2013-01-14flash: EFM32 flash implementationRoman D
Limited (no page unprotect, no block writes) implementation of EFM32 flash support. Verified with EFM32 development kit and STLink V2 adapter using SWD.

2012-09-26Added SPIFI flash driver, algorithms, and docsGeorge Harris
Added a flash driver designed to allow program/erase of memory-mapped SPI flash chips for LPC43xx/LPC18xx family micros. This driver includes three algorithms - erase, write, and SPIFI peripheral initialization (to allow memory-mapped access after a reset). The driver has been added to the flash driver table (drivers.c), and the OpenOCD documentation has been updated to include the flash driver configuration command.

2012-04-26topic: Added support for the SAM4S variantsOlivier Schonken
Atmel introduced 6 new Cortex-M4 processors on 2011-10-26 SAM4S16C - 1024KB flash LQFP100/BGA100 SAM4S16B - 1024KB flash LQFP64/QFN64 SAM4S16A - 1024KB flash LQFP48/QFN48 SAM4S8C - 512KB flash LQFP100/BGA100 SAM4S8B - 512KB flash LQFP64/QFN64 SAM4S8A - 512KB flash LQFP48/QFN48 The SAM4S processors still suffer from the "6 waitstates needed to program device" errata. Other relevant changes are: 1. Address of flash memory starts at 0x400000. 2. EWP (Erase page and write page) only works for the first two 8KB "sectors" 3. Because of the EWP not working for all the sectors, normal page writes have to be used. The default_flash_blank_check is used to check if lockregions should be erased. 4. The EA (Erase All) command takes 7.3s to complete. (Previous timeout was 500 ms) 5. There are 128 lockable regions of 8KB each. Implemented default blank checking, and page erase for load_image scenarios. This is to compensate for the EWP flash commands only working on the first 2 8KB sectors.

2012-03-11flash: retire unused eCos flash driverØyvind Harboe
even the AT91EB40a's flash is covered by CFI and nobody ever submitted any other drivers based on eCos code. It's just possible that this idea was missing documentation and "marketing", but it's in git if somebody wants to resurrect it.

2011-01-14Flash driver for em357Erik Botö
Hi, I took the stm32x NOR flash driver and adapted it for the Ember EM357 chip. This chip is very similar to em351 and stm32w so the driver should be easily extended to support those as well if anyone can get their hands on some of those for testing. changelog: Added NOR flash driver em357 Best regards, Erik Botö

2010-05-26flash: add virtual flash bank driverSpencer Oliver
This adds a virtual flash bank driver that allows virtual banks to be defined that refer to an existing flash bank. For example the real address for bank0 on the pic32 is 0x1fc00000 but the user program will either be in kseg0 (0xbfc00000) or kseg1 (0x9fc00000). This also means that gdb will be aware of all the read only flash addresses. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>

2009-12-04split flash.h into into flash/nor/*.hZachary T Welch
Move the bulk of the flash.h file into flash/nor/core.h, leaving an empty husk that will be removed in the next patch. The NOR driver structure is an implementation detail, so move it into its own private header file <flash/nor/driver.h> along with helper declaration for finding them by name.
