According to the CG3100 source code the BCM3380 uses only spi flash
and does not have hsspi but legacy spi like 6368, 6358 and others, but
with a max speed of 25MHz, which is not defined in .
This is a piece of code found in spiflash.c:

#if defined(CONFIG_BCM93380)
spi_flash_busnum = LEG_SPI_BUS_NUM;
spi_flash_clock = 2500;
#endif
#if defined(CONFIG_BCM93383)
spi_flash_busnum = HS_SPI_BUS_NUM;
#endif

IMHO bcm63xx patches #345 and #411 are related with the slow boot
speed you are experiencing. I have no idea if BCM3380 supports other
spi clocks.

That is a first step, but there are additional kernel changes required
to boot on 3380, are you also going to submit these?

[Álvaro Fernández Rojas]

Not yet, also my patches for the kernel are based on yours, so maybe you 
should submit them, since you were the first one to implement the support.

BTW, I boot tested bmips on BCM3380 with the following changes:
https://github.com/openwrt-es/openwrt/commit/3c72e4dc2b2bf21f3b1a7ef412fdb60753febae1
https://github.com/openwrt-es/openwrt/commits/bmips-4.1
But I have to say it's painfully slow, because it takes like 150s to 
fully boot on 1 CPU and 400+ on 2CPU :/.


And about bmips target, Jonas wants to add it as a brcm63xx subtarget in 
the future.


Regards,
Álvaro.
