Subject: [PATCH 1/1] RISC-V: load initrd wherever it fits into memory
Date: Tue, 29 Jun 2021 15:40:18 +0200	[thread overview]
Message-ID: <20210629134018.62859-1-xypron.glpk@gmx.de> (raw)

Requiring that initrd is loaded below RAM start + 256 MiB led to failure
to boot SUSE Linux with GRUB on QEMU, cf.
https://lists.gnu.org/archive/html/grub-devel/2021-06/msg00037.html

Remove the constraint.
