Event Timeline
| sys/arm/allwinner/a10_mmc.c | ||
|---|---|---|
| 200 ↗ | (On Diff #18246) | Can you make it #else /* __aarch64__ */ so it's documented what the else case if for. |
| sys/arm/allwinner/aw_rtc.c | ||
| 67 ↗ | (On Diff #18246) | #else /* __arm__ */ |
| sys/arm/allwinner/aw_usbphy.c | ||
| 44 ↗ | (On Diff #18246) | Why is this needed? |
| 183–184 ↗ | (On Diff #18246) | Use %jd and cast phy to an intmax_t |
| sys/arm/allwinner/clk/aw_gate.c | ||
| 140 ↗ | (On Diff #18246) | Why not just return? There's no tear down in the failure case that a goto would simplify. |
| sys/arm64/conf/GENERIC | ||
| 201–203 | These shouldn't be added to GENERIC | |
| sys/conf/files.arm64 | ||
| 108 | This is already in sys/conf/files. | |
| sys/arm/allwinner/aw_rtc.c | ||
|---|---|---|
| 68 ↗ | (On Diff #18246) | Also maybe update the RTC driver to have the year min/max stuff into softc so we don't rely on allwinner_soc_family would be better. |
| sys/arm/allwinner/a10_mmc.c | ||
|---|---|---|
| 262 ↗ | (On Diff #18246) | Agreed |
| 323 ↗ | (On Diff #18246) | Agreed |
| sys/arm/allwinner/a64/files.a64 | ||
| 1 ↗ | (On Diff #18246) | I left it here because I thought we might want to support sun50i in the 32-bit ALLWINNER kernel some day. It doesn't matter to me if files.a64 stays or goes but I think sys/arm is the right place for these files. |
| sys/arm/allwinner/aw_rtc.c | ||
| 68 ↗ | (On Diff #18246) | I can remove the dependency on allwinner_soc_family easily but I think refactoring the driver is best left for a separate commit. |

I think the following files can just be committed:

a10_gpio.c
a10_mmc.c
a64_padconf.c
a64_r_padconf.c
aw_ccu.c

| 195 ↗ | (On Diff #18253) | Can you use ofw_bus_is_compatible here? |
Comment Actions
I think most of the .c and .h files are ready, other than if_awg*. I'm undecided on how to handle dts files for arm64 so hold off on adding them for now.
| sys/conf/files.arm64 | ||
|---|---|---|
| 14–37 | You should only use soc_allwinner_a64 for SoC specific attachments. For these you should create a new device name. | |

Can you talk more about this? We have a bit of a mess at the moment in arm land that's closely related to the u-boot mess that we have that I've started to clean up.
Comment Actions
Support both USB host controllers on A64. The first host controller shares a PHY with the OTG controller, so we need to configure the PHY appropriately. Now both USB ports work on Pine64.
Comment Actions
Use the A64 watchdog to reset the system; the psci reboot method doesn't seem to work.
