Julius Werner 8c5e4d93db cbfs: Enforce media->map() result checking, improve error messages ... If you try to boot a VBOOT2_VERIFY_FIRMWARE with less than 4K CBFS cache right now, your system will try and fail to validate the FMAP signature at (u8 *)0xFFFFFFFF and go into recovery mode. This patch avoids the memcmp() to potentially invalid memory, and also adds an error message to cbfs_simple_buffer_map() to make it explicit that we ran out of CBFS cache space. BUG=None TEST=Booted on Veyron_Pinky with reduced CBFS cache, saw the message.
