This patch enables copying of SPL from MMC if `-kernel` parameter is not passed when starting QEMU. SPL is copied to SRAM_A. The approach is reused from Allwinner H3 implementation. Tested with Armbian and custom Yocto image.

* Emulate Boot ROM firmware setup functionality.

*
|
|
* A real Allwinner A10 SoC contains a Boot ROM
|
|
* which is the first code that runs right after
|
|
* the SoC is powered on. The Boot ROM is responsible
|
|
* for loading user code (e.g. a bootloader) from any
|
|
* of the supported external devices and writing the
|
|
* downloaded code to internal SRAM. After loading the SoC
|
|
* begins executing the code written to SRAM.
|
|
*
|
|
* This function emulates the Boot ROM by copying 32 KiB
|
|
* of data at offset 8 KiB from the given block device and writes it to
|
|
* the start of the first internal SRAM memory.
|
|
*
