Subject: [PATCH 17/28] ia64: remove the hpsim platform
Date: Tue, 13 Aug 2019 09:25:03 +0200
Message-ID: <20190813072514.23299-18-hch@lst.de> (raw)
In-Reply-To: <20190813072514.23299-1-hch@lst.de>

The hpsim platform supports the HP IA64 simulator which was useful as a
bring up platform.  But it is fairly non-standard vs real IA64 system
in that it for example doesn't support ACPI.  It also comes with a
whole bunch of simulator specific drivers.  Remove it to simplify the
IA64 port.

Note that through a weird twist only them hpsim boot loader built the
vmlinux.gz file, so the makefile targets for that are moved to the
main ia64 Makefile now.
