Helper ./src/helper/membuf.c is only used in at91sam3.c
1) Replace membuf with LOG_*
2) The original code in sam3_GetDetails() invalidates
all the buffered output of sam3_GetInfo(). The new
code skips sam3_GetInfo() if its output should not
be printed.

when a write/unlock/erase failed during write_image, then
an error was not propagated back up so e.g. flash write
image from tcl scripts would not throw an exception.
Also flash filling speed was printed even when the
operation failed. Output is now less confusing.

Hello,
"stm32x mass_erase" return ERROR_OK even if something goes wrong.
Here is a summary of changes :
* in stm32x_mass_erase : return ERROR_FLASH_OPERATION_FAILED when error
detected in FLASH_SR register;
* in COMMAND_HANDLER(stm32x_handle_mass_erase_command) : return the
returned value of stm32x_mass_erase().
I don't know if there is reason to always return ERROR_OK ?

When a flash cmd is called using the flash name the autoprobe
function is not called. autoprobe is called if flash_command_get_bank
falls through to get_flash_bank_by_num.
This makes both get_flash_bank_by_name and get_flash_bank_by_num
behave the same.

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.

Every time command "flash probe #" is executed, memory
structures are re-allocated without preventive free()
of former areas, causing memory leak.
Also, memory allocation does not check return value,
determining segmentation fault in case of out of memory.

Final step to force bus_width size during CFI flash

Final target is to force bus_width size during CFI flash
read.
In this first step I need to replace default flash read
with flash specific implementation.
This patch introduces:
- flash_driver_read() layer;
- default_flash_read(), backward compatible;
- read() callback in struct flash_driver;
- proper initialization in every flash_driver instance.

During cfi_write(), head and tail of destination area
could be not aligned to bus_width.
Since write operation must be at bus_width size, source
buffer size is extended and buffer padded with current
values read from flash.
Force using bus_width to read current value from flash.
Do not use cfi_add_byte() anymore, to allow removing this
function later on.

NOR flash structure requires each access to be bus_width wide.
Fix read of flash ID accordingly to rule above.
Add case (chip_width == 4), allowed by CFI spec and coherent
with current value of CFI_MAX_CHIP_WIDTH but currently not
used by any target.

Since NOR flash devices does not handle "byte enable lanes",
each read/write access involves the whole "chip_width".
When multiple devices are in parallel, usually all chips are
enabled during each access.
All such cases are compatible with flash accesses at
"bus_width" size.
Access at "bus_width" size is mandatory for write access to
avoid transferring of garbage values to flash.
During read access the flash controller should take care,
and discard unneeded bytes. Anyway, it is good practice to
use "bus_width" size also for read.
Every memory access that does not respect "bus_width" size
is marked with a "FIXME" comment.

Review and simplify computation of bufferwsize.
Add comments about variables' meaning.
The same code is present 3 times in the file.
Current patch updates all the 3 instances.
Step 1)
Replace "switch(bank->chip_width) {...}".
Illegal values of bank->chip_width are already dropped.
For legal values, the code is equivalent to:
bufferwsize = buffersize / bank->chip_width;
Step 2)
The above code replacement plus the following line:
bufferwsize /= (bank->bus_width / bank->chip_width);
is merged in a single formula:
bufferwsize = (buffersize / bank->chip_width) /
(bank->bus_width / bank->chip_width);
and simplified as:
bufferwsize = buffersize / bank->bus_width;

Arguments chip_width and bus_width of command "flash bank" are
not fully checked.
While bus_width is later on redundantly checked in several other
parts (e.g. in cfi_command_val()) and generates run-time error,
chip_width is never checked, nor related to actual bus_width
value.
Added check to avoid:
- (chip_width == 0), that would mean no memory chip at all,
avoiding also division by zero e.g. in cfi_get_u8();
- (bus_width == 0), that would mean no bus at all;
- unsupported cases of chip_width or bus_width value not power
of 2;
- unsupported case of chip width wider than bus.

Hi,
This is my first post to the list. First, I would like to thank
everyone for their work on OpenOCD, it is a great tool to work with. I
have been using it to debug code on hardware for the Rockbox project
(www.rockbox.org).
The target that I primarily work with has a Spansion/Fujitsu NOR flash
(MBM29SL800TE). I attached a patch that adds support for this flash. I
hope it can be included in the main repository. If there is something
that needs to be changed with the patch before inclusion please let me
know.

There are a million reasons why cached protection state might
be stale: power cycling of target, reset, code executing on
the target, etc.
The "flash protect_check" command is now gone. This is *always*
executed when running a "flash info".
As a bonus for more a more robust approach, lots of code could
be deleted.

This stops GDB from launching with an empty memory map,
making gdb load w/flashing fail for no obvious reason.
The error message points in the direction of the gdb-attach
event that can be set up to issue a halt or "reset init"
which will put GDB in a well defined stated upon attach
and thus have a robust flash autoprobe.
