A board.h file can now specify the:
1) BOARD_SOPT2_PLLFLLSEL to select the output of the SIM_SOPT2 MUX
from:
MCGFLLCLK
MCGPLLCLK
USB1PFD
IRC48MHZ
2) If it defines BOARD_SIM_CLKDIV3_FREQ then it must define
BOARD_SIM_CLKDIV3_PLLFLLFRAC and BOARD_SIM_CLKDIV3_PLLFLLDIV
which wil be used to cpnfigure SIM_CLKDIV3 [PLLFLLFRAC, PLLFLLDIV]
The warning has been added because: SIM_SOPT2_PLLFLLSEL
is a clock selection that may feed many clock subsystem:
USB, TPM, SDHCSRC, LPUARTSRC. Therefore, there needs to
be a global board level setting to select the source for
SIM_SOPT2_PLLFLLSEL and then derive all the sub selections
and proper fractions/divisors for each modules clock.
The motvations is to version the IP blocks of the Kinetis
K series family of parts.
This added versioning and configuration features for the
Kinetis PMC IP block.
It is envisioned that in the long term as a chip is added.
The author of the new chip definitions will either find
the exact configuration in an existing chip define and
add the new chip to it Or add the PMC fature configuration
#defines to the chip ifdef list in
arch/arm/include/kinetis/kinetis_pmc.h In either case the
author should mark it as "Verified to Document Number:"
taken from the reference manual.
The version KINETIS_PMC_VERSION_UKN has been applied to
most all the SoCs in the kinetis arch prior to this commit.
The exceptions are the CONFIG_ARCH_CHIP_MK60FN1M0VLQ12,
CONFIG_ARCH_CHIP_MK20DXxxxVLH7 All K64 and K66 have ben
Verified PMC configurations.
