The CONFIG_SPL_BOARD_INIT lets SPL common code call spl_board_init() during the SPL start up. On this particular system, spl_board_init() is used to reconfigure GIC clock parent to PLL2 500M, which is the configuration expected by the Linux kernel. Enable SPL_BOARD_INIT and fill in the GIC clock configuration code. Set GIC clock to 500 MHz for OD VDD_SOC. Kernel driver does not allow to change it. Should set the clock after PMIC setting done. Default is 400 MHz (system_pll1_800m with div = 2) set by ROM for ND VDD_SOC. Signed-off-by: Marek Vasut <marex@denx.de> Reviewed-by: Fabio Estevam <festevam@denx.de> |
