During the migration to the common clock framework, calls to the functions omap2xxx_clkt_vps_late_init() and omap2xxx_clkt_vps_check_bootloader_rates() were not preserved for OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and "curr_prcm_set" to be uninitialised on boot. On reboot, this causes the following error message to be displayed because the appropriate MPU clock frequency (derived from sys_ck_rate) cannot be found.
"Could not set MPU rate to 4294MHz" Fix this by adding back calls to omap2xxx_clkt_vps_late_init() and omap2xxx_clkt_vps_check_bootloader_rates() in the OMAP2420 and OMAP2430 clock initialisation code.
