The console device is registered by platform only in early_init()
callback so any prints before this point will be lost. Introduce an
early console buffer for caching prints before platform early_init().
For crashes before platform early_init(), users can simply dump the
contents of the console_early_buffer[] string using a debugger. The
relative address of the console_early_buffer[] string can be found
using following two commands:
CONSOLE_EARLY_FIFO_ADDR=`${CROSS_COMPILE}objdump -D \
build/platform/generic/firmware/fw_dynamic.elf | \
grep "<console_early_fifo>:" | awk '{print $1}'`
${CROSS_COMPILE}objdump -R build/platform/generic/firmware/fw_dynamic.elf | \
grep $CONSOLE_EARLY_FIFO_ADDR | awk '{print $3}'
