Subject: [PATCH v3 2/2] earlycon: Increase options size
Now that the clock frequency is also part of the options, 16 bytes is
too little.
Without this patch dmesg does not show the whole options, Eg:
earlycon: uart0 at MMIO32 0x00000000fedc9000 (options '115200n8,480000')
instead of: '115200n8,48000000'
