Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE

2022-10-31T15:01:31+00:00

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.

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

2022-03-15T09:43:11+00:00

"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.

doc: Rename k210 partitions anchor

2021-02-26T14:30:55+00:00

This anchor is only for the k210 partition layout, so rename it
appropriately. This keeps it from conflicting with the (to be added)
anchor for U-Boot partitions in general.

riscv: Add support for SPI on Kendryte K210

2021-01-18T03:06:26+00:00

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.
