The initialization procedures need to be called in the
following order:
- basic hardware initialization;
- devices initialization;
- hardware clock initialization, that the kernel needs to
run the kernel server.
This way, the board initialization routines is placed
to the pure_early_init level to make sure it runs first,
all device initialization procedures run at pure_init level,
so they are initialized early enough to be used for debugging
if needed. Hardware clock initialization is placed on
nano_early_init level to make sure hardware clock is initialized
just before the kernel server starts.

With this, the UART console has its own initialization which is not
dependent on UART init routines.
This will allow the app to utilize all UARTs for other purposes,
instead of always reserving one for console. Future patch
will enable this choice.
Note that the console init is effectively demoted to pure_init
from pure_early_init. The UART console depends on UART being
initialized, but there is no deferred init at this point.
So this initializes the console a bit later than UARTs,
simply to make sure the UART is initialized before using it.
Once there is a mechanism for some type of deferred initialization,
the UART console init can be promoted back to pure_early.

This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.
Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.
Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.

This driver is a very simple UART driver that can be used to implement
a protocol in application. It has no protocol logic and just allow
application to receive and send data over UART in platform independent
manner.
API is designed to minimize number of required memory copies.
Application is able to provide new buffer every time it decides to
consume received data. It is also able to just alter offset and
reuse current buffer eg if data was corrupted or otherwise invalid.

The timer based pseudo random number generator returns the
number of system clock ticks. If the random number function is
called subsequently in a time less than a system clock tick, it
leads to getting same number.
To prevent this the counter is introduced. Counter gets changed
each call, so it ensures the caller gets different numbers each time
the random number function gets called.

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.

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.

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.

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.
