It has broken the possibility to create several phram instances when phram is compiled as module. The possibility to add instances via /sys writes to /sys/module/phram/parameters/phram was also broken with mentioned patch. Proposed patch takes the idea of original block2mtd patch to its full extent. Assumption "This function is always called before 'init_phram()'" was also incorrect, so removed the comment. This patch effectively reverts also b11ec57fc6e6d4882ef01a0c09a1dde58f50492e (mtd: phram: fix section mismatch for phram_setup).

* mtd: m25p80: remove M25PXX_USE_FAST_READ KconfigBrian Norris2013-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the compile-time option for FAST_READ, since we have run-time support for detecting it. This refactors the logic for enabling fast-read, such that for DT-enabled devices, we honor the "m25p,fast-read" property but for non-DT devices, we default to using FAST_READ whenever the flash device supports it. Normal READ and FAST_READ differ only in the following: * FAST_READ supports SPI higher clock frequencies [1] * number of dummy cycles; FAST_READ requires 8 dummy cycles (whereas READ requires 0) to allow the flash sufficient setup time, even when running at higher clock speeds Thus, for flash chips which support FAST_READ, there is otherwise no limiting reason why we cannot use the FAST_READ opcode instead of READ. It simply allows the SPI controller to run at higher clock rates. So theoretically, nobody should be needing the compile-time option anyway. [1] I have a Spansion S25FL128S datasheet which says: "The maximum operating clock frequency for the READ command is 50 MHz." And: "The maximum operating clock frequency for FAST READ command is 133 MHz." Signed-off-by: Brian Norris <computersforpeace@gmail.com>

* mtd: m25p80: fix allocation sizeBrian Norris2013-11-07
| | | | | | | | | | | | | | | | | | | | | | | This patch fixes two memory errors: 1. During a probe failure (in mtd_device_parse_register?) the command buffer would not be freed. 2. The command buffer's size is determined based on the 'fast_read' boolean, but the assignment of fast_read is made after this allocation. Thus, the buffer may be allocated "too small". To fix the first, just switch to the devres version of kzalloc. To fix the second, increase MAX_CMD_SIZE unconditionally. It's not worth saving a byte to fiddle around with the conditions here. This problem was reported by Yuhang Wang a while back.

| | | | | | | | | | | | | | | | | | | | | | | | According to the datasheet for Micron n25q256a (N25Q256A13ESF40F) 4-byte addressing mode should be entered as follows: <quote> To enter or exit the 4-byte address mode, the WRITE ENABLE command must be executed to set the write enable latch bit to 1. (Note: The WRITE ENABLE command must NOT be executed on the N25Q256A83ESF40x and N25Q256A83E1240x devices.) S# must be driven LOW. The effect of the command is immediate; after the command has been executed, the write enable latch bit is cleared to 0. </quote> Micron's portable way to perform this for all types of Micron flash is to first issue a write enable, then switch the addressing mode followed by a write disable to avoid leaving the flash in a write- able state.

* mtd: chips: Add support for PMC SPI Flash chips in m25p80.cMichel Stempin2013-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for PMC (now Chingis, part of ISSI) Pm25LV512 (512 Kib), Pm25LV010 (1 Mib) and Pm25LQ032 (32 Mib) SPI Flash chips. This patch addresses two generations of PMC SPI Flash chips: - Pm25LV512 and Pm25LV010: these have 4KiB sectors and 32KiB blocks. The 4KiB sector erase uses a non-standard opcode (0xd7). They do not support JEDEC RDID (0x9f), and so they can only be detected by matching their name string with pre-configured platform data. Because of the cascaded acquisitions, the datasheet is no longer available on the current manufacturer's website, although it is still commonly used in some recent wireless routers (<https://forum.openwrt.org/viewtopic.php?pid=186360#p186360>). The only public datasheet available seems to be on GeoCities: <http://www.geocities.jp/scottle556/pdf/Pm25LV512-010.pdf> - Pm25LQ032: a newer generation flash, with 4KiB sectors and 64KiB blocks. It uses the standard erase and JEDEC read-ID opcodes. Manufacturer's datasheet is here: <http://www.chingistek.com/img/Product_Files/Pm25LQ032C%20datasheet%20v1.6.1.pdf> This patch is resent in order to take into account both Brian Norris remarks and this upstream patch: commit e534ee4f9ca29fdb38eea4b0c53f2154fbd8c1ee Author: Krzysztof Mazur <krzysiek@podlesie.net> Date: Fri Feb 22 15:51:05 2013 +0100 mtd: m25p80: introduce SST_WRITE flag for SST byte programming Not all SST devices implement the SST byte programming command.

* mtd: m25p80: make CONFIG_M25PXX_USE_FAST_READ safe to enableSascha Hauer2013-08-30
| | | | | | | | | | | | | | | | | | | | | | | This patch adds a flag to struct flash_info indicating that fast_read is not supported. This now gives the following logic when determing whether to enable fastread: If the flash chip does not support fast_read, then disable it. Otherwise: 1) enable fast_read if device node contains m25p,fast-read 2) enable fast_read if forced in Kconfig This makes enabling CONFIG_M25PXX_USE_FAST_READ a safe option since we no longer enable the fast_read option unconditionally. For now fast_read is disabled for the everspin mr25h256 and the catalyst devices. Others may need the flag aswell.
