Subject: [PATCH v10 2/8] RISC-V: Rename relocate() and make it global
Date: Wed, 26 Jan 2022 17:14:46 +0530 [thread overview]
Message-ID: <20220126114452.692512-3-apatel@ventanamicro.com> (raw)
In-Reply-To: <20220126114452.692512-1-apatel@ventanamicro.com>
From: Anup Patel <anup.patel@wdc•com>
The low-level relocate() function enables mmu and relocates
execution to link-time addresses. We rename relocate() function
to relocate_enable_mmu() function which is more informative.
Also, the relocate_enable_mmu() function will be used in the
resume path when a CPU wakes-up from a non-retentive suspend
so we make it global symbol.
