52  * Emulate Boot ROM firmware setup functionality.
53  *
54  * A real Allwinner A10 SoC contains a Boot ROM
55  * which is the first code that runs right after
56  * the SoC is powered on. The Boot ROM is responsible
57  * for loading user code (e.g. a bootloader) from any
58  * of the supported external devices and writing the
59  * downloaded code to internal SRAM. After loading the SoC
60  * begins executing the code written to SRAM.
61  *
62  * This function emulates the Boot ROM by copying 32 KiB
63  * of data at offset 8 KiB from the given block device and writes it to
64  * the start of the first internal SRAM memory.
65  *
66  * @s: Allwinner A10 state object pointer
67  * @blk: Block backend device object pointer
