commit 5b282665ab9d1f73a071e9b9263c333249e1d8ba

    SeaBIOS: Add Kconfig option to set verbosity level
    
    Previously SeaBIOS's default was used (1). This patch defaults to
    coreboot's console level instead which is approximately the same
    verbosity as SeaBIOS and thus what a user would probably expect.
