While writing a new SPI driver I fixed some things in the SPI code:
All calls to spi_command() had unneccessary #define duplications, and in some
cases the read count define could theoretically become harmful because NULL was
passed for the read buffer. Avoid a crash, should someone change the #defines.

I also noticed that the only caller of spi_page_program() was the it87 driver,
and spi_page_program() could only call back into the it87 driver. Removed the
function for easier-to-follow code and made it8716f_spi_page_program() static.
The ichspi driver's static page functions are already static.

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.

* ICH7 SPI support
* fix some variable names in ichspi.c (Offset -> offset)
* Dump ICH7 SPI bar with -V
* Improve error message in case IOPL goes wrong. (It might not even be an IOPL)

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.

Add support for the JEDEC RES (Read Electronic Signature and Resume from
Powerdown) SPI command to identify older SPI chips which can't handle
JEDEC RDID.

Since RES gives a one-byte identifier which is shared among many
different vendors and even different sizes, we want to match RES as a
last resort if RDID returns 0xff 0xff 0xff.

Signed-off-by: Fredrik Tolf <fredrik@dolda2000.com>

Flash chips which can be detected by JEDEC probe routines all have
vendor IDs with correct parity. Use a parity check as additional hint
whether a vendor ID makes sense. Note: Device IDs have no parity
requirements whatsoever.

This paves the way to have a fully generic generic_spi_command without
knowledge about any SPI controller.

The third step would be calling SPI controller functions via a function
pointer.

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.

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.

The first chip the code was tested and verified with is the Macronix

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.
