[U-Boot] [PATCH] logbuff: Change default console loglevel to 8

[Peter Tyser]

Previously, a default of 3 was assigned to the console loglevel while
standard messages had a level of 4.  This resulted in U-Boot's console
disappearing if a user enabled CONFIG_LOGBUFFER but didn't manually set
the 'loglevel' environment variable to a value greater than 4.

Setting the default console loglevel to 8 causes all messages to be
printed to the console, which is standard U-Boot operation.  Users can
then reduce the console loglevel if they want using the 'loglevel'
environment variable.
