[PATCH 16/16] riscv: Remove unused instruction headers
From: Charlie Jenkins via B4 Relay
Date: Wed Apr 08 2026 - 00:48:37 EST
From: Charlie Jenkins <thecharlesjenkins@xxxxxxxxx>
All usages of hard-coded riscv instruction have been migrated over to
the generated instruction headers so the old macros can be deleted.
Signed-off-by: Charlie Jenkins <thecharlesjenkins@xxxxxxxxx>
