Use direct register access to get the APB clock divider. This reduces code
size and makes the code more efficient.
stm32: Don't use %lu or %lx for formatting, use just %u or %x.2018-05-04T05:52:03+00:00Damien Georgedamien.p.george@gmail.com2018-05-04T05:52:03+00:00urn:sha1:cb3456ddfe330c562b7d7dde64df933ab7d987f1
On this 32-bit arch there's no need to use the long version of the format
specifier. It's only there to appease the compiler which checks the type
of the args passed to printf. Removing the "l" saves a bit of code space.
stm32/irq: Define IRQ priorities directly as encoded hardware values.2018-05-02T04:41:02+00:00Damien Georgedamien.p.george@gmail.com2018-05-02T04:41:02+00:00urn:sha1:a03e6c1e05203bb71ebee50af2a41de404b05078
For a given IRQn (eg UART) there's no need to carry around both a PRI and
SUBPRI value (eg IRQ_PRI_UART, IRQ_SUBPRI_UART). Instead, the IRQ_PRI_UART
value has been changed in this patch to be the encoded hardware value,
using NVIC_EncodePriority. This way the NVIC_SetPriority function can be
used directly, instead of going through HAL_NVIC_SetPriority which must do
extra processing to encode the PRI+SUBPRI.
For a priority grouping of 4 (4 bits for preempt priority, 0 bits for the
sub-priority), which is used in the stm32 port, the IRQ_PRI_xxx constants
remain unchanged in their value.
This patch also "fixes" the use of raise_irq_pri() which should be passed
the encoded value (but as mentioned above the unencoded value is the same
as the encoded value for priority grouping 4, so there was no bug from this
error).
stm32: Use STM32xx macros instead of MCU_SERIES_xx to select MCU type.2018-03-16T23:42:50+00:00Damien Georgedamien.p.george@gmail.com2018-03-16T23:42:50+00:00urn:sha1:e37b8ba5a55c99dbd1e69eb1c99651307b22fd3e
The CMSIS files for the STM32 range provide macros to distinguish between
the different MCU series: STM32F4, STM32F7, STM32H7, STM32L4, etc. Prefer
to use these instead of custom ones.

Newer versions of the HAL use names which are cleaner and more
self-consistent amongst the HAL itself. This patch switches to use those
names in most places so it is easier to update the HAL in the future.
