Subject: [PATCH] ARM: rdu2: Initialize DEBUG_LL in entry function
Date: Mon, 3 Jun 2019 12:28:57 -0700 [thread overview]
Message-ID: <20190603192857.28852-1-andrew.smirnov@gmail.com> (raw)
When bootstrapping Barebox via JTAG rdu2_sram_setup() won't be
executed resulting in non functional DEBUG_LL API. Move low-level UART
initialization code to be a part of start_imx6_zii_rdu2() to avoid
that problem.
