At least some seem to be marketed by other vendors (too?) but also with
Intel's vendor ID.

Besides a 0xC7 chip erase and a 0xD8 uniform 64kB block erase they
support also erasing the top/bottom 8 8kB blocks with opcode 0x40.
But since this command fails for all addresses outside those ranges,
it is not easily implemented with flashrom's current code base and
hence left out.

      Improve SPI status register pretty printing · 6ee37e28
      Stefan Tauner authored 
      
 - Move all functions related to SPI status registers to a new file
   spi25_statusreg.c. This includes the generic as well as the
   SST-specific functions from spi25.c and the chip-specific functions
   from a25.c and at25.c.
 - introduce helper functions
    * spi_prettyprint_status_register_hex()
    * spi_prettyprint_status_register_bpl()
    * spi_prettyprint_status_register_plain()
   Use the latter on every compatible flash chip that has no better printlock
   function set and get rid of the implicit pretty printing in the SPI probing
   functions.
 - remove
    * spi_prettyprint_status_register_common()
    * spi_prettyprint_status_register_amic_a25lq032() because it can be fully
      substituted with spi_prettyprint_status_register_amic_a25l032().
    * spi_prettyprint_status_register() (old switch, no longer needed)
 - promote and export
    * spi_prettyprint_status_register_amic_a25l05p() as spi_prettyprint_status_register_default_bp1().
    * spi_prettyprint_status_register_amic_a25l40p() as spi_prettyprint_status_register_default_bp2().
    * spi_prettyprint_status_register_st_m25p() as spi_prettyprint_status_register_default_bp3().
 - add #define TEST_BAD_REW and use it for a number of Atmel chips which
   had only TEST_BAD_READ set even though they dont have erasers or a write
   function set.

      Add support for Atmel AT26DF041 · 94b39b47
      Stefan Tauner authored 
      
Wicked chip: No WRSR, no write enable command (but swallows our
default one without a problem), supports an auto-erasing page write
(but even without that page writes are recommended to write the
whole page i.e. operate on a completely erased page), mad
requirements on block refreshments if only partly written.

Found on my Intel D946GZIS and tested with my serprog in situ.
Using the page write by setting JEDEC_BYTE_PROGRAM to 0x11 and using
the spi_chip_write_256 command greatly improves performance and works
flawlessly.

      Use struct flashctx instead of struct flashchip for flash chip access · 63fd9026
      Carl-Daniel Hailfinger authored 
      
Struct flashchip is used only for the flashchips array and for
operations which do not access hardware, e.g. printing a list of
supported flash chips.

struct flashctx (flash context) contains all data available in
struct flashchip, but it also contains runtime information like
mapping addresses. struct flashctx is expected to grow additional
members over time, a prime candidate being programmer info.
struct flashctx contains all of struct flashchip with identical
member layout, but struct flashctx has additional members at the end.

The separation between struct flashchip/flashctx shrinks the memory
requirement of the big flashchips array and allows future extension
of flashctx without having to worry about bloat.

      Refine status register and lock printing of Atmel and AMIC SPI chips · 7a3bd8f2
      Carl-Daniel Hailfinger authored 
      
Add lock printing for AMIC A25L05PT, A25L05PU, A25L10PT, A25L10PU,
A25L20PT, A25L20PU, A25L40PT, A25L40PU, A25L80P, A25L16PT, A25L16PU,
A25L512, A25L010, A25L020, A25L040, A25L080, A25L016, A25L032, A25LQ032
to a25.c.

Add lock printing for Atmel AT26DF081A, AT26DF161, AT26DF161A,
AT26DF321.

Move Atmel AT25*/AT26* lock related functions originally added in r1115
from spi25.c to at25.c.

For SPI chips the lock printing was handled by one common function, but
sharing a common function which only is a big switch() statement doesn't
make sense, especially if we can define lock printing functions per
flash chip anyway.

The printlock function pointer in struct flashchip is used to print
status register and locking information, and serves as replacement for
implicit status register and lock printing during probe. That code will
later be changed to store locking info in a machine- accessible data
structure so flashrom can handle locked regions correctly.

      Add support for Winbond W39V040FB and W39V040FC · 9188240a
      Carl-Daniel Hailfinger authored 
      
Print lock status for all supported Winbond W39* chips:
W39V040A, W39V040B, W39V040C, W39V040FA, W39V040FB, W39V040FC,
W39V080A, W39V080FA, W39V080FA (dual mode).

Fill in correct probe timing for Winbond W39V040C and W39V080FA.

Please note that the W39V040B/W39V040FB pair has identical IDs,
identical read/write/erase, but locking differs. Same applies to
W39V040C/W39V040FC. This causes double detection on chipsets which
support LPC and FWH, making flashing more difficult because the user
has to select the correct chip. This is called the evil twin problem.
A better evil twin handling (patch available) will resolve that problem.

      Unify chip write functions · b30a5ed4
      Carl-Daniel Hailfinger authored 
      The currently used write functions (wrappers) all use helpers which
perform the actual write (inner functions).

The signature of the write wrappers is: int write_chip(struct flashchip
*flash, uint8_t * buf);

The signature of the inner write functions varied a lot. This patch
changes them to: int write_part(struct flashchip *flash, uint8_t *src,
int start, int len);

Did you know that flashrom has only 8 inner write functions for all
flash chips? write_page_write_jedec_common write_sector_jedec_common
write_sector_28sf040 spi_chip_write_256_new spi_chip_write_1_new
spi_aai_write_new write_page_82802ab write_page_m29f400bt

Export all inner write functions.

Change the function signature of wait_82802ab to eliminate single-use
variables.

Remove an error message in write_page_m29f400bt which was printed for
every byte written regardless of success.

Add sharplhf00l04.c to the list of flash chip drivers in the Makefile.
While the functions in there are unused, I suspect we will n...

      Move implicit erase out of chip drivers · f52f784b
      Carl-Daniel Hailfinger authored 
      
Flashrom had an implicit erase-on-write for most flash chip and
programmer drivers, but it was not entirely consistent.

Some drivers had their own hand-rolled partial update functionality
which made handling partial updates from generic code impossible.

Move implicit erase out of chip drivers, and kill some dead erase
functions at the same time. A full chip erase is now performed in the
generic code for all flash chips on write, and after that the whole chip
is written.
