The CONFIG_BOOT_RAW is not user-selectable.  You must add "select
BOOT_RAW" to TOSHIBA_JMR3927 block in arch/mips/Kconfig.

Hmm.  The puts() in arch/mips/jmr3927/common/puts.c looks usable even
on kernel entry.  You can verify if it can really be used on
start_kernel(), then start tracking down the problem.
