guruplug/dreamplug porting
Hi,
I was wondering how feasible it is to port barebox on guruplug/dreamplug marvell-based boards.
The most noticeable problem for me is the initialization part in asm (I'm not an asm junkie). Is it possible to reuse the arm code (asm) in the current version of barebox or at least to take it from u-boot sources (according to uboot conf files, uboot uses the arm926ejs as CPU for the guruplug)?
Regards,

so write it in c
a lots of us do so, Sascha or I mostly write the lowlevel init in C now as example the generic lowlevel arm init is done in C now
I did it recently on at91rm9200
and will update the at91sam9 to c also

mostly you can copy it but you will have to put it in the right section

First do more simple, use barebox as a second stage start by u-boot and then write the lowloevel init
in barebox we do not have one lowlevel init per armvx but one generic one so normally the only assembly you could have to write is the board_lowlevel_init which can be written in C anynway

Is it available in git repository?
