From fe9435571612066cc897e8c80921cba01c068c64 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 27 May 2020 02:04:52 -0700 Subject: [PATCH] riscv: sbi: Remove sbi_spec_version U-Boot defaults to use SBI v0.2. Howerver there is a global variable sbi_spec_version that stills refers to v0.1. Since it is not used anywhere, let's remove it.
