Subject: [PATCH] riscv: increase COMMAND_LINE_SIZE value to 2048
Date: Mon, 19 Jan 2026 16:41:10 +0900	[thread overview]
Message-ID: <aW3gFmOlA/Z4kmfJ@adminpc-PowerEdge-R7525> (raw)

From: Austin Kim <austin.kim@lge.com>

SoC people may send many parameters to configure the drivers via kernel 
command line. If COMMAND_LINE_SIZE is not enough, they may go through 
unexpected error.

To avoid the potential pain, we had better increase COMMAND_LINE_SIZE.
