Hello David,

the SPL image size now just fits:
Image Type:   Rockchip RK32 (SD/MMC) boot image
Data Size:    30720 bytes

SPL is successful. But MMC is failing in main U-Boot:

```
U-Boot SPL 2019.04-rc1-00239-gb89074f650 (Feb 17 2019 - 12:41:39 +0100)
Returning to boot ROM...


U-Boot 2019.04-rc1-00239-gb89074f650 (Feb 17 2019 - 12:41:39 +0100)

Model: Tinker-RK3288
DRAM:  2 GiB
MMC:   dwmmc at ff0c0000: 1
Loading Environment from MMC...
```

No further output here.

With some debug output enabled:

```
U-Boot SPL 2019.04-rc1-00239-gb89074f650-dirty (Feb 17 2019 - 13:05:10
+0100)
Returning to boot ROM...
mmc_bind: alias ret=0, devnum=1
env_init: Environment MMC init done (ret=-2)


U-Boot 2019.04-rc1-00239-gb89074f650-dirty (Feb 17 2019 - 13:05:10 +0100)

Model: Tinker-RK3288
DRAM:  2 GiB
mmc_bind: alias ret=0, devnum=1
MMC:   dwmmc at ff0c0000: 1
Loading Environment from MMC...
```

Any suggestion how to proceed?
