2019-05-14helper/command: change prototype of command_print/command_print_samelineAntonio Borneo
To prepare for handling TCL return values consistently, all calls to command_print/command_print_sameline should switch to CMD as first parameter. Change prototype of command_print() and command_print_sameline() to pass CMD instead of CMD_CTX. Since the first parameter is currently not used, the change can be done though scripts without manual coding. This patch is created using the command: sed -i PATTERN $(find src/ doc/ -type f) with all the following patters: 's/\(command_print(cmd\)->ctx,/\1,/' 's/\(command_print(CMD\)_CTX,/\1,/' 's/\(command_print(struct command_\)context \*context,/\1invocation *cmd,/' 's/\(command_print_sameline(cmd\)->ctx,/\1,/' 's/\(command_print_sameline(CMD\)_CTX,/\1,/' 's/\(command_print_sameline(struct command_\)context \*context,/\1invocation *cmd,/' This change is inspired by http://openocd.zylin.com/1815 from Paul Fertser but is now done through scripting.

2016-10-30flash/nor: Add erased_value to drivers and pass it to targetsAndreas Färber
struct flash_driver has a default_padded_value field that is similar, but it can be changed by the user for the specific purpose of padding. Add a new erased_value field and initialize it for all targets, particularly stm32lx, xmc4xxx and virtual. Use this value in core.c:default_flash_mem_blank_check(), the slow path. Extend the target API to pass erased_value down to target code. Adding an argument ensures that we catch all callers. This allows us to merge xmc4xxx.c:xmc4xxx_blank_check_memory() into armv7m:armv7m_blank_check_memory(). It further allows us to use default_flash_blank_check() in place of xmc4xxx.c:xmc4xxx_flash_blank_check(), adding a potential slow path fallback, as well as stm32lx:stm32lx_erase_check(), adding the potential armv7m fast path with fallback to default_flash_mem_blank_check(). Fix a mips32 code comment while at it (zeroed -> erased). The armv4_5 and mips32 target implementations will now error out if an erase value other than 0xff is used, causing default_flash_blank_check() to fall back to the default_flank_mem_blank_check() slow path.

Topaz reports on http://sourceforge.net/p/openocd/tickets/87/ that protection level constants are mixed up. This leads to device ending up in protection level 1 after mass erase. Additional work is required to actually put the device in RDP Level 1 and then back to Level 0, as Option bootloader launch is a special kind of full target reset. To be able to flash properly after mass_erase a "reset init" is needed (it's anyway recommended to always perform it before any flash operation).

2014-08-19stm32lx: refactor and add support for STM32L0xxAndrey Yurovsky
This adds initial support for the STM32L0 family, specifically the ID code 417 variant. The 'L0 has 128B rather than 256B pages as well as a different number of pages per sector. It also has several key registers and register sets in different locations from the STM32L1xx parts. This change therefore takes the opportunity to reorganize part information into a const table (it was previously determined by a set of control statements) and abstracts away some of the low-level details to make them generic for L1 and L0 parts. We also include the first bank's size (for dual bank parts) in the new device information table (and correct that size for the 0x437 variant which is 256 rather than 192KB). The 'L0 parts will not use the built-in loader/helper for Flash writing. Tested on STM32L053 (dicovery board and Nucleo board) and STM32L152 (discovery board).

This fixes an issue if the device is manually probed after the initial probe fails due to being unable to read flash size register. In this situation the driver assumes the user has overridden the flash size when infact this may not be the case. It also seems on the older stm32f1 devices the flash register is not readable when locked, this does not seem to apply to the newer parts - f0, f3, f4.

2013-02-25stm32: add support for stm32l1x 256k high density single bank devicesJohan Almquist
Added support for new ST devices in the stm32lx portfolio, with device id 0x427. These have 256k flash, but in a single bank compared to device id 0x436 which is a dual bank flash.

2013-02-25stm32: add support for the STM32Lx 384kb dual bank flashJohan Almquist
This update adds support for the STM32Lx 384kb dual bank flash. Previously there was a problem when writing an image that was larger than 192Kb. That lead to openocd printing out two error messages like "Error: access denied / write protected" and "Error: invalid program address". The reason was that the stm32lx driver tried to write half pages which overlapped into the next flash bank. A new configuration file stm32lx_dual_bank.cfg can be used for stm32lx chips with dual bank flash (256kb or 384kb devices). A sanity check was added for probed flash size values to fix the issue seen on some ST samples that answered incorrectly.

2013-02-25stm32: enable flash bank size overrideSpencer Oliver
It has been seen on some stm32 targets that the flash size register that is probed by the driver may contain an invalid size. This change enables the user to override the probed value.

2013-01-21flash: add stm32lx loader Hard Fault workaroundSpencer Oliver
An issue has been seen with the stm32lx flash driver that if a power cycle/reset is applied after a erase, any ram loader will Hard Fault on execution. A similar issue is mentioned in the errata for the device. Two solution's seem to workaround this issue: 1, Handle the exception, this means adding exception vectors to the loader and changing the exception address using nvic vtor register. 2. falling back to using slower direct page writes - approx 50% slower. Using solution 1 would mean restrictions are placed on the loader location. Solution 2 was chosen mainly as it was simpler too implement.

Handle any leading bytes upto the next 128 byte page, enabling us to safely use the faster page write. Rather than use a separate word/byte write to program any trailing bytes we use a combined write function. Use memcpy for byte writes and change loader to using bytes.
