Add core support for a bloblist to convey data from SPL
At present there is no standard way in U-Boot to pass information from SPL to U-Boot proper. But sometimes SPL wants to convey information to U-Boot that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM then it might want to pass the size of SDRAM, or the location of each bank, to U-Boot proper. Add a new 'bloblist' feature which provides this. A bloblist is set up in the first phase of U-Boot that runs (i.e. TPL or SPL). The location of this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else. Information placed in this region is preserved (with a checksum) through TPL and SPL and ends up in U-Boot. At this point it is copied into SDRAM so it can be used after relocation.
