2021-06-18stm32mp: stm32prog: handle the next phase after USB re-enumerationPatrick Delaunay
Handle the second USB enumeration only when the flashlayout is received and when phase is PHASE_FLASHLAYOUT.

2021-06-18dfu: dfu_mtd: set max_buf_size to erasesize also for NOR devicesPatrick Delaunay
For NOR devices the logical DFU buffer size is the sector_size, as it is done in dfu_sf.c or in spi/sf_mtd.c (sf_mtd_info.erasesize = flash->sector_size) For NAND the DFU size was already limited to erasesize as has_pages = true. So the mtd dfu backend can use this erasesize for all the MTD devices, NOR and NAND with dfu->max_buf_size = mtd->erasesize This difference was initially copied from MTD command, where data is fully available in RAM without size limitation. This patch avoids to have many sector write in dfu_mtd.c at the end of the DFU transfer and avoids issues with USB timeout or WATCHDOG.

2021-06-17clk: k210: Re-add support for setting rateSean Anderson
This adds support for setting clock rates, which was left out of the initial CCF expunging. There are several tricky bits here, mostly related to the PLLS: * The PLL's bypass is broken. If the PLL is reconfigured, any child clocks will be stopped. * PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent stopping the CPU while we configure PLL0's rate, ACLK is reparented to IN0 while PLL0 is disabled. * PLL1 is the parent of the AISRAM clock. This clock cannot be reparented, so we instead just disallow changing PLL1's rate after relocation (when we are using the AISRAM).

2021-06-17clk: k210: Rewrite to remove CCFSean Anderson
This is effectively a complete rewrite to remove all dependency on CCF. The code is now smaller, and so is the binary. It also takes up less memory at runtime (since we don't have to create 40 udevices). In general, I am much happier with this driver as much of the complexity and late binding has been removed. The k210_*_params structs which were previously used to initialize CCF clocks are now used as the complete configuration. Since we can write our own division logic, we can now do away with several "half" clocks which only existed to provide constant factors of two. The clock IDs have been renumbered to remove unused clocks. This may not be the last time they are renumbered, since we have diverged with Linux. There are also still a few clocks left out which may need to be added back in. In general, I have tried to leave out behavioral changes. However, there is a small bugfix regarding ACLK. According to the technical reference manual, its mux comes *after* its divider (which is present only for PLL0). This would have required yet another intermediate clock to fix with CCF, but with the new driver it is just 2 lines of code :) Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com>
2021-06-17clk: Allow force setting clock defaults before relocationSean Anderson
Since 291da96b8e ("clk: Allow clock defaults to be set during re-reloc state for SPL only") it has been impossible to set clock defaults before relocation. This is annoying on boards without SPL, since there is no way to set clock defaults before U-Boot proper. In particular, the aisram rate must be changed before relocation on the K210, since U-Boot will hang if we try and change the rate while we are using aisram. To get around this, extend the stage parameter to allow force setting defaults, even if they would be otherwise postponed for later. A device tree property was decided against because of the concerns in the original commit thread about the overhead of repeatedly parsing the device tree.

This supports Falcon boot support for Microchip SAMA5D3 Xplained, tested on raw MMC, and on raw NAND. spl_start_uboot() is has the simplest possible implementation. It doesn't test the environment because enabling environment support currently causes the SPL to exceed its maximum size (64 KiB). It doesn't check the serial for incoming characters either because this functionality currently doesn't seem to work from the SPL on this board. Settings for Falcon boot from at FAT partition are also added to avoid compile failures when CONFIG_SPL_OS_BOOT is enabled, but this particular case is currently not functional as adding FAT and partition support cause the SPL to be too big again.
