Reduced the sea of enums, and renamed config parameters to match other
implementations, cribbing off of the G0 config, as it is closer to the level
of complexity. Updated initialization code to utilize the new values.
Added flash and LDO configuration from RCC init to be more consistent with
STM32 platform initialization.
PLL configuration on the H7 is pretty involved, and takes a number of
configurations to make it work. In order to make peripheral drivers a bit
easier to implement, working with a soft clock tree in the rcc module which
stores the clock settings for each clock as they are setup such that users
can request the clock value from the RCC module for configuration. Added
getter for the clock which allows the user to pass the base address of the
peripheral, and get the peripheral clock value for convenience.
Clock configuration is still missing values for setting up all of the kernel
clocks for the peripherals, but this is in work, and there is a framework to
do so.
Have tested to 400MHz without issue. Peripherals that are explicitly supported
are working and the clock tree values appear to follow correctly.
Added LDO settings to allow setting the scaling to support high frequencies.
Updates to a base set of includes to map to the h7 include files which are
mainly based on the f7 versions for simple devices (e.g. SPI, USART, GPIO).
Custom files that have been implemented from the datasheet/ref manual include
the memory map, RCC, PWR definitions, and irq.json file for generation of
nvic files for interrupt mapping.
Additional functionality, especially PLL and tweaks for non-F7 compatible
implementations coming in future commits.
Added documentation tree configuration.
