Subject: [PATCH 1/4] EFI stub: remove -fdata-sections
Date: Tue, 06 Nov 2018 13:40:09 +0000 [thread overview]
Message-ID: <E1gK1aT-0000oL-Nn@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20181106133935.GB30658@n2100.armlinux.org.uk>
Remove -fdata-sections from the EFI stub build as this causes problems
for the ARM decompressor code.
