Peter Stuge 5dc95de5e6 flashrom: Trivial indent fix in ichspi.c

Carl-Daniel Hailfinger 5bc95858d5 r3415 removed symbolic constants for device IDs by accident.
flash.h is a database of known IDs, whereas flashchips.c is a database
of chips for which support has been implemented. Keep it that way.

Trivial.

Andreas Thienemann ce17f6bdb0 flashrom: Add AMIC A29002
This patch adds support to the AMIC A29002 chip in its top and bottom
configuration to flashrom. Additionally, the alphabetic order of the
AMIC chips was fixed.

The datasheet is at <http://www.amictechnology.com/pdf/A29002.pdf>.

A29002T PREW functionality was tested and works.

This flash chip has asymmetric sector layout so it is important to use the
mx29f002 driver, which does chip erase before writing, rather than am29f040b,
which uses sector erase.

Carl-Daniel Hailfinger 039b848066 Improve coreboot image detection heuristic in flashrom. It's not
absolutely perfect, but the likelihood of this check to fail is
0.000000000000000000000000013 (1.3*10^-26) which is good enough for me.

Stefan Reinauer d9b7ae8bec First attempt to clean up SPI probing and create a common
construct: the flash bus.

At some point the flash bus will be part of struct flashchip.

Pardon me for pushing this in, but I think it is important to beware of further
decay and it will improve things for other developers in the short run.

Carl-Daniel, I will consider your suggestions in another patch. I want to keep
things from getting too much for now. The patch includes Rudolf's VIA SPI
changes though.

Peter Stuge 606a207d9b flashrom: Slight restructure of SPI probe_ functions
Preparation for a probe optimization patch. This patch does not change any
functionality. spi_probe_rdid was tested to still work on my M57SLI rev 2.

The idea is to have error checks return error immediately when something
fails, rather than having code inside an if block where the condition
tests for success.

This means: Less indentation, more clear what the code is checking.

Jens Kuehnel 42b127fe22 flashrom: Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymore
Jens sent the first patch that added A49LF040A to flash.h and flashchips.c
using _jedec and _49lf040 functions.

An issue was found with probe_w29ee011() for the Winbond W29EE011, which
caused the A49LF040A to no longer respond to any commands.

Ward made a patch to disable probing by default for the W29EE011 following
some discussion. Using -c W29EE011 will make flashrom probe for the chip.

Peter did some more datasheet diving and found that the Pm49FL00x functions
suited this chip quite well because of the block locking registers in
A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3.

Ward confirmed that this works on alix.2c3 too.
