Subject: [PATCH -fixes 0/3] Fixes regarding CONFIG_PHYS_RAM_BASE
Date: Wed, 21 Jul 2021 09:59:34 +0200	[thread overview]
Message-ID: <20210721075937.696811-1-alex@ghiti.fr> (raw)

The following commits: 

7094e6acaf7a ("riscv: Simplify xip and !xip kernel address conversion macros")
9b79878ced8f ("riscv: Remove CONFIG_PHYS_RAM_BASE_FIXED")

expose CONFIG_PHYS_RAM_BASE for all kernel types whereas this value is
implementation-specific, so that breaks the kernel genericity.

The first patch in this patchset removes the usage of CONFIG_PHYS_RAM_BASE
by introducing a new global variable that holds this value.

The second patch reverts 9b79878ced8f ("riscv: Remove 
CONFIG_PHYS_RAM_BASE_FIXED").

The last patch is an optimization 'symmetrical' to the one introduced in
the first patch: this is not a fix, then it is not necessary to pull
this into -fixes.
