Subject: ARM: socfpga: Fix socfpga compilation with early_printk() enabled
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ef3f94412a4d7e107392e7c7cfc3e2d0668aa1aa;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ARM: socfpga: Fix socfpga compilation with early_printk() enabled

This fixes early_printk() compilation for
socfpga. (senduart/busyuart/waituart were missing). It does that by
making Picochip code generic.
