[meta-ti] U-boot with TPS659037

This is based of the beagleboard_X15 board.c
The write to the PMIC to hold power on is limited to a 8 bit address and
the new PMIC has a longer address.
int board_late_init(void)
{
init_sata(0);
/*
* DEV_CTRL.DEV_ON = 1 please - else palmas switches off in 8 seconds
* This is the POWERHOLD-in-Low behavior.
*/
palmas_i2c_write_u8(TPS65903X_CHIP_P1, 0xA0, 0x1);
return 0;
}
We have attempted to use i2c_write and it still seems to not write.
Our current workaround is to have a uenvcmd =i2c mw 0x58 0x1A0 0x1 1 in
the uEnv.txt to do the i2cwite.
Any suggestions are appreciated
Thanks
-Josh
