From cbce379fafd205c6540a1a076b00bdd35db9b6d7 Mon Sep 17 00:00:00 2001 From: Alistair Francis Date: Wed, 20 Mar 2019 23:05:21 +0000 Subject: [PATCH] boot/opensbi: new package OpenSBI is a much improved alternative to BBL (riscv-pk). Add OpenSBI support to buildroot. Signed-off-by: Alistair Francis [Thomas: - disable target installation, as we install nothing - enable staging installation - enable images installation only when needed - improve the comment about the staging installation] Signed-off-by: Thomas Petazzoni --- DEVELOPERS | 1 + boot/Config.in | 1 + boot/opensbi/Config.in | 25 +++++++++++++++++++++++++ boot/opensbi/opensbi.mk | 41 +++++++++++++++++++++++++++++++++++++++++ 4 files changed, 68 insertions(+) create mode 100644 boot/opensbi/Config.in create mode 100644 boot/opensbi/opensbi.mk diff --git a/DEVELOPERS b/DEVELOPERS index 002ffa09c7..d21e494b14 100644 --- a/DEVELOPERS +++ b/DEVELOPERS @@ -122,6 +122,7 @@ F: package/kvazaar/ F: package/v4l2loopback/ N: Alistair Francis +F: boot/opensbi/ F: package/xen/ N: Alvaro G.
