Subject: [PATCH v2 3/4] riscv: dts: sophgo: sg2044: Add "b" ISA extension
Date: Thu, 15 Jan 2026 07:18:59 +0800 [thread overview]
Message-ID: <20260115-adding-b-dtsi-v2-3-254dd61cf947@riscstar.com> (raw)
In-Reply-To: <20260115-adding-b-dtsi-v2-0-254dd61cf947@riscstar.com>
"b" is ratified (Apr/2024) much later than its components zba/zbb/zbs
(Jun/2021). With "b" added into riscv/extensions.yaml, a dependency
checking rule is now enforced, which requires that when zba, zbb, and zbs
are all specified, "b" must be added as well. Failing to do this will
cause dtbs_check schema check warnings.
According to uabi.rst, as a single-letter extension, "b" should be added
after "c" in canonical order.
Update sg2044-cpus.dtsi to conform to this rule.

v2: New patch, a split from the Patch 2 in v1. This patch is for
Sophgo sg2044.
