Hello build bot (Jenkins), David Hendricks, Angel Pons,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/41399
to look at the new patch set (#3).
Change subject: spi: Allow cached ID bytes to be cleared ......................................................................
spi: Allow cached ID bytes to be cleared
This does two things: 1. Removes the static variables from various ID functions and moves them to a single struct. 2. Adds a function to clear the struct.
The idea of the original caching mechanism introduced years ago was simply to speed up probe_flash() by not issuing the same read ID commands dozens or hundreds of times for a single chip.
That implementation assumed that we would only call probe_flash() once. However, there are cases when we want to call probe_flash() multiple times, for example, if using an external programmer and using different voltages (for probing the chip).
This patch is extremely similar to the original works of: `commit 57b7524b1448189d3630d6c4735e60dbbdf14d51`. Author: David Hendricks dhendrix@chromium.org && `commit 7f7c711ee1a41649607f81f1533e5135fc1361fc`. Author: David Hendricks dhendrix@chromium.org
