-/* This allows USB A-A firmware upload from a compatible host in four parts:
- * The first two are the bare BL1 and the Coreboot boot block, which are just
- * written to their respective loading addresses. These transfers are initiated
- * by the IROM / BL1, so this code has nothing to do with them.
- *
- * The third transfer is a valid CBFS image that contains only the romstage,
- * and must be small enough to fit into alternate_cbfs_size[__BOOT_BLOCK__] in
- * IRAM. It is loaded when this function gets called in the boot block, and
- * the normal CBFS code extracts the romstage from it.
- *
- * The fourth transfer is also a CBFS image, but can be of arbitrary size and
- * should contain all available stages/payloads/etc. It is loaded when this
- * function is called a second time at the end of the romstage, and copied to
- * alternate_cbfs_buffer[!__BOOT_BLOCK__] in DRAM. It will reside there for the
- * rest of the firmware's lifetime and all subsequent stages (which will not
- * have __PRE_RAM__ defined) can just directly reference it there.
