The Rockchip RK3288 is based on a quad-core Cortex-A17 CPU and has a good set of peripherals. Various full-featured U-Boot ports are available and this is an attempt to bring those features into mainline. With this series the Firefly RK3288 can boot to a prompt from an SD card.
Simon,
I want to jump 'on your train' and follow you through these Rockchip devices. I have quite some of them and would like to test and complete mainline u-boot code as well as I now and then support other guys in Android and mainline kernel.
Great, nice to hear from you! There's lots to do.
Is there a reachable git repo that I can clone from you, or can you give me a rough starting point (patches and underlying u-boot revision) from where I have to add these zillions of patches you submitted?
Trying to add your patches on to the HEAD revision leads me just deeper and deeper into more patches :)
Sorry I didn't include that in the cover letter. It's u-boot-dm in branch rockchip-working - http://git.denx.de/u-boot-dm.git/
Kind regards Ulrich
Regards, Simon

I followed your README.rockchip and sucessfully created the spl image for download via USB, but trying to load it results in: # ./firefly/tools/mkimage -T rkimage -d ./firefly/spl/u-boot-spl.bin ./firefly/out # cat ./firefly/out | openssl rc4 -K 7c4e0304550509072d2c7b38170d1711 > ./firefly/out.img # rkflashtool l < firefly/out.img rkflashtool: info: rkflashtool v5.2 rkflashtool: info: Detected RK3288... rkflashtool: info: interface claimed rkflashtool: info: MASK ROM MODE rkflashtool: info: load DDR init
rkflashtool is stuck at that point and doesn't return. Serial port is silent.
Second I tried sd-card image # ./firefly/tools/mkimage -T rksd -d firefly/spl/u-boot-spl-dtb.bin out.sd Warning: SPL image is too large (size 0x82b1) and will not boot
Despite of the warning, I copied things to the SD and tried booting but it doesn't light up on serial console.
The only difference I have, compared to your setup, is probably the toolchain. I have tried linaros 4.9._2014.11 and 4.8_2014q2 and ubuntu's 4.9.3, all arm-none-eabi.
The resulting images are of the following size, more or less independent of the compiler I tried:
720965 Jul 9 14:44 u-boot-spl* 29652 Jul 9 14:44 u-boot-spl.bin*
3757 Jul 9 14:44 u-boot-spl.dtb 33453 Jul 9 14:44 u-boot-spl-dtb.bin
1748823 Jul 9 14:44 u-boot* 208876 Jul 9 14:44 u-boot.bin*

Don't you mean this?
./firefly/tools/mkimage -T rkimage -d ./firefly/spl/u-boot-dtb.spl.bin
You need to send U-Boot and its device tree. Perhaps there is a mistake in my instructions but this is what I see here:
http://patchwork.ozlabs.org/patch/487875/
+ +To create a suitable image and write it to the board: + + ./firefly-rk3288/tools/mkimage -T rkimage -d ./firefly-rk3288/spl/u-boot-spl-dtb.bin out + cat out | openssl rc4 -K 7c4e0304550509072d2c7b38170d1711 | rkflashtool l +

3757 Jul 9 14:44 u-boot-spl.dtb 33453 Jul 9 14:44 u-boot-spl-dtb.bin
This needs to be <32KB or it will not boot. It seems to be a Rockchip boot ROM limitation.
With my toolchain it is. I'll check it again later on. I do have a patched toolchain which doesn't add a whole load of unused strings. Maybe that is the difference. Probably I need to cut the size down a bit.
