From: Mans Rullgard <redacted> Some SoCs use a Palmchip BK-310x UART which is mostly 16550 compatible but with a different register layout.
... because UART register layout is where we really need innovation. ;)
While this UART has previously only been supported in MIPS based chips (Alchemy, Ralink), the ARM based SMP87xx series from Sigma Designs also uses it. This patch allows the debug console to work with this type of UART. Signed-off-by: Mans Rullgard <redacted> Signed-off-by: Marc Gonzalez <redacted>
It appears this was previously acked by Arnd also? https://lkml.org/lkml/2015/11/9/116

minor nit: We're trying (not always with great success) to keep various parts of this file sorted alphanumerically. Can you please insert the new entries accordingly? Otherwise looks good to me, Acked-by: Kevin Hilman <khilman@baylibre.com> Kevin
