1ffabeaf3d Rename BSP_DIR to PLATFORM
Updates references to CONFIG_BSP_DIR to CONFIG_PLATFORM as part of the
BSP -> platform clean up.

Note that despite the renaming, the usage of the config option remains
unchanged.

a1bd59de35 Eliminate obsolete coding convention comments
Gets rid of single-line comments required by a previous set of
coding conventions. These comments provide no value to readers
and just clutter things up.

bbe84f8ae5 Use ccflags-y and asflags-y instead of EXTRA_CFLAGS
According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build.  This patch converts to them to the newer ccflags-y which also
fixes the problem.

140d314336 Eliminate references to k_memset() and k_memcpy()
Since the kernel now provides a minimal string library, there is
no longer any reason not to use the standard memset() and memcpy()
APIs.

627155afeb PCI scan by BAR number
Added BAR (Base Address Registers) as a parameter for PCI scan.
Some devices (as UART in Quark) use two set of BARs for different
purposes. A driver may require only one of them.

BARs are numbered from 0 to PCI_MAX_BARS.
PCI_BAR_ANY means ignore the BAR number. Constants are defined
in drivers/pci.h

If device class is not specified as a scanning parameter, and
set to 0, ignore it.

d3a4177d92 pci: Provide a simpler yet powerful PCI enumeration API
This fixes many issues around PCI enumeration from old API:
- a static internal table was fed with scanning results, thus eating
  memory, and worse: due to the limit of its size, scanning for new
  classes was impossible unless growing statically the size of this
  table --> more memory eaten! Not to mention PCI enumeration is done
  once at boot time for driver initialization and that's all, so this
  table is hanging around for nothing afterwards.
- one needs first to scan a class, then maybe he will be able to find
  his device via pci_dev_find. Where all could be done at once.
- pci_dev_find was not trustworthy due again to the internal table. Now
  if the device is not found, one will know it really went through all
  the possbilities.
- still let the possibility for hard-coded BARs value on driver side
  (thus no PCI scan required). However this is greatly advised not to do
  so as BARs might change over a firmware/BIOS update.

Comparison:

old pci_dev_scan: could only filter out via class mask.
new pci_dev_scan: can filter out via a class, a vendor and device ID
(it could easily do the same for Function and BAR index as these are
usually fixed and informed through datasheet)

old pci_dev_scan: was limited in its findings by the size of the
internal result table.
new pci_dev_scan: can proceed through all the buses and devices every
time (there are optimizations to avoid useless work of course)

old results did not tell about the function or BAR index.
new one tells, and the structure has not bloated.

old internal code: was storing a big table of results
new internal code: is only storing a small lookup structure and an
array of Bus:Dev pairs for each PCI class for optimizations purpose.
(though, if needed, we could disable this through some #ifdef)

Usage:

- Have a local struct dev_info
- Fill it with what you want to look for, currently: only class and
  vendor_id/device_id. Function and BAR index could be added if needed.
- Call pci_bus_scan_init(): this will reset the internal lookup
  structure.
- Call pci_dev_scan(<a pointer to your dev_info>): at first call, the
  internal lookup structure will pick up the informations from dev_info
  and will try to find out what has been requested. It will return 1 on
  success, or 0. On 1, your dev_info structure will be updated with the
  found informations. If more devices can be found against the same
  lookup informations, just call again pci_dev_scan(<a pointer to your
  dev_info>) as long as it returns 1. When 0 is hit, it will mean you
  found all.

dbada63eee Fix coding style issues.
Some checkpatch issues were solved by scripts leaving other problems
such as alignment and indentation issues.  In order to comply with the
defined coding style the following fixes were made:

- Fixed the function declaration moving the parameters' comments above
  the function in accordance to the doxygen format.
- Fixed functions' opening and closing brackets. These brackets should
  not be indented.
- Fixed the 'if', 'for' and 'while' statements adding the brackets
  around the sentence.
- Fixed comments' alignment.
- Fixed indentation.

The work was done manually and submitted as one commit. I didn't
separate these changes in different commits because they were fixed all
at once. Basically, all errors were fixed in every file at once.
