Hi folks,
For fun I've done a minimal U-Boot port for the HiKey board, I thought I'd post it here in case anyone else is interested. This work is based on top of Linus Walleij Juno port.
The code can be found here: -
ssh://git@git.linaro.org:/people/peter.griffin/u-boot
Currently the port supports: - 1) Serial 2) eMMC (although only basic read testing) 3) USB (ASIX usb networking works, no mass storage) 4) GPIO
So you have ATF -> u-boot -> kernel / your_own_rtos
The main "useful" thing I suppose is the ability to quickly tftp kernels etc into DDR over the network. Obviously the ability to toggle the LEDs in u-boot is also something to amuse yourself with.
Pre-built binaries can be found here: -
http://people.linaro.org/~peter.griffin/hikey/hikey-u-boot-release_r1/ NB: These are built with the latest PSCI enabled ATF, so you also need to use the corresponding PSCI enabled kernel to get all 8 cores.
The readme on how to replicate everything from source can be found here: -
http://people.linaro.org/~peter.griffin/hikey/hikey-u-boot-release_r1/u-boot... .
Any patches please send them along to me, one obvious missing feature is sdhci support. That doesn't look very hard to get going, as long as we can get the IP clocked and out of reset (and would be significantly easier if the published datasheet documented the registers...).
Have Fun!
regards,
Peter.
