[U-Boot] Help/Clue to improve Z-turn board support

[Alexandre GRIVEAUX]

Hello,

I tried to have mainline uboot for Z-turn board (patch sent in December, 
wrong window: [PATCH] ARM: zynq: Adding ps7_init_gpl.c for Z-turn board)
Even with the right ps7_init_gpl.c : the board doesn't boot.

I tried to correct zynq-zturn.dts [0] because I don't find MYIR 
references in drivers from this line: compatible = "myir,zynq-zturn", 
"xlnx,zynq-7000";
And the HEADER is not the same as the other boards: same result.

Picking a board (microzed) with zturn DTS above and using 
microzed_defconfig provide some good result to me (except for ethernet)

According to the build messages between zturn and microzed, the make 
command doesn't create this SPL files:

spl/board/xilinx/zynq/.built-in.o.cmd
spl/board/xilinx/zynq/built-in.o
spl/board/xilinx/zynq/zynq-microzed/ps7_init_gpl.o
spl/board/xilinx/zynq/zynq-microzed/.ps7_init_gpl.o.cmd
spl/u-boot-spl

I don’t have a clue how to resolv that.
Do you have any idea ?

Thanks
