mh I totally forgot about 430973. I still think [0] is the
better solution. IIRC I never uploaded them to Russel's

Only on N900 though:
$ git grep ARM_ERRATA_430973
arch/arm/Kconfig:config ARM_ERRATA_430973
arch/arm/configs/axm55xx_defconfig:CONFIG_ARM_ERRATA_430973=y
arch/arm/configs/omap2plus_defconfig:CONFIG_ARM_ERRATA_430973=y
arch/arm/mach-omap2/board-rx51.c:#ifdef CONFIG_ARM_ERRATA_430973
arch/arm/mach-omap2/pdata-quirks.c: if (IS_ENABLED(CONFIG_ARM_ERRATA_430973)) {
arch/arm/mm/proc-v7.S:#if defined(CONFIG_ARM_ERRATA_430973) && !defined(CONFIG_ARCH_MULTIPLATFORM)
