[L] Change in flashrom[main]: cli_classic: Add rpmc command support
by Matti Finder (Code Review) 28 Oct '24

28 Oct '24

Attention is currently required from: Anastasia Klimchuk, Matti Finder. Hello Anastasia Klimchuk, Peter Marheine, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/84840?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified+1 by build bot (Jenkins) Change subject: cli_classic: Add rpmc command support ...................................................................... cli_classic: Add rpmc command support Added optional support for all the commands specified in JESD260. Added a new optional dependency to openssls libcrypto. Added parsing for the rpmc parameter sfdp table. Added necessary rpmc parameter information to flashchips struct and the flash hardening feature to enable rpmc commands. Tested on the Winbond W25R128JV as a 'SFDP-capable chip'. This patch was done to add rpmc command support to flashrom. This enables users to write root keys to their flash chips while they flash data on the chip. This might become usefull in the future as rpmc support is extended in coreboot. Also adds usefull debug tools to flashrom, which might be usefull in implementing coreboots rpmc support.

[M] Change in flashrom[main]: erasure_layout: Add an option to sacrifice unchanged blocks for speed
by Anastasia Klimchuk (Code Review) 28 Oct '24

28 Oct '24

Attention is currently required from: Aarya, Bill XIE, Peter Marheine. Anastasia Klimchuk has uploaded a new patch set (#10) to the change originally created by Bill XIE. ( https://review.coreboot.org/c/flashrom/+/84721?usp=email ) The following approvals got outdated and were removed: Verified+1 by build bot (Jenkins) Change subject: erasure_layout: Add an option to sacrifice unchanged blocks for speed ...................................................................... erasure_layout: Add an option to sacrifice unchanged blocks for speed The patch adds command line option to handle the following situation: There is a region which is requested to be erased (or written, because the write operation uses erase too). Some of the areas inside this region don't need to be erased, because the bytes already have expected value. Such areas can be skipped. The logic selects eraseblocks that can cover the areas which need to be erased. Suppose there is a region which is partially covered by eraseblocks of size S (partially because remaining areas don't need to be erased). Now suppose we can cover the whole region with eraseblock of larger size, S+1, and erase it all at once. This will run faster: erase opcode will only be sent once instead of many smaller opcodes. However, this will run erase over some areas of the chip memory that didn't need to be erased. Which means, the chip, as a hardware, will wear faster. New command line option sets the maximum % memory that is allowed for redundant erase. Default is 0, S+1 size block only selected if all the area needs to be erased in full. 50 means that if more than a half of the area needs to be erased, a S+1 size block can be selected to cover all area with one block. The tradeoff is the speed of programming operation VS the longevity of the chip. Default is longevity.
