2.7.4
From: 周琰杰 (Zhou Yanjie) <hidden>
Date: 2019-12-09 13:01:14
Support the Ingenic X1000 SoC using the code under arch/mips/jz4740.
This is left unselectable in Kconfig until a X1000 based board is
added in a later commit.

Notes:
v1->v2:
Rebase on top of mips-next, use ingenic-timer driver
for system timer and clocksource.
v2->v3:
Drop the 'apb' node.
v3->v4:
Adjust the node order to make it consistent with
other Ingenic boards.
v4->v5:
No change.
v5->v6:
No change.
v6->v7:
Change my Signed-off-by from "Zhou Yanjie [off-list ref]"
to "周琰杰 (Zhou Yanjie) [off-list ref]" because
the old mailbox is in an unstable state.

Add a device tree for the Ingenic X1000 based YSH & ATIL CU Neo board.
Note that this is unselectable via Kconfig until the X1000 SoC is made
selectable in a later commit.

1.Adjust "model" in "cu1000.dts" to match the description in "devices.yaml".
2.Adjust "bool" in "Kconfig" to avoid duplicate names with subsequent boards.
v4->v5:
1.Rename "cu1000" to "cu1000-neo" to prevent conflicts with subsequent boards
such as "cu1000-geo", and so on.
2.Remove "CONFIG_HZ=100" and "mem=32M@0x0" from defconfg.
3.Modify incorrect comments in DT.
v5->v6:
1.Use "stdout-path = "serial2:115200n8"" instead "stdout-path = &uart2" in DT.
2.Remove "console=ttyS2,115200n8" and "CONFIG_CMDLINE_OVERRIDE=y" from defconfg.
