Change in flashrom[master]: spi: Allow cached ID bytes to be cleared
by Edward O'Callaghan (Code Review) 26 Aug '20

26 Aug '20

Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/41399 ) 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(a)chromium.org> && `commit 7f7c711ee1a41649607f81f1533e5135fc1361fc`.

Tested using an SF600 (FW v7.2.21), IS25LP256D, W25Q256JV, and MX25L25735.

Change in flashrom[master]: flashrom.c: do not delete programmer arguments

Nikolai Artemiev has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/44562 ) Change subject: flashrom.c: do not delete programmer arguments ...................................................................... flashrom.c: do not delete programmer arguments Make extract_param() leave parameters in tact rather than deleting them as they are retrieved. Deleting them is undesierable as makes the function more complex and requires that extract_programmer_param() does not get called for the same parameter multiple times, which can be difficult to gaurentee for some programmer initialization cases.
