Add driver for the SH QSPI controller. This SPI controller is often
connected to the boot SPI NOR flash on R-Car Gen2 platforms.
Add the following two lines to board TCL file to bind the driver on
R-Car Gen2 SoC and make SRAM work area available:
flash bank flash0 sh_qspi 0xe6b10000 0 0 0 ${_TARGETNAME}0 cs0
${_TARGETNAME}0 configure -work-area-phys 0xe6300000 -work-area-virt 0xe6300000 -work-area-size 0x10000 -work-area-backup 0
To install mainline U-Boot on the board, use the following procedure:
proc update_uboot {} {
# SPL
flash erase_sector 0 0x0 0x0
flash write_bank 0 /u-boot/spl/u-boot-spl.bin 0x0
# U-Boot
flash erase_sector 0 0x5 0x6
flash write_bank 0 /u-boot/u-boot.img 0x140000
}
