Hi, Antony,
I'm sorry, i can't find any code for cache operation in lowlevel_init routine. I mean there are no code maintenance cache in this patch , such as "cache reset" and "dcache enable".

I so sorry! My bad: your lowlevel_init actually does not contain any cache code. common code from arch/mips/cpu/start.S calls mips_cache_reset just after invoking lowlevel_init.

- Your lowlevel_init routine duplicates cache maintenance functions by Paul Burton
(please see commit 4a5d8898bca3e442b6 'MIPS: unify cache initialization code').
Can you tell me which lines involve the cache maintenance function?
Please see mips_cache_reset and dcache_enable functions in the commit 4a5d8898bca3e442b6 'MIPS: unify cache initialization code'.
- Can we select build for ar71xx from .config? I suppose 'No',
because the patch does not add any Kconfig option.
Yes, this patch refer to the au1x00 machine, we can select which target was build.
- Can we put your arch/mips/mach-ath79/ar933x/serial.c into drivers/serial?
Ok.
- The patch is suffering from very very many unused macros in ar71xx.h.
File "ar71xx.h" copy from mainline kernel, the future patch should use other macros.
The patch has whitespace errors, please see this git-am log:
Applying: mips: add base support for atheros ar71xx based SOCs .git/rebase-apply/patch:1180: new blank line at EOF.

Ok, thanks!

We are transitioning towards "Driver Model" and new code should already support it where possible. Thus rewrite at least serial.c as DM compatible driver in drivers/serial/. If possible you should also support device-tree. The next branch in u-boot-mips tree has a patch which adds the initial infrastructure for it on MIPS.
Put all SoC specific header files in arch/mips/include/asm/arch-ath79/. The next branch in u-boot-mips tree already has a patch to support again the creation of symbolic links arch/mips/include/asm/arch -> arch/mips/include/asm/arch-SOC. Apart from that your directory structure is fine.
Add proper Kconfig symbols for your SoC. Also you need to have at least one board that uses your SoC. That board have to be created in board/ directory along with proper Kconfig and MAINTAINERS files. Additionally you need to add a Kconfig defconfig file for your board in directory configs/. I wonder how you got your code compiled without a possibility to select it with Kconfig.
Try to minimize the code in lowlevel_init.S. It is only intended to bring up memory controllers and DRAM and maybe some clocks before a C environment is available. Other code should be always written in C. If your SoC has some SRAM space, you could use that for the initial stack and global data and drop lowlevel_init.S entirely.
Please create at least three patches in your next patch series: 1) add ar933x SoC 2) add serial driver for ar933x (or one for all ath79 compatible SoC's) 3) add one ar933x based board (e.g. an official evaluation kit)
