This flash driver works on more than just two chips.
(Though it does need work still, e.g. to protect more than 64K.
(On non-'3748-A0 chips where errata allow that.))

For the above targets the exit_point is
optional when used with run_algorithm, so remove it.
This makes updating the algorithm less error prone.

Note that ECC is not currently supported by this driver, although
it is supported by the peripheral.

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.

which breaks e.g. tcl scripts that rely on this for

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.

This patch add support of iMX27 nand flash controller. This is based on
driver for imx31 nand flash controller.
OOB functionality is not fully working. As in mx31 controller, mx2 NFC
has a bug that swap two bytes between SPARE and MAIN buffer.
I used this driver for several months and no problems appear.
Page reads using hwecc4_infix layout segfaulted for check_bad_blocks because
the read assumed a valid data buffer, which check_bad_blocks does not use
(it only passes a 6 byte buffer for the start of OOB).
This version copes with undersized or missing data or oob buffers and uses
random read commands within the page to skip unwanted areas of data/OOB for
speed.
NOTE: Running check_bad_blocks with this layout will be reading infix
OOB locations, not manufacturer bad block markers. This means that if you
check blocks written in infix layout they will appear good, but manufacturer-
marked bad blocks may also appear good.
If you want to scan for manufactuer-marked bad blocks, you need to enable
raw_access before running check_bad_blocks, or use the non-infix layout.

nand_build_bbt() was ignoring the return value from nand_read_page() and
blindly continuing.
It now passes the return value up to the caller if the read fails.

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.
