- probe_spi_rdid with opcode 0x9f, usually 3 bytes ID
- probe_spi_res with opcode 0xab, usually 1 byte ID
We are missing the following probe function:
- probe_spi_rems with opcode 0x90, usually 2 bytes ID
RDID provides best specifity (manufacturer, device class and device) and
RES is supported by quite a few old chips. However, RES only returns one
byte and there are multiple flash chips with different sizes on the
market and all of them have the same RES ID.
REMS is from the same age as RES, but it provides a manufacturer and a
device ID. It is therefore on par with the probing for parallel flash
chips and specific enough.
The order in which chips should be detected is as follows:
1. RDID
2. REMS
3. RES

The AT45 series SPI chips are DataFlash EEPROMs which means they have
odd (non-power-of-two) sector sizes, but some of the DataFlash chips can
be configured or ordered with power-of-two sector sizes.
Add probe support for the following Atmel SPI chips:
AT25DF021
AT25DF041A
AT25DF081
AT25DF161
AT25DF321A
AT25DF641
AT25F512B
AT25FS010
AT25FS040
AT26DF041
AT26DF081A
AT26DF161
AT26DF161A
AT26DF321
AT26F004
AT45CS1282
AT45DB011D
AT45DB021D
AT45DB041D
AT45DB081D
AT45DB161D
AT45DB321C
AT45DB321D
AT45DB642D
Add an explanation why the following chips can't be probed:
AT45BR3214B
AT45D011
AT45D021A
AT45D041A
AT45D081A
AT45D161
AT45DB011

AT45DB081A
AT45DB161
AT45DB161B
AT45DB321
AT45DB321B
AT45DB642
Add the ID, but no probing function for this chip:

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.

Powerdown) SPI command to flashrom 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. This is a heavily reworked
version of a patch by Fredrik Tolf, which was
