global: Move remaining CONFIG_SYS_SDRAM_* to CFG_SYS_SDRAM_*

2022-12-05T21:06:07Z

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini Reviewed-by: Simon Glass

Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE

2022-10-31T15:01:31Z

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE and this makes it imposible to use CONFIG_VAL(). Rename it to resolve this problem. Signed-off-by: Simon Glass

k210: use the board vendor name rather than the marketing name

2022-03-15T09:43:11Z

"kendryte" is the marketing name for the K210 RISC-V SoC produced by Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210" vendor,SoC compatibility string format in the device tree files and use the SoC name for file names. With these changes, the device tree files are more in sync with the Linux kernel DTS and drivers, making uboot device tree usable by the kernel.

k210: Don't imply CCF

2021-06-17T01:40:58Z

Now that the k210 clock driver does not depend on CCF, we should no longer imply it (and probably should not have in the first place). We can also reduce the pre-relocation malloc arena back to something sensible. Signed-off-by: Sean Anderson Reviewed-by: Leo Yu-Chi Liang

riscv: k210: Rename airam to aisram

2021-05-14T08:20:49Z

This is more consistent with the naming of other ram banks, and matches what Linux is doing. Reported-by: Damien Le Moal Signed-off-by: Sean Anderson

riscv: Enable AI ram on K210

2021-05-14T08:20:49Z

We just need to initialize all the clocks pre-reloc. The clock driver creates a bunch of devices, so we need to increase the pre-reloc malloc arena. Signed-off-by: Sean Anderson

riscv: Enable watchdog for the k210

riscv: Add support for SPI on Kendryte K210

2021-01-18T03:06:26Z

This enables configs necessary for using SPI. The environment is saved to the very end of SPI flash. This is unlikely to be overwritten unless the entire flash is reprogrammed. This also supplies a default bootcommand. It loads an image and device tree from the first partition of the MMC. This is a minimal/least effort bootcmd, so suggestions (especially in the form of patches) are welcome. I didn't set up distro boot because I think it is unlikely that any general-purpose linux distros will ever be ported to this board.
