 * U-Boot itself into memory at 0x80800000 for legacy reasons (to not conflict
 * with older SPLs).  We have our BSS be placed 2MiB after this, to allow for
 * the default Linux kernel address of 0x80008000 to work with most sized
 * kernels, in the Falcon Mode case.  We have the SPL malloc pool at the end
 * of the BSS area.  We suggest that the stack be placed at 32MiB after the
 * start of DRAM to allow room for all of the above (handled in Kconfig).
