[PATCH v7 0/8] Add FU740 chip and HiFive Unmatched board support

[Rick Chen]

Hi Green,


I did not sign the Reviewed-by for this patch "board: sifive: add
HiFive Unmatched board support" from v1 to v6.
But it just has been tagged in [v7,7/8] board: sifive: add HiFive
Unmatched board support by yourself.

[v6,6/7] board: sifive: add HiFive Unmatched board support
https://patchwork.ozlabs.org/project/uboot/patch/20210408134020.238658-7-green.wan@sifive.com/

[v7,7/8] board: sifive: add HiFive Unmatched board support
https://patchwork.ozlabs.org/project/uboot/patch/20210422091202.396956-8-green.wan@sifive.com/

Actually I don't like this patch that you mix every things (arch/,
drivers/, common/, doc/)together in this patch.
But it is OK for now.

BTW, in [PATCH v7 1/8] riscv: cpu: fu740: Add support for cpu fu740
I found that arch/riscv/cpu/fu740/cpu.c and arch/riscv/fu540/cpu.c are
100% the same.

And about spl.c, they are only different in the annotation of Copyright
diff fu540/spl.c fu740/spl.c

About the cache.c, they are just different in one character

Originally, I am considering to tell you to re-use the same code base
instead of just copy and create.
After a few days of consideration, I feel it's OK for now.

About
[PATCH v7 2/8] drivers: clk: add fu740 support and
[PATCH v7 4/8] drivers: pci: add pcie support for fu740,
there are still not get any Reviewed-by till now.
For me, it will be better if someone can tag a Reviewed-by here.

Principally, it will be suggested to split drivers from RISC-V
relevant, do not mix them together as Palmer said.

Thanks,
Rick
