Hi, I have got this patch some time ago but I am not still 100% sure about use case. Anyway Soren uses this mode that's why let me send this patch and we can discuss if this can be useful for someone else too.
The use case is to load U-Boot SPL to do init HW and then load images via JTAG because RAM is initialized and then run full u-boot. There is an option to do HW initialization without U-Boot SPL but there are some differences and it is just better to directly use code which will run on the board when everything is tested. Thanks for your inputs, Michal Michal Simek (1): ARM: spl: Introduce JTAG mode arch/arm/include/asm/spl.h | 1 + arch/microblaze/include/asm/spl.h | 1 + common/spl/spl.c | 7 +++++++ 3 files changed, 9 insertions(+) -- 1.8.2.3
