We already had the hooks for ccmram and ram1 and ram2 and ram3 and xsram
for "other" ram sections, but there was no method, out of the box, for
placing a function in "normal" ram. The "easy" method of labelling a
function as ".data.someramfunc" causes warnings because code isn't meant
to have a name like ".data*" so we must explicitly add a new code
section.

Add support for a section(s) ".noinit*" that will be allocated in ram,
but not cleared or initialized. This can be used for passing variables
between a bootloader and an app for instance, or even just between
restarts of your application.
Without any assigned usages of the section, there is zero change in ram
usage. The align does nothing when the prior section was already
aligned.
These defines were simply a word containing the number, instead of the
number itself. This provides no value, and implies that there's a
limited set of values. The list was _already_ incomplete, so
misleading, _and_ just noise to maintain. Burn it all.
(well, burn it just a little bit, provide deprecated aliases on the old
values so that code keeps compiling)
We were never going to be capable of supporting every single part
variant with their own files, so stop trying. We've been supporting the
linker script generator for a long time now, so move on from these old
static files.
Breaking: if you were using one of these, and don't wish to use the
linker script generator, you should simply declare a stub linker script,
and include the generic section definitions file, and provide this in
your own application.
Old:
LDSCRIPT = $(OPENCM3_DIR)/lib/stm32/l1/stm32l15xxb.ld
New (linker script generator):
DEVICE=stm32l151cb
New (manual):
* Add file mymemorymap.ld, with contents similar too:
```
MEMORY
{
rom (rx) : ORIGIN = 0x08000000, LENGTH = 256K
ram (rwx) : ORIGIN = 0x20000000, LENGTH = 48K
}
/* Include the common ld script. */
INCLUDE cortex-m-generic.ld
```
LDSCRIPT=mymemorymap.ld
See ld/README for more information on using the linker script generator
Replaced & with &&
Wait for all three bits to be set - SB, MSL, and BUSY.
Old code worked by chance, use booleans to correctly convey intent.

on how to include libopencm3 to your project.

The order of the UCPD1 and UCPD2 bits as described by the
rcc_periph_clken and rcc_periph_rst enums is swapped with regard to the
datasheet. Swap them.

Tested on a medium density part (0x429) that returns the same ids as
before, tested on a high density part that now _doesnt_, but that's now
correct :)
