1748990ab2 armv8: ls1088aqds: support DSPI mode by hwconfig
BRDCFG4[USBOSC] and BRDCFG5[SPR] register field of Qixis device is used
to control SPI and other IP signal routing.

USBOSC:
0= SPI_CLK used as external USB REFCLK input driven with 24.000 MHz.
SPI devices are unusable in this mode.
1= SPI_CLK used as SPI clock.
SPI devices are usable in this mode. USB block is clocked from
internal sources

SPR[3:2]:
SPI_CS / SDHC_DAT4:7 Routing (schematic net CFG_SPI_ROUTE[3:2]):
00= SDHC/eMMC 8-bit
01= SD Card Rev 2.0/3.0
10= SPI on-board memory
11= TDM Riser / SPI off-board connector.
The default value is 00 if an SDCard/eMMC card is selected as the boot
device.

SPR[1:0]:
SPI_SIN/SOUT/SCK Routing (schematic net CFG_SPI_ROUTE[1:0]):
00= SDHC Sync loop
01= TDM Riser / SPI off-board connector.
10= SPI on-board memory.
11= SPI off-board connector.

By default, the SPI feature is not available, so we need to configure
the above register fields to select the route to the SPI feature.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

44cdb5b6a1 armv8: ls1088ardb: support force SDHC mode by hwconfig
The BRDCFG5[SPISDHC] register field of Qixis device is used
to control SPI and SDHC signal routing.

10 = Force SDHC Mode
  - SPI_CS[0] is routed to CPLD for SDHC_VS use.
  - SPI_CS[1] is unused.
  - SPI_CS[2:3] are routed to the TDMRiser slot.

11 = Force eMMC Mode
  - SPI_CS[0:3] are routed to the eMMC card.

0X = Auto Mode
  - If SDHC_CS_B=0 (SDHC card installed): Use SDHC mode
    described above.
  - Else SDHC_CS_B=1 (no SDHC card installed): Use eMMC
    mode described above.

In default the hardware uses auto mode, but sometimes we need
to use force SDHC mode to support SD card hotplug, or SD sleep
waking up in kernel. This patch is to support force SDHC mode
by hwconfig.
