Luca Ceresoli [Fri, 22 Jun 2018 10:40:16 +0000 (12:40 +0200)]
arm/arm64: zynq/zynqmp: pass the PS init file as a kconfig variable

U-Boot needs to link ps7_init_gpl.c on Zynq or psu_init_gpl.c on
ZynqMP (PS init for short). The current logic to locate this file for
both platforms is:

 1. if a board-specific file exists in
    board/xilinx/zynq[mp]/$(CONFIG_DEFAULT_DEVICE_TREE)/ps?_init_gpl.c
    then use it
 2. otherwise use board/xilinx/zynq/ps?_init_gpl.c

In the latter case the file does not exist in the U-Boot sources and
must be copied in the source tree from the outside before starting the
build. This is typical when it is generated from Xilinx tools while
developing a custom hardware. However making sure that a
board-specific file is _not_ found (and used) requires some trickery
such as removing or overwriting all PS init files (e.g.: the current
meta-xilinx yocto layer).

This generates a few problems:

 * if the source tree is shared among different out-of-tree builds,
   they will pollute (and potentially corrupt) each other
 * the source tree cannot be read-only
 * any buildsystem must add a command to copy the PS init file binary
 * overwriting or deleting files in the source tree is ugly as hell

Simplify usage by allowing to pass the path to the desired PS init
file in kconfig variable XILINX_PS_INIT_FILE. It can be an absolute
path or relative to $(srctree). If the variable is set, the
user-specified file will always be used without being copied
around. If the the variable is left empty, for backward compatibility
fall back to the old behaviour.

Since the issue is the same for Zynq and ZynqMP, add one kconfig
variable in a common place and use it for both.

Also use the new kconfig help text to document all the ways to give
U-Boot the PS init file.

Build-tested with all combinations of:
 - platform: zynq or zynqmp
 - PS init file: from XILINX_PS_INIT_FILE (absolute, relative path,
   non-existing), in-tree board-specific, in board/xilinx/zynq[mp]/
 - building in-tree, in subdir, in other directory

an eMMC module. The module form factor and connection is specific
to Libretech, and has provisions for split vmmc/vqmmc (core and I/O)
voltage supplies, but this board does not wire the vqmmc side. The
H2+/H3/H5 SoCs do not support alternate I/O voltages for eMMC either.
Only 3.3V is supported. A specific module that ties vqmmc to vmmc,
with both at 3.3V, must be used.

Given that a) eMMC is not designed to be hotplugged, b) power is
always provided on the pins, and c) MMC controllers can deal with
missing cards, we can enable this by default. If a module is attached

sunxi: R40: add gigabit ethernet devicetree node

Add a device tree node for the Allwinner R40/V40 GMAC gigabit
ethernet interface.
The R40 SoC does not use the syscon register for GMAC settings.
The gigabit ethernet interface can only be routed to a fixed set of
pins.
Updated to match the Linux kernel's device tree.
