These series of patch add support for atheros ath79 based SOCs in u-boot,
at the present moment it's just available for ar933x and qca953x chip.
Changes in v6:
- Remove useless "else"
- Move ar933x as separate patch
- Add get_bootstrap in reset.c
- Use map_physmem instead of KSEG1ADDR
- Add arch_cpu_init for detect SOC type for early
- Define magic value in ddr.c
- Remove wait loop in putc and getc
- Use map_physmem instead of KSEG1ADDR
- Add rrw_delay in ath79_spi_priv for more accurate timing
- Remove ath79_spi_delay
- Calculate delay in ath79_spi_set_speed
- Convert SZ_XXX into hex in ap121.h
- Remove useless CONFIG_SYS_INIT_SP_OFFSET in ap121.h
- Add board_early_init_f for DDR and pin initialization
- Select UART and SPI in ap121_defconfig
- Add support for qca953x
I wanted to try this patchset, so I picked [1], since I didn't feel like fishing
out patches from the list. Especially since this wasn't sent as a series, but as
separate patches, which makes things annoying.
The [1] does not even compile, which is surprising. I would expect that if you
submit patches, you would at least compile-test them. Sigh. I needed this patch:

Marek, you can try my repository at
https://github.com/willswang/u-boot-ath79,
I have fixed the compiling issue about headers.
I'm very sorry about this compiling error, my work tree have a residual
symbol
link between arch/mips/include/asm/arch and
arch/mips/mach-ath79/include/mach.
it was not removed when i executed "make clean" to rebuild, so, my
compiling
didn't discover this problem before this. now i clone this remote branch
into a new
location and find this issue.
Once I managed to fix things, I compiled ap121. I tried booting it on arduino
yun (ar9331), but it hung in start.S in setup_c0_status . If I comment this
out, it hangs in lowlevel_init, right at the beginning. That's where I gave up.
