[MIPS] Alchemy: Renumber interrupts so irq_cpu can work.
one reserved interrupt on au1500 was missed. this broke the au1000 ethernet
driver.

Fix several errors and warnings given by checkpatch.pl:
- space after opening and before closing parentheses;
- opening brace following 'struct' not on the same line;
- leading spaces instead of tabs;
- use of C99 // comments;
- macros with complex values not enclosed in parentheses;
- missing space between the type and asterisk in a variable declaration;
- space between asterisk and function name;
- including <asm/io.h> instead of <linux/io.h> and <asm/irq.h> instead of
<linux/irq.h>;
- use of '__inline__' instead of 'inline';
- space between function name and opening parenthesis;
- line over 80 characters.
In addition to these changes, also do the following:
- remove needless parentheses;
- insert spaces between operator and its operands;
- replace spaces after the macro name with tabs in the #define directives and
after the type in the structure field declarations;
- remove excess tabs after the macro name in the #define directives and in the
'extern' variable declarations;
- remove excess spaces between # and define for the SSI_*_MASK macros to align
with other such macros;
- put '||' operator on the same line with its first operand;
- properly indent multi-line function prototypes;
- make the multi-line comment style consistent with the kernel style elsewhere
by adding empty first line and/or adding space/asterisk on their left side;
- make two-line comments that only have one line of text one-line;
- convert the large multi-line comment in au1xxx_ide.h into several one-liners,
replace spaces with tabs there;
- fix typos/errors, capitalize acronyms, etc. in the comments;
- insert missing and remove excess new lines;
- update MontaVista copyright;
- remove Pete Popov's and Steve Longerbeam's old email addresses...

Defer the unmasking of the count/compare interrupt (IRQ5) till the
clockevent driver initialization:
- only enable the cascaded IRQs 0 thru 4 in arch_init_irq(); kill the
ALLINTS macro -- this change is blessed by AMD as I saw it in their own
patch; :-)
- do not force IRQ5 enabled in plat_time_init() if PM is enabled and there's
no 32 KHz crystal.
Update the copyrights (taking into account my prior changes), also removing
Pete Popov's old email...

Work around the CPU clock miscalculation on Au1000DA/HA/HB due the
sys_cpupll register being write-only, i.e. actually do what the comment
before cal_r4off() function advertised for years but the code failed at.
This is achieved by just giving user a chance to define the clock
explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option,
defaulting to 396 MHz if the option is not given...
The patch is based on the AMD's big unpublished patch, the issue seems to
be an undocumented errata (or feature :-)...

... by getting the PCI resources back into the 32-bit range -- there's no
need therefore for CONFIG_RESOURCES_64BIT either. This makes Alchemy PCI
work again while currently the kernel skips the bus scan.

convert the Alchemy code to irq_cpu.

The problem was introduced in 2.6.18.3 with the casting of some
36bit-defines (PCI memory) in au1000.h to resource_size_t which may be
u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT.
With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed
because the ioremap in arch/mips/au1000/common/pci.c already used the
truncated addresses.
With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan
aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c
fails because the maximum iomem-address is 0xffffffff (32bit) but the
pci-memory-start-address is 0x440000000 (36bit).
To get pci working again, I propose the following patch:
1. remove the resource_size_t-casting from au1000.h again
2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and
necessary here. The 36bit-handling will be done in __fixup_bigphys_addr).
With this patch pci works again like in 2.6.18.2, the gcc-compile warnings
in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

USB OpenHCI host controller on Au1550 only decodes memory addresses from
0x14020000 to 0x1407FFFF according to the databook, which gives 0x60000

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
