[M] Change in flashrom[main]: Fix FEATURE_NO_ERASE chips and add test for them

Attention is currently required from: Anastasia Klimchuk, Miklós Márton. Peter Marheine has posted comments on this change by Anastasia Klimchuk. ( https://review.coreboot.org/c/flashrom/+/84203?usp=email ) Change subject: Fix FEATURE_NO_ERASE chips and add test for them ...................................................................... Patch Set 3: (1 comment) File flashrom.c: https://review.coreboot.org/c/flashrom/+/84203/comment/a73930a0_5943095a?us… : PS3, Line 487: for (int i = 0; opcode[i]; i++) { This will always crash if `spi_get_opcode_from_erasefn` doesn't know the eraser, which should be probably be fixed to gracefully bail out. `FEATURE_NO_ERASE` seems to more correctly indicate that the chip doesn't need to be erased before writing, so I don't think it's correct to check that flag when seeing which erase options are supported: it's still meaningful to want to erase a chip without writing it, and some chips might have more efficient erase commands than rewriting with "erased" values which we'd want to support (and probe for support). Since `spi_get_opcode_from_erasefn` might not know the opcode for a custom erasefn (including `BLOCK_ERASE_EMULATION`) and chips that don't require erase on write might still have usable erase opcodes, I think we should just skip this loop if `opcode == NULL`. Possibly also a comment should be added to `FEATURE_NO_ERASE` to document that it controls erase before write specifically. -- To view, visit https://review.coreboot.org/c/flashrom/+/84203?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: I582fe00da0715e9b5e92fcc9d15d5a90a2615117 Gerrit-Change-Number: 84203 Gerrit-PatchSet: 3 Gerrit-Owner: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Miklós Márton <martonmiklosqdev(a)gmail.com> Gerrit-Reviewer: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Miklós Márton <martonmiklosqdev(a)gmail.com> Gerrit-Attention: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Comment-Date: Fri, 06 Sep 2024 03:22:42 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No
