[PATCH v8 00/21] RISC-V SiFive FU540 support SPL
This series add support for SPL to FU540. U-Boot SPL can boot from L2 LIM (0x0800_0000) and jump to OpenSBI(FW_DYNAMIC firmware) and U-Boot proper from MMC devices.
This series depends on: [1] https://patchwork.ozlabs.org/patch/1281853 [2] https://patchwork.ozlabs.org/patch/1281852
All these together is available for testing here [3] [3] https://github.com/pragnesh26992/u-boot/tree/spl
How to test this patch: 1) Go to OpenSBI-dir : make PLATFORM=generic FW_DYNAMIC=y 2) export OPENSBI=<path/to/opensbi/build/platform/generic/firmware/fw_dynamic.bin> 3) Change to u-boot-dir 4) make sifive_fu540_defconfig 5) make all 6) Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch)

When build U-Boot SPL, meet an issue of undefined reference to 'crc7' for drivers/mmc/mmc_spi.c, so let's compile crc7.c when CONFIG_MMC_SPI selected.

Devicetree files in FU540 platform is synced from Linux, like other platforms does. Apart from these U-Boot in FU540 would also require some U-Boot specific node like clint.
So, create board specific -u-boot.dtsi files. This would help of maintain U-Boot specific changes separately without touching Linux dts(i) files which indeed easy for syncing from Linux between releases.

There are other RAM drivers who also used the same function sdram_copy_to_reg(), so the plan is to move sdram_copy_to_reg() to some common code area and all RAM drivers will use that.
It's better to use the same name sdram_copy_to_reg(), so that in future we can replace all at a time.
Any suggestions are welcome.

Add a support for SPL which will boot from L2 LIM (0x0800_0000) and then SPL will boot U-Boot FIT image (OpenSBI FW_DYNAMIC + u-boot.bin) from MMC boot devices.
SPL related code is leveraged from FSBL (https://github.com/sifive/freedom-u540-c000-bootloader.git)

u-boot.itb need to write on this specific offset so-that the SPL will retrieve it from here and load.
