Add the VT8237A id to src/southbridge/via/vt8237r/bootblock.c I missed this one since it was working anyway, since "The LPC BIOS ROM is always accessed when ISA addresses FFF80000-FFFFFFFF and 000F0000-000FFFFF are decoded" (VT8237R datasheet) And the rom I use for testing is smaller than this 512KB default range.
