      spi25.c: Refactor spi_write_status_register helpers · 96c2dfc1
      Stefan Tauner authored 
      
In r1115 "Write protection handling for Atmel AT25*" the old
spi_write_status_register function was duplicated to send WREN and
EWSR commands respectively controlled by a new common wrapper function
spi_write_status_register without a reason. Both functions' resulting
code is equal apart from the opcode used. The code itself does also
differ in the macros used, but their value (apart from the opcode) is
equal. This patch adds a new parameter for the opcode to the helper
function which allows removal of the other one. This relies on the fact
that EWSR and WREN have the same INSIZE and OUTSIZE though. If that is
really seen as an issue, the sizes could be made parameters too.

This patch also changes the wrapper so that it no longer sets the
feature bits of the struct flash(ctx) argument. This may result in
changed output, because it no longer implicitly disables the debug
message in following executions. Since almost all chips had their
feature bits fixed in the previous commit, this is a minor problem.

Also, spi_write_status_enable has been dead code since r658 or so.
Remove it.

      Tag all EWSR chips correctly · 3603a28a
      Steven Zakulec authored 
      
All SPI chips without a WRSR feature bit set were evaluated except the
Sanyo LF25FW203A for which no datasheet is available.

The following list includes all SPI-capable chips that still have no
WRSR feature bit set:
 - AT26DF041
 - AT45CS1282
 - AT45DB011D
 - AT45DB021D
 - AT45DB041D
 - AT45DB081D
 - AT45DB161D
 - AT45DB321C
 - AT45DB321D
 - AT45DB642D

All of them have no write function set and can be therefore ignored
for now.

Apart from those the generic chips are also not tagged. The opaque
flash interface should not be affected. The SFDP dummy chip is
changed to explicitly set EWSR if it can't deduce it dynamically.
The vendor detecting generic chips can't write anyway.

      Fix SFDP probing · 75adf32a
      Stefan Tauner authored 
      
Sfdp_add_uniform_eraser checks for existing erasers. Due to a bug it
looked for eraser slots that have no erase functions set instead of
those that have one set.

Postpone adding an erase function for the special 4k block erase
opcode until we know the flash chip size and add an additional check
to sfdp_add_uniform_eraser.

Fix the output of the parameter table contents.

This patch fixes the index used to retrieve the eraser types, which
was off one double word.

Refine some messages and add a few further debugging prints.

      SPI command black-/ignorelisting for the flash chip emulator in the dummy programmer · 1b83be5c
      Carl-Daniel Hailfinger authored 
      
Usage:
flashrom -p dummy:spi_blacklist=commandlist
flashrom -p dummy:spi_ignorelist=commandlist

If commandlist is 0302, flashrom will refuse (blacklist) or ignore
(ignorelist) command 0x03 (READ) and command 0x02 (WRITE). The
commandlist can be up to 512 bytes (256 commands) long.
Specifying flash chip emulation is a good idea to get useful results.

Very useful for testing corner cases if you don't own a locked down
Intel chipset and want to simulate such a thing.

Example usage:
dd if=/dev/zeros bs=1024k count=4 of=dummy_simulator.rom
dd if=/dev/urandom bs=1024k count=4 of=randomimage.rom
flashrom -p dummy:emulate=SST25VF032B,image=dummy_simulator.rom,\
spi_blacklist=20,spi_ignorelist=52 -w randomimage.rom -V
