From 87663c3bef0f6b198945cf3eb83632f461a5d6f8 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Fri, 18 Nov 2022 18:36:27 +0000 Subject: Revert "crossystem: Add board_id property" This reverts commit db1b34f559fdbf5584b57007da43e4dddda43c6a. Reason for revert: seems to break scarlet - b/259702907 Original change's description: > crossystem: Add board_id property > > futility is one of a few places in ChromeOS that uses "mosys platform > version". The goal is to remove this command from mosys. > > This commit adds a new property to crossystem, "board_id", which > reads the board revision from SMBIOS/FDT, and replaces the call in > futility with the appropriate VbGetSystemPropertyInt. > > BUG=b:187790074 > BRANCH=none > TEST="crossystem board_id" on hana and brya > > Change-Id: Id69c8e309c0e509a165aa6da2778573ac7de3455 > Signed-off-by: Jack Rosenthal > Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/vboot_reference/+/4029537 > Reviewed-by: Julius Werner Bug: b:187790074, b:259702907 Change-Id: Ibdc2525d6f395e2ef63354d36ca02b71543e8079 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/vboot_reference/+/4038443 Commit-Queue: Jack Rosenthal Tested-by: Jack Rosenthal Commit-Queue: Brian Norris Reviewed-by: Jack Rosenthal Owners-Override: Jack Rosenthal --- futility/updater_utils.c | 24 +++++++++++++++++++++++- host/arch/arm/lib/crossystem_arch.c | 2 -- host/arch/x86/lib/crossystem_arch.c | 26 -------------------------- utility/crossystem.c | 1 - 4 files changed, 23 insertions(+), 30 deletions(-) diff --git a/futility/updater_utils.c b/futility/updater_utils.c index cc60ee8a..978936fa 100644 --- a/futility/updater_utils.c +++ b/futility/updater_utils.c @@ -23,6 +23,9 @@ #define COMMAND_BUFFER_SIZE 256 +/* System environment values. */ +static const char * const STR_REV = "rev"; + /* * Strips a string (usually from shell execution output) by removing all the * trailing characters in pattern.
