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."

However, the extended JEDEC ID, which is stored in the remaining bytes, also matters, as it is used for identification of some FLASH types.

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. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Reviewed-by: Tudor Ambarus <tudor.ambarus@microchip.com>
2018-12-10mtd: spi-nor: Add a post BFPT parsing fixup hookBoris Brezillon
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.

2018-12-10mtd: spi-nor: Add the SNOR_F_4B_OPCODES flagBoris Brezillon
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.

The "params->size" is defined as "u64". And "info->sector_size" and "info->n_sectors" are defined as unsigned int and u16. Thus, u64 data might have strange data(loss data) if the result overflows an unsigned int. This patch casts "info->sector_size" to an u64.

2018-11-20mtd: spi-nor: fix selection of uniform erase type in flexible confTudor.Ambarus@microchip.com
There are uniform, non-uniform and flexible erase flash configurations. The non-uniform erase types, are the erase types that can _not_ erase the entire flash by their own. As the code was, in case flashes had flexible erase capabilities (support both uniform and non-uniform erase types in the same flash configuration) and supported multiple uniform erase type sizes, the code did not sort the uniform erase types, and could select a wrong erase type size. Sort the uniform erase mask in case of flexible erase flash configurations, in order to select the best uniform erase type size. Uniform, non-uniform, and flexible configurations with just a valid uniform erase type, are not affected by this change. Uniform erase tested on mx25l3273fm2i-08g and sst26vf064B-104i/sn. Non uniform erase tested on sst26vf064B-104i/sn.
