Subject: [PATCH 0/2] ppc/pnv: ADU model for POWER9/10
Date: Wed, 17 Apr 2024 21:02:11 +1000 [thread overview]
Message-ID: <20240417110215.808926-1-npiggin@gmail.com> (raw)
These patches adds the framework for a proper ADU model rather than
putting registers into the xscom default ops, and implements ADU's
indirect LPC access functionality which IBM's proprietary firmware
uses to provide consoles on UARTs.
Patch 1 should be quite a simple hooking up the xscom address space.
Patch 2 implements one of the memory access functions of the ADU that
drives access to LPC address space from XSCOM register operations which
is non-trivial but there are similar examples already in tree.
Thanks,
Nick
