/**
* struct acr_r361_flcn_bl_desc - DMEM bootloader descriptor
* @signature: 16B signature for secure code. 0s if no secure code
* @ctx_dma: DMA context to be used by BL while loading code/data
* @code_dma_base: 256B-aligned Physical FB Address where code is located
* (falcon's $xcbase register)
* @non_sec_code_off: offset from code_dma_base where the non-secure code is
* located. The offset must be multiple of 256 to help perf
* @non_sec_code_size: the size of the nonSecure code part.
* @sec_code_off: offset from code_dma_base where the secure code is
* located. The offset must be multiple of 256 to help perf
* @sec_code_size: offset from code_dma_base where the secure code is
* located. The offset must be multiple of 256 to help perf
* @code_entry_point: code entry point which will be invoked by BL after
* code is loaded.
* @data_dma_base: 256B aligned Physical FB Address where data is located.
* (falcon's $xdbase register)
* @data_size: size of data block. Should be multiple of 256B
*
* Structure used by the bootloader to load the rest of the code. This has
* to be filled by host and copied into DMEM at offset provided in the
* hsflcn_bl_desc.bl_desc_dmem_load_off.
