Alexander Sverdlin 2b75ebeea6 mtd: spi-nor: intel-spi: Avoid crossing 4K address boundary on read/write
It was observed that reads crossing 4K address boundary are failing.

This limitation is mentioned in Intel documents:

Intel(R) 9 Series Chipset Family Platform Controller Hub (PCH) Datasheet:

"5.26.3 Flash Access
Program Register Access:
* Program Register Accesses are not allowed to cross a 4 KB boundary..."

Enhanced Serial Peripheral Interface (eSPI)
Interface Base Specification (for Client and Server Platforms):

"5.1.4 Address
For other memory transactions, the address may start or end at any byte
boundary. However, the address and payload length combination must not
cross the naturally aligned address boundary of the corresponding Maximum
Payload Size. It must not cross a 4 KB address boundary."

Avoid this by splitting an operation crossing the boundary into two
operations.

If identification of an SPI NOR FLASH fails, the JEDEC ID is printed,
which is stored in the first 3 bytes of the ID read from the FLASH.
However, the extended JEDEC ID, which is stored in the remaining bytes,
also matters, as it is used for identification of some FLASH types.

Print all (currently 6) ID bytes read to ease failure analysis and

Linus Torvalds 0051db8218 spi: Updates for v4.21
The main thing this release has been a lot of work on the integration
 with SPI NOR flashes, there's been some specific support for a while for
 controller features designed to make them perform better but it's not
 worked out as well as hoped so the interface has been redesigned in a
 way that will hopefully do better - it's already been adopted by a
 number of additional controllers so things are looking good.  Otherwise
 most of the work has been driver specific:
 
  - Support for better integration with NOR flashes from Boris Brezillon
    and Yogesh Narayan Gaur plus usage of it in several drivers.
  - A big cleanup of the Rockchip driver from Emil Renner Berthing.
  - Lots of performance improvements for bcm2835 from Lukas Wunner.
  - Slave mode support for pxa2xx from Lubomir Rintel.
  - Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,
    and Renesas r8a77470.

Cyrille Pitchen 816873eaee mtd: spi-nor: parse SFDP 4-byte Address Instruction Table
Add support for SFDP (JESD216B) 4-byte Address Instruction Table. This
table is optional but when available, we parse it to get the 4-byte
address op codes supported by the memory.
Using these op codes is stateless as opposed to entering the 4-byte
address mode or setting the Base Address Register (BAR).

Flashes that have the 4BAIT table declared can now support
SPINOR_OP_PP_1_1_4_4B and SPINOR_OP_PP_1_4_4_4B opcodes.

Tested on MX25L25673G.

MX25L25635F and MX25L25635E share the same JEDEC-ID, but the F variant
supports 4-byte opcodes while the E variant doesn't. We need a way to
differentiate those 2 chips and set the SNOR_F_4B_OPCODES flag only for
the F variant.

Luckily, 4-byte opcode support is not the only difference: Fast Read
4-4-4 is only supported by the F variant, and this feature is
advertised in the BFPT table. Use this to decide when to set the
SNOR_F_4B_OPCODES flag.

Boris Brezillon 2aaa5f7e0c mtd: spi-nor: Add a post BFPT parsing fixup hook
Experience has proven that SFDP tables are sometimes wrong, and parsing
of these broken tables can lead to erroneous flash config.

This leaves us 2 options:

1/ set the SPI_NOR_SKIP_SFDP flag and completely ignore SFDP parsing
2/ fix things at runtime

While #1 should always work, it might imply extra work if most of the
SFDP is correct. #2 has the benefit of keeping the generic SFDP parsing
logic almost untouched while allowing SPI NOR manufacturer drivers to
fix the broken bits.

Add a spi_nor_fixups struct where we'll put all our fixup hooks, each
of them being called at a different point in the scan process.

We start a hook called just after the BFPT parsing to allow fixing up
info extracted from the BFPT section. More hooks will be added if other
sections need to be fixed.

Boris Brezillon 548ed6847f mtd: spi-nor: Add the SNOR_F_4B_OPCODES flag
Some flash_info entries have the SPI_NOR_4B_OPCODES flag set to let the
core know that the flash supports 4B opcode. While this solution works
fine for id-based caps detection, it doesn't work that well when relying
on SFDP-based caps detection. Let's add an SNOR_F_4B_OPCODES flag so
that the SFDP parsing code can set it when appropriate.
