Subject: [PATCH 7/9] powerpc/ps3: Add check for otheros image size
Date: Fri, 27 Mar 2020 20:26:23 +0000 [thread overview]
Message-ID: <e0dc92ba82a993c845f8d2bf3ace7465ef5ea996.1585340156.git.geoff@infradead.org> (raw)
In-Reply-To: <cover.1585340156.git.geoff@infradead.org>
The ps3's otheros flash loader has a size limit of 16 MiB for the
uncompressed image. If that limit will be reached output the
flash image file as 'otheros-too-big.bld'.
