* This structure is access by bootloader, Linux kernel and the Linux

* In the bootloader, this structure is accessed by assembly code in start.S,
* so any changes to content or size must be reflected there as well.
* This is placed at a fixed address in DRAM, so that cores can access it
* when they come out of reset. It is used to setup the minimal bootloader
* runtime environment (stack, but no heap, global data ptr) that is needed
* by the non-boot cores to setup the environment for the applications.
* The boot_info_addr is the address of a boot_info_block_t structure
* which contains more core-specific information.
*
* The Linux kernel and the Linux bootoct utility access this structure for
* implementing CPU hotplug functionality and booting of idle cores with SE
* apps respectively.
