Hi Sean
This patch series adds support for Sipeed Maix boards and the Kendryte K210 CPU. Currently, only the Maix Bit V2.0 is supported, however other models are similar.
Known Bugs/Limitations:
- Accessing the AI ram hangs, limiting available ram to 6M
- Trying to boot an image with bootm fails with ERROR: Failed to allocate 0x7d60 bytes below 0x80000000.
To flash u-boot to a maix bit, run kflash -tp /dev/<your tty here> -B bit_mic u-boot-dtb.bin
Boot output should look like the following:
U-Boot 2020.04-rc2-00087-g2221cc09c1-dirty (Feb 28 2020 - 13:53:09 -0500)
DRAM: 8 MiB In: serial@38000000 Out: serial@38000000 Err: serial@38000000 =>
Changes for v8:
- Removed dependency on the patch "clk: Add functions to register CCF clock structs". Hopefully this will make reviewing easier.
I have applied this patch series to u-boot-riscv/master except [PATCH v8 14/21] riscv: Clean up IPI initialization code. Because it will cause some warnings as below:
arch/riscv/lib/andes_plic.c: In function 'riscv_init_ipi': arch/riscv/lib/andes_plic.c:84:12: warning: initialization makes integer from pointer without a cast [-Wint-conversion] int ret = syscon_get_first_range(RISCV_SYSCON_PLIC); ^~~~~~~~~~~~~~~~~~~~~~ arch/riscv/lib/andes_plic.c:86:13: warning: passing argument 1 of 'IS_ERR' makes pointer from integer without a cast [-Wint-conversion] if (IS_ERR(ret)) ^~~ In file included from arch/riscv/lib/andes_plic.c:20:0: include/linux/err.h:34:20: note: expected 'const void *' but argument is of type 'int' static inline long IS_ERR(const void *ptr) ^~~~~~ arch/riscv/lib/andes_plic.c:87:18: warning: passing argument 1 of 'PTR_ERR' makes pointer from integer without a cast [-Wint-conversion] return PTR_ERR(ret); ^~~ In file included from arch/riscv/lib/andes_plic.c:20:0: include/linux/err.h:29:20: note: expected 'const void *' but argument is of type 'int' static inline long PTR_ERR(const void *ptr) ^~~~~~~ arch/riscv/lib/andes_plic.c:88:16: warning: assignment makes pointer from integer without a cast [-Wint-conversion] gd->arch.plic = ret;
after running CI yesterday, it failed in many cases: https://travis-ci.org/github/rickchen36/u-boot-riscv/builds/678023975
and I trace at least two cases belong to your patch 49.59 https://travis-ci.org/github/rickchen36/u-boot-riscv/jobs/678024035
arning, treated as error: /home/travis/build/rickchen36/u-boot-riscv/doc/board/sipeed/maix.rst:173:Error in "code-block" directive: 1 argument(s) required, 0 supplied. .. code-block:: &sysclk { assigned-clocks = <&sysclk K210_CLK_PLL0>; assigned-clock-rates = <800000000>; }; doc/Makefile:69: recipe for target 'htmldocs' failed make[1]: *** [htmldocs] Error 1
I used to have
.. code-block:: dts
but it warned that "dts" was not a valid language, so I dropped it.

I'm not sure what the issue here is. Which specific files are lacking a MAINTAINERS entry?
You need create a MAINTAINERS file in the board directory.
So I will drop your patchs and run CI again today. And hope you can fix them in next version and pass CI verification.
