[BNX2]: Optimize firmware loading.
This is a follow up to the patches from Denys Vlasenkos <vda.linux@googlemail.com> to further optimize firmware loading. 1. In bnx2_init_cpus(), we allocate memory for decompression once and use it repeatedly instead of doing this for every firmware image. 2. We eliminate the BSS and SBSS firmware sections in bnx2_fw*.h since these are always zeros. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
