[U-Boot] [PATCH 0/3] sunxi: Yones Toptech BD1078 support
This series goes on top of my previous series that concludes with Ainol AW1 support.
Also, if you're interested by the idea of using sunxi_name_to_gpio_bank, this could be extended for UART as well, where *many* different pin mux setups are possible. We are just lucky that hardware designers usually use the ports that U-Boot selects, but there is no fundamental reason for that.
Each hardware feature exposed through the GPIO pin mux is usually using the same function index (for a given port), so there is no need to define one value per pin: one value per hardware feature per port is sufficient, avoids duplication and makes everything easier to understand.

Sunxi platforms have different possible mmc pin mux setups (except for mmc0), which are different across platforms.
This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig options. This is especially relevant when a second (in addition to mmc0) port is used and CONFIG_MMC_SUNXI_SLOT_EXTRA is enabled.

Hi,
Thanks.
The entire set has been queued up in u-boot-sunxi/next for upstream merging.
Regards,
Hans

Also, if you're interested by the idea of using sunxi_name_to_gpio_bank, this could be extended for UART as well, where *many* different pin mux setups are possible. We are just lucky that hardware designers usually use the ports that U-Boot selects, but there is no fundamental reason for that.
Hi,
p.s.

I'm not really interested in making the #ifdeffery for the uart setup even more complicated, eventually we should get all this info, including all the pinmux stuff from a dtb (shared with the kernel) appended to the u-boot binary, and then this will use standard devicetree pinmux stuff, until we get there I would like to keep this as simple as possible.

Hans

Understood. There was a real need for mmc as the previous setups were just wrong for platforms != (sun4i || sun7i), but in the case of UART, it just remains minimalistic, which is fine.
