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