    Subject[PATCH AUTOSEL 5.4 29/80] printk: reduce LOG_BUF_SHIFT range for H8300
    Date
    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.
