2015-11-30cfi_flash: give default CONFIG_SYS_MAX_FLASH_SECT in flash.hThomas Chou
Give default CONFIG_SYS_MAX_FLASH_SECT in flash.h, so that the header can be included regardless of the present of flash. The value 512 is the most used. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Signed-off-by: Stefan Roese <sr@denx.de>
2015-11-12dm: implement a MTD uclassThomas Chou
Implement a Memory Technology Device (MTD) uclass. It should include most flash drivers in the future. Though no uclass ops are defined yet, the MTD ops could be used. The NAND flash driver is based on MTD. The CFI flash and SPI flash support MTD, too. It should make sense to convert them to MTD uclass. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>

2013-01-10mtd/cfi: add support for SST 4KB sector granularityAngelo Dureghello
Add support for SST 4KB sector granularity. Many recent SST flashes, i.e. SST39VF3201B and similar of this family are declared CFI-conformant from SST. They support CFI query, but implement 2 different sector sizes in the same memory: a 64KB sector (they call it "block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector", erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh of cfi query struct, detects a number of secotrs for the 4KB granularity (flinfo shows it). For all other aspects, they are CFI compliant, so, as Linux do, i think it's a good idea to handle these chips in the CFI driver, with a fixup to allow 4KB granularity, as should be expected, instead of 64KB.

2012-08-13mtd/cfi_flash: fix write problems for Numonyx P33/30 32 MBit flashsHolger Brunck
commit 54652991 Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads to problems for smaller versions of this chip e.g. the 32Mbit version with deviceid 0x16 on mgcoge. So move the code for this work around to an own function and check previously manufacturer id and device id to not break other flashes which don't need this work around.

2010-09-20cfi_flash: Simplify dynamic flash bank number detectionStefan Roese
This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By moving these optional variables and defines into the common code, board specific code is minimized. Currently only the following board use this feature: APC405, IDS8247, TQM834x And IDS8247 doesn't seem to really need this feature, since its not updating the bank number variable at all. So this patch removes the definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port. This new framework will be used by the upcoming lwmon5 update as well.

2009-04-04UBI/cfi-mtd: Fix mtd name for multiple chipsAndreas Huber
On platforms with multiple NOR chips, currently only the first one can be selected using the "ubi part" command. This patch fixes this problem by using different names for the NOR "mtd devices". It also changes the name of the NOR MTD device from "cfi-mtd" to "norX" (X indexing the device numer) to better match the mtdparts defaults.

2009-02-11cfi: make flash_get_info() non staticHeiko Schocher
If on your board is more than one flash, you must know the size of every single flash, for example, for updating the DTS before booting Linux.

2009-02-05flash/cfi_flash: Use virtual sector start address, not physBecky Bruce
include/flash.h was commented to say that the address in flash_info->start was a physical address. However, from u-boot's point of view, and looking at most flash code, it makes more sense for this to be a virtual address. So I corrected the comment to indicate that this was a virtual address. The only flash driver that was actually treating the address as physical was the mtd/cfi_flash driver. However, this code was using it inconsistently as it actually directly dereferenced the "start" element, while it used map_physmem to get a virtual address in other places. I changed this driver so that the code which initializes the info->start field calls map_physmem to get a virtual address, eliminating the need for further map_physmem calls. The code is now consistent. The *only* place a physical address should be used is when defining the flash banks list that is used to initialize the flash_info struct, usually found in the board config file.

Add cfi-mtd driver, which exports CFI flash to MTD layer. This allows CFI flash devices to be used from MTD layer. Building of the new driver is controlled by CONFIG_FLASH_CFI_MTD option.

2006-04-01* Changes/fixes for drivers/cfi_flash.c:Stefan Roese
- Add Intel legacy lock/unlock support to common CFI driver On some Intel flash's (e.g. Intel J3) legacy unlocking is supported, meaning that unlocking of one sector will unlock all sectors of this bank. Using this feature, unlocking of all sectors upon startup (via env var "unlock=yes") will get much faster. - Fixed problem with multiple reads of envronment variable "unlock" as pointed out by Reinhard Arlt & Anders Larsen. - Removed unwanted linefeeds from "protect" command when CFG_FLASH_PROTECTION is enabled. - Changed p3p400 board to use CFG_FLASH_PROTECTION Patch by Stefan Roese, 01 Apr 2006 * Changes/fixes for drivers/cfi_flash.c: - Correctly handle the cases where CFG_HZ != 1000 (several XScale-based boards) - Fix the timeout calculation of buffered writes (off by a factor of 1000) Patch by Anders Larsen, 31 Mar 2006

The original code would only check for error bits if flash_status_check() returns ERR_TIMEOUT. Patch by Marcus Hall, 23 Aug 2005 * Changes/fixes for drivers/cfi_flash.c: - Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c - Prohibit buffer write when buffer_size is 1 on drivers/cfi_flash.c Patch by Sangmoon Kim, 19 Aug 2005 * Fixes for drivers/cfi_flash.c: - Fix wrong timeout value usage in flash_status_check() - Round write_tout up when converting to msec in flash_get_size() - Remove clearing flash status at the end of flash_write_cfibuffer() which sets Intel 28F640J3 flash back to command mode on CSB472 Patch by Tolunay Orkun, 02 July 2005
