Subject: [RFC PATCH v3 5/6] lib: sbi: sbi_init: call sbi_hart_init() earlier
Date: Sun, 30 Nov 2025 19:16:42 +0800 [thread overview]
Message-ID: <20251130111643.1291462-6-peter.lin@sifive.com> (raw)
In-Reply-To: <20251130111643.1291462-1-peter.lin@sifive.com>
Move sbi_hart_init() earlier in the initialization
sequence, the function initializes reserved PMP regions
before platform-specific early initialization. This
allows platforms to call reserved_pmp_alloc() in their
early_init hooks.
