From aa3bc365ee73765af5059678bf55b0f3e4a3e6c4 Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Sat, 16 May 2020 09:20:46 -0700 Subject: [PATCH] powerpc/ps3: Add check for otheros image size 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'.
