[PATCH v4 00/10] m25p80: Add SFDP support

[PATCH v4 00/10] m25p80: Add SFDP support

[Cédric Le Goater]

Hello, 

This patchset adds support for JEDEC STANDARD JESD216 Serial Flash
Discovery Parameters (SFDP). SFDP describes the features of a serial
flash device using a set of internal parameter tables. Support in
Linux has been added some time ago and the spi-nor driver is using it
more often to detect the flash settings and even flash models.

Thanks,

C.

Changes in v4:

 - fixed definition of mx25l25635e
 - removed extern
 - new patches from Patrick

Changes in v3:

 - refresh after 2 years 

Cédric Le Goater (9):
  m25p80: Add basic support for the SFDP command
  m25p80: Add the n25q256a SFDP table
  m25p80: Add erase size for mx25l25635e
  m25p80: Add the mx25l25635e SFPD table
  m25p80: Add the mx25l25635f SFPD table
  m25p80: Add the mx66l1g45g SFDP table
  m25p80: Add the w25q256 SFPD table
  m25p80: Add the w25q512jv SFPD table
  arm/aspeed: Replace mx25l25635e chip model

Patrick Williams (1):
  m25p80: Add the w25q01jvq SFPD table

[PATCH v4 01/10] m25p80: Add basic support for the SFDP command

[Cédric Le Goater]

JEDEC STANDARD JESD216 for Serial Flash Discovery Parameters (SFDP)
provides a mean to describe the features of a serial flash device
using a set of internal parameter tables.

This is the initial framework for the RDSFDP command giving access to
a private SFDP area under the flash. This area now needs to be
populated with the flash device characteristics, using a new
'sfdp_read' handler under FlashPartInfo.

[PATCH v4 02/10] m25p80: Add the n25q256a SFDP table

[Cédric Le Goater]

The same values were collected on 4 differents OpenPower systems,
palmettos, romulus and tacoma.

The SFDP table size is defined as being 0x100 bytes but it could be
bigger. Only the mandatory table for basic features is available at
byte 0x30.

[PATCH v4 04/10] m25p80: Add the mx25l25635e SFPD table

[Cédric Le Goater]

The SFDP table is 0x80 bytes long. The mandatory table for basic
features is available at byte 0x30 and an extra Macronix specific
table is available at 0x60.

4B opcodes are not supported.

[PATCH v4 05/10] m25p80: Add the mx25l25635f SFPD table

[Cédric Le Goater]

The mx25l25635e and mx25l25635f chips have the same JEDEC id but the
mx25l25635f has more capabilities reported in the SFDP table. Support
for 4B opcodes is of interest because it is exploited by the Linux
kernel.

The SFDP table size is 0x200 bytes long. The mandatory table for basic
features is available at byte 0x30 and an extra Macronix specific
table is available at 0x60.

[PATCH v4 10/10] arm/aspeed: Replace mx25l25635e chip model

[Cédric Le Goater]
