/**
 * 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.
