- 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

which support all commands, but may not exist.
For controllers which support only a subset of commands, it will fail in
unexpected ways. Even if a command is supported by the controller, it
may be unavailable if the controller is locked down.
The new logic checks if RDID could be issued and its return values made
sense (not 0xff 0xff 0xff). In that case, RES probing is not performed.
Otherwise, we try RES.
There is one drawback: If RDID returned unexpected values, we don't
issue a RES probe. However, in that case we should try to match RDID
anyway.

It is (re)created in the "prepare" make target, but that was libpayload.a

This is a school book example of why trivial indent patches just suck
big time.
This error was introduced by a trivial self-acked indent patch and was
never detected (because of a missing Config-abuild.lb)
So, indenting the code for no reason can make it a lot worse (read:
break it) instead of improving it.
I ask everyone to keep this in mind when going on indent-frenzy again.

does not have a mechanism to signal command failure, the SPI host may be
unable to send a given command over the wire due to security or hardware
limitations. The current code ignores these mechanisms completely and
simply assumes almost every command succeeds. Complain if SPI command
execution fails.
Since locked down Intel chipsets (like the one we had problems with
earlier) only allow a small subset of commands, find the common subset
of commands between the chipset and the ROM in the chip erase case. That
is accomplished by the new spi_chip_erase_60_c7() which can be used for
chips supporting both 0x60 and 0xc7 chip erase commands.
Both parts of the patch address problems seen in the real world. The
increased verbosity for the error case will help us diagnose and address
problems better.
