Andreas Färber 43ff5acd45 flash: New Spansion FM4 flash driver
The Spansion FM4 family of microcontrollers does not offer a way to
identify the chip model nor the flash size, except for Dual Flash vs.
regular layout. Therefore the family is passed as argument and
wildcard-matched - MB9BFx6x and S6E2CC families are supported.

Iterations showed that ...
1) Just doing the flash command sequence from SRAM loader code for each
half-word took 20 minutes for an 8 KB block.
2) Doing the busy-wait in the loader merely reduced the time to 19 minutes.
3) Significant performance gains were achieved by looping in loader code
rather than in OpenOCD and by maximizing the batch size across sectors,
getting us down to ~2 seconds for 8 KB and ~2.5 minutes for 1.1 MB.
(Tested with SK-FM4-176L-S6E2CC-ETH v11, CMSIS-DAP v23.)

gcc, objcopy -Obinary and bin2char.sh are used for automating the
integration of hand-written assembler snippets.

Jeff Ciesielski 33b048d456 flash: New driver for XMC4xxx microcontroller family
This is a complete flash driver for the Infineon XMC4xxx family of
microcontrollers, based on the TMS570 driver by Andrey Yurovsky.
The driver attempts to discover the particular variant of MCU via a
combination of the SCU register (to determine if this is indeed an
XMC4xxx part) and the FLASH0_ID register (to determine the variant).
If this fails, the driver will not load.
The driver has been added to the README and documentation.

Tests:
* Hardware: XMC4500 (XMC4500_relax), XMC4200 (XMC4200 enterprise)
* SWD + JTAG
* Binary: 144k, 1M

Note:
* Flash protect only partly tested. These parts only allow the flash
  protection registers (UCB) to be written 4 times total, and my devkits
  have run out of uses (more on the way)

Future Work:
* User 1/2(permalock) locking support via custom command
* In-memory flash loader bootstrap (flashing is rather slow...)

Robert Jordens d25355473d flash/nor/jtagspi: add JTAGSPI driver
Many FPGA board speak JTAG and have a SPI flash for their bitstream
attached to them. The SPI flash is programmed by first uploading a
proxy bitstream to the FPGA that connects the JTAG interface to the
SPI interface if the IR contains a certain USER instruction. Then the
SPI flash can be erase, written, read directly through the JTAG DR.

The JTAG and SPI signaling is compatible. Such a proxy bitstream only
needs to connect TDO-MISO, TDI-MOSI, TCK-CLK, and the activate the
chip select when the IR contains the special instruction and the JTAG
state machine is in the DR-SHIFT state.

Cosmin Gorgovan e475896eb1 mini51: support for Nuvoton NuMicro Mini51 series flash memory
Adds a flash driver for Nuvoton MINI51, MINI52 and MINI54 microcontrollers.

At the moment, it only supports the erase and write operations.

These microcontrollers have a 4 / 8 / 16 KB APROM for application code and a
2 KB LDROM for bootloaders. When the MCU has booted off the APROM, the LDROM
isn't mapped in memory but can be programmed, and the other way around.
This means that the ARM core is typically rebooted for programming. After a
successful write or erase operation, it is rebooted again, using the initial
boot source.

This driver only supports programming the APROM.

This driver is a pure JTAG implementation, it doesn't use any SRAM.

I've tested it on a MINI54ZAN microcontroller using an ST-LINK/V2. With the
microcontroller running at the default clock frequency of 22.1184 MHz, speed
seems to be around 1.1 KB/s.

Paul Fertser fccc55225a mdr32fx: support for Milandr's MDR32Fx internal flash memory
This adds example config and flash driver for russian Cortex-M3
microcontroller model.

Run-time tested on MDR32F9Q2I evaluation board; the flash driver
should be compatible with MDR32F2x (Cortex-M0) too but I lack hardware
to test.

There're no status bits at all, the datasheets specifies some delays
for flash operations instead. All being in <100us range, they're hard
to violate with JTAG, I hope. There're also no flash identification
registers so the flash size and type has to be hardcoded into the
config.

The flashing is considerably complicated because the flash is split
into pages, and each page consists of 4 interleaved non-consecutive
"sectors" (on MDR32F9 only, MDR32F2 is single-sectored), so the
fastest way is to latch the page and sector address and then write
only the part that should go into the current page and current sector.

Performance testing results with adapter_khz 1000 and the chip running
on its default HSI 8MHz oscillator:

When working area is specified, a target helper algorithm is used:
wrote 131072 bytes from file testfile.bin in 3.698427s (34.609 KiB/s)

This can theoretically be sped up by ~1.4 times if the helper
algorithm is fed some kind of "loader instructions stream" to allow
sector-by-sector writing.

Pure JTAG implementation (when target memory area is not available)
flashes all the 128k memory in 49.5s.

Flashing "info" memory region is also implemented, but due to the
overlapping memory addresses (resulting in incorrect memory map
calculations for GDB) it can't be used at the same time, so OpenOCD
needs to be started this way: -c "set IMEMORY true" -f
target/mdr32f9q2i.cfg

It also can't be read/verified because it's not memory-mapped anywhere
ever, and OpenOCD NOR framework doesn't really allow to provide a
custom handler that would be used when verifying.

Atmel introduced 6 new Cortex-M4 processors on 2011-10-26
SAM4S16C - 1024KB flash LQFP100/BGA100
SAM4S16B - 1024KB flash LQFP64/QFN64

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.

Erik Botö 4749a40821 Flash driver for em357
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

Spencer Oliver 5319ccd7eb flash: add virtual flash bank driver
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.

Zachary T Welch ae6374e25d split flash.h into into flash/nor/*.h
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.
