	mirror address The allwinner_h3_dramc_map_rows function simulates row addressing behavior when bootloader software attempts to detect the amount of available SDRAM. Currently the line that calculates the 64-bit address of the mirrored row uses a signed 32-bit multiply operation that in theory could result in the upper 32-bit be all 1s. This commit ensures that the row mirror address is calculated using only 64-bit operations.

2020-03-12	hw/arm/allwinner-h3: add SDRAM controller device	Niek Linnenbank
	In the Allwinner H3 SoC the SDRAM controller is responsible for interfacing with the external Synchronous Dynamic Random Access Memory (SDRAM). Types of memory that the SDRAM controller supports are DDR2/DDR3 and capacities of up to 2GiB. This commit adds emulation support of the Allwinner H3 SDRAM controller.
