The file extension indicates a "Microkernel DEFinitions" file,
and no longer reflects the obsolete VxMicro/Viper branding.

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.

UART on Quark platfor, according to Quark BSP Programmer's
Reference Manual, is located in the following order on PCI bus:
COM2 BAR0: 16550 registers
BAR1: DMA registers
COM1 BAR0: 16550 registers
BAR1: DMA registers
So, the driver on Quark platform has to specify BAR (Base
Address Registers) number, the pci_bus_scan() function looks for.
As long as UART is a concole device, calling pci_show() during
it's initialization does not make any output.

Now for x86 platforms, UART is configured statically or dynamically into
the driver and not anymore in the board's system.c. Thus limiting the
information to be scattered into 2 files instead of 3. Then in future,
it will also be possible to remove driver specific informations from the
generic UART API structure.

By default it is set to 'n'. This will be useful to enable the PCI layer
code if required. On quark boark, it is selected by default as UART
driver needs it currently.

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.

deletes the sub-directory itself. Both of the relocated files are
used during nanokernel initialization, which makes their inclusion
in the main nanokernel source directory logical.
