This patch series converts mccmon6 to use Driver Model and Device Tree in u-boot proper. As the SPL is size constrained (and most notably the device has a strict boot time requirements) for this board (and uses falcon boot) - its conversion to DM/DTB will be added with separate patch series.
In the SPL/u-boot proper it now uses fitImage instead of legacy uImage and DTB.
First patches are responsible for porting Linux's Common Clock Framework [CCF] to u-boot. They add only support for reading clock frequencies and enabling gate'd clocks.
Some notable changes: - Use fitImage to boot Linux kernel (and also use of SPL's Falcon mode when running from parallel NOR flash) - DTS sync with kernel (tag: v4.20) - Decoupling SPL and u-boot proper for easy SPL DM/DTS conversion - Adding CONFIG_CLK for IMX6Q (reuse clock.c file functions) - Conversion to DM_MMC, DM_SPI, and BLK (u-boot proper) - Removal of DM_USB (as this board is not using it - no connector present) - Port of CCF (tag: 5.0-rc3) for imx6q ('dm tree', 'clk dump') (more information regarding design decisions in the patch commit message).
Footprint changes (u-boot.imx): Before conversion: 345 KiB DM conversion (without CCF): 415 KiB With CCF: 421 KiB
