--- v6: - Use agilex-clock.h from Linux instead of using stratix10-clock.h.

v4: - Get address from DT.

v3: - Fixed clear PLL's lostlock bypass mode to ensure the clock manager provide glitchless clock to downstream logic - Changed CM_REG_CLRBITS(), CM_REG_SETBITS() and CM_REG_CLRSETBITS() macros argument ordering, to match with clrbits_le32, setbits_le32 and clrsetbits_le32. - Rename stratix10-clock.h to socfpga-soc64-clock.h. - Convert struct to defines and move defines to clk-agilex.h

--- v5: - Probe CCU driver with DM method.

v4: - Move spl_early_init() to entry of board_init_f - Add socfpga_get_manager_addr(). - Remove SYSMGR_DMA and SYSMGR_DMA_PERIPH, already set in firewall_setup().

v2: - Change clock driver probing to DM. - Remove unused OSC1TIMER0 reset - Remove debug_uart_init(). UART depends on clock driver setup, no point to call debug_uart_init() after spl_early_init() and clock driver initialization. --- arch/arm/mach-socfpga/Makefile | 3 + arch/arm/mach-socfpga/spl_agilex.c | 98 ++++++++++++++++++++++++++++++ 2 files changed, 101 insertions(+) create mode 100644 arch/arm/mach-socfpga/spl_agilex.c
