[PATCH -fixes 0/3] Fixes regarding CONFIG_PHYS_RAM_BASE

From: Alexandre Ghiti
Date: Wed Jul 21 2021 - 04:00:55 EST

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

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.

Revert "riscv: Remove CONFIG_PHYS_RAM_BASE_FIXED"
