bootloader.s: same MEMIF fix as in int.s plus DPLL BYPASS fix Both MEMIF and DPLL settings are now the same between int.s and bootloader.s assembly code paths. Previously bootloader.s was setting DPLL BYPASS /2 mode, which persisted until _INT_Initialize code with the bootloader body omitted, or was changed to /1 in the hardware init function in the bootloader.lib:start.obj module.
