Subject: [PATCH v3 7/9] powerpc/ps3: Add check for otheros image size
Date: Sat, 16 May 2020 09:20:46 -0700 [thread overview]
Message-ID: <897c2a59-378e-7c9b-3976-d0a0def90913@infradead.org> (raw)
In-Reply-To: <4e8defeb49d62dd9d435e5ea3ddc5668e56fa496.1589049250.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'.
Signed-off-by: Geoff Levand <geoff@infradead.org>

v2: Change from decimal to hex values. Output an INFO message to screen.
v3: Remove the INFO message.
