From: John Ogness <john.ogness@linutronix.de>
[ Upstream commit 550c10d28d21bd82a8bb48debbb27e6ed53262f6 ]
The .bss section for the h8300 is relatively small. A value of CONFIG_LOG_BUF_SHIFT that is larger than 19 will create a static printk ringbuffer that is too large. Limit the range appropriately for the H8300.
