Subject: [PATCH v4 1/4] riscv: Remove CONFIG_PHYS_RAM_BASE_FIXED
Date: Fri, 4 Jun 2021 13:49:47 +0200 [thread overview]
Message-ID: <20210604114950.1446390-2-alex@ghiti.fr> (raw)
In-Reply-To: <20210604114950.1446390-1-alex@ghiti.fr>
Make the physical RAM base address available for all kernels, not only
XIP kernels as it will allow to simplify address conversions macros.

Execute-In-Place allows the kernel to run from non-volatile storage
directly addressable by the CPU, such as NOR flash. This saves RAM
