Subject: [PATCH v2 0/9] powerpc: Add support for Microwatt soft-core
Date: Fri, 18 Jun 2021 13:42:53 +1000 [thread overview]
Message-ID: <YMwWPcsaWzMlDPqQ@thinks.paulus.ozlabs.org> (raw)
This series of patches adds support for the Microwatt soft-core.
Microwatt is an open-source 64-bit Power ISA processor written in VHDL
which targets medium-sized FPGAs such as the Xilinx Artix-7 or the
Lattice ECP5. Microwatt currently implements the scalar fixed plus
floating-point subset of Power ISA v3.0B plus the radix MMU, but not
logical partitioning (i.e. it does not have hypervisor mode or nested
radix translation).
Changes in v2:
- Dropped the patch that adds support for the PRTBL register, since it
is not architected. Instead, I have added support for a 1-entry
partition table to Microwatt and implemented the PTCR register.
- Updated the device tree.
- Dropped the change to archrandom.h.
- Combined patches 10 and 11 of the previous series into one.
Paul.
