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.
