This region of memory is to be reserved as LMB_NOMAP memory in the LMB memory map. The current location of this buffer overlaps with the memory region reserved for the U-Boot image, which is at the top of the usable memory. This worked earlier as the LMB memory map was not global but caller specific, but fails now because of the overlap. Move the TCG event log buffer to the start of the ram memory region instead. Move the location of the early trace buffer and the load buffer for U-Boot(spl boot) accordingly.
