallback to regular reading if spi controller refuses to create it.

This makes the U-Boot SPI NAND driver almost the same as in Linux
6.17-rc1. The only major differences are:
 * support of ECC engines. The Linux driver supports different ECC
   engines while U-Boot uses on-die ECC only.
 * per operation maximum SPI bus frequency

1e103284a5 mtd: spinand: Add a ->configure_chip() hook
There is already a manufacturer hook, which is manufacturer specific but
not chip specific. We no longer have access to the actual NAND identity
at this stage so let's add a per-chip configuration hook to align the
chip configuration (if any) with the core's setting.

This is a port of linux commit
da55809ebb45 ("mtd: spinand: Add a ->configure_chip() hook")

f61362c24f mtd: spinand: propagate spinand_wait() errors from spinand_write_page()
Since commit 3d1f08b032dc ("mtd: spinand: Use the external ECC engine
logic") the spinand_write_page() function ignores the errors returned
by spinand_wait(). Change the code to propagate those up to the stack
as it was done before the offending change.

This is a port of linux commit

ccc6b42adc mtd: spinand: Enhance the logic when picking a variant
Currently the best variant picked in the first one in the list provided
in the manufacturer driver. This worked well while all operations where
performed at the same speed, but with the introduction of DTR transfers
this no longer works correctly.

Let's continue iterating over all the alternatives, even if we find a
match, keeping a reference over the theoretically fastest
operation. Only at the end we can tell which variant is the best.

This logic happening only once at boot.

The patch is based on linux commit
666c299be696 (mtd: spinand: Enhance the logic when picking a variant)
created by Miquel Raynal <miquel.raynal@bootlin.com>

The code was a bit restricted in the functionality since not all
required functionality is supported in the u-boot.

49b855662f mtd: spinand: Add read retry support
When the host ECC fails to correct the data error of NAND device,
there's a special read for data recovery method which can be setup
by the host for the next read. There are several retry levels that
can be attempted until the lost data is recovered or definitely
assumed lost.
