The RZA2MEVB board uses either SCIF2 (SDRAM enabled) or SCIF4 (HyperRAM only) for the serial console. Note that "SCIFA" serial ports on RZ/A2 SoCs use a compressed register layout, hence add support for that to renesas-scif.S.

The platform port was originally contributed by Andrew Victor and Ben Dooks, and later maintained by Greg Ungerer. When I recently submitted cleanups, but Greg noted that the platform no longer boots and nobody is using it any more, we decided to remove it.

Get rid of this, and move the UART remapping to 0xfffe8000 where DTCM reside on some platforms but not on Ux500, so it can be reused moving the UART out of the vmalloc area.

After discussing with the subarch maintainers and Hilscher, we concluded that the netx subarchitecture (Netx 100/500) is no longer maintained or tested, and noone will miss it if we delete it. So delete it. There is a newer Netx 4000 architecture which we may see included at some point, but this will be supported using the standard multiplatform and devicetree mechanisms and is easier to develop from scratch. * tag 'armsoc-drop-netx-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator: ARM: delete netx machine Signed-off-by: Olof Johansson <olof@lixom.net> 2019-06-05T15:36:37+00:00 Thomas Gleixner tglx@linutronix.de 2019-05-29T14:17:56+00:00 urn:sha1:9c92ab61914157664a2fbdf926df0eb937838e45 Based on 1 normalized pattern(s): this software is licensed under the terms of the gnu general public license version 2 as published by the free software foundation and may be copied distributed and modified under those terms this program is distributed in the hope that it will be useful but without any warranty without even the implied warranty of merchantability or fitness for a particular purpose see the gnu general public license for more details extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 285 file(s).
