X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e7d165146a7de5ceb4f68e188b2679f003744f54;p=firefly-linux-kernel-4.4.55.git

sh: kfr2r09 board support - SCIF console

This patch adds basic kfr2r09 board support. Only
the SCIF1 console is supported with this patch, but
this patch and a proper sh7724 configuration is all
that is needed. Combine with an initramfs to have a
small RAM based kernel and distribution booted as
zImage from RAM via JTAG.
