Hi Tom,

Prior to this change we set the gd pointer early so that we can store data in it. This becomes problematic for DM changes as well as being odd in general. Re-work the code paths so that we don't need to set the gd pointer so early and instead can rely upon the normal setting of it.
In order to do this we do need to move certain calls from s_init into spl_board_init(), mainly preloader_console_init and save_omap_boot_params.
Tested on: Beaglebone Black, AM43xx GP EVM, Beagleboard, Beagleboard xM, OMAP5 uEVM, DRA7xx EVM Signed-off-by: Tom Rini trini@ti.com
This seems like it's going in the right direction to me!
Tested on Beaglebone Black.
