Carl-Daniel Hailfinger c23b3a5732 Handle JEDEC JEP106W continuation codes in SPI RDID. Some vendors like
Programmable Micro Corp (PMC) need this.
Both the serial and parallel flash JEDEC detection routines would
benefit from a parity/sanity check of the vendor ID. Will do this later.

Add support for the PMC Pm25LV family of SPI flash chips.

Carl-Daniel Hailfinger 468413a337 Make sure we delay writing the next byte long enough in SPI byte
programming.
Minor formatting changes.

Ronald Hoogenboom 21efd9ffe2 Omitting the wait for SPI ready when there is no data to be read, e.g.
readcnt==0 saves 10 seconds with the unconditional 10us delay, reducing
programming time for SST25VF016B to 40-45 secs.

Carl-Daniel Hailfinger 29df7a9662 Print the chip status register for all SPI chips on probe if verbose
output is specified.

for ST M25P family and Macronix MX25L family chips.

Carl-Daniel Hailfinger 12a3f1edec To make it easier to add new SPI chips to flashchips.c, rename functions
with multiple possible opcodes from linear numbering at the end (_1, _2)
to include the opcode at the end (_60, _c7). That way, you only have to
take a short look at the data sheet and choose the right function by
appending the opcode listed in the data sheet.
No functional changes.

Carl-Daniel Hailfinger bd7602314b Remove hardcoded wait from SPI write/erase routines and check the chip
status register instead.
This has been tested by Harald Gutmann <harald.gutmann@gmx.net> with a
MX25L4005 chip.

Carl-Daniel Hailfinger 79aa01a6c3 Add generic SPI flash erase and write support to flashrom. The first
chip the code was tested and verified with is the Macronix MX25L4005,
but other chips should work as well.
Timeouts are still hardcoded to data sheet maxima, but the status
register checking code is already there.
Thanks to Harald Gutmann for the initial code on which this is loosely
based.

Carl-Daniel Hailfinger 16f6171eda (forgot to add spi.c)
Move SPI code out of board_enable.c where it started its life. The SPI
chip finding and SPI chip accessor code is moved as well. This can be
split later if we feel like it.

The non-use of svn cp is intentional because the only history we'd have
to preserve are a few commits which were early prototypes of chip
identification code. For those who intend to look at that history, they
can look at board_enable.c revision 2853.
