riscv: cleanup architecture macro checks

* We really should get out of the habbit of making up
our own architecture defines.
* __riscv with an additional __riscv_xlen is the
standard that developed... let's just roll with it.

riscv32: Drop any remaining mentions

* I added this early on, but to be honest, any interesting
workstation class hardware would be riscv64.
* Since riscv32 is mostly embedded or low power, just drop.

headers/config: Fix RISCV64 define typoed to 32

Change-Id: I20890218f5edd279ab1080432a4d91f5a7f64dee

HaikuConfig: Change _BEOS_COMPATIBLE_TYPES to only be defined on i386.

Hopefully soon we will have our first 32-bit non-x86 architectures.
No functional change for x86 32- and 64-bit intended.

Change all references to "__INTEL__" to "__i386__".

They are functionally identical, but the former is a BeOS/Haiku-specfic
macro that we include in the compiler specs, and the latter is defined
by GCC.

sparc: add defines and minimum set of required files

Gets the stage0 bootstrap to run.
Imlementation is probably nonsense at this point.

build: Add riscv architecture

* I mean, qemu 3.0 supports it.
* Nobody get excited, we need all the triplets added to
our gcc buildtools. clang 7.0 seems to be cool with riscv though.

build: Add initial ARM64 target.

It will probably be just stubs for the significant future, but,
here it is anyway.

Regarding the naming: Yes, the official name is "aarch64." However,
Linux, FreeBSD, and Zircon all call it "arm64", and so we will do the same.

I've configured it initially to be a Clang-only port, making no
changes to GCC buildtools whatsoever here. We'll see if that sticks,
however.

arch: Cleanup of __ARM__ checks

* gcc 7.x defines __arm__ and __ARM__ (and others)
* clang defines __arm__ and __arm
* cleanup a few related ifdef vs if macros

Change-Id: I5da4bafac590f6fa3e10e543688001c2449f840d

ARM: Be aware of ARMEL and ARMEL

* My BeagleBone gcc defines __ARMEL__ but not
__ARM__ which breaks the native tool builds
* As ARM was originally Little Endian, we assume
__ARM__ means as such.
* Look for Big Endian ARM and define the needed big
endian preprocessors

ppc: use 64 bit physical addressing

* At least the 4xx cpu types use PAE-like 36 bit addressing, including for mapped peripherals.

Filtered flat import of Oliver's svn package management branch

Bring the changes that aren't package management related and the ones
that are but don't take effect as long as they are ignored by the build
system into the master.

Summary of changes:
* Introduce private header <directories.h> with constants for a good
deal of paths that should usually be retrieved via find_directory().
* Replace hard-coded paths by using find_directory() or the
<directories.h> constants (e.g. in drivers and the kernel).
* Add find_directory() constants needed for package management.
* Add __HAIKU_ABI_NAME and B_HAIKU_ABI_NAME macros.
* src/apps/deskbar: BeMenu.* -> DeskbarMenu.*,
DeskBarUtils.* -> DeskbarUtils.*
* Change deskbar menu settings directory from ~/config/be to
~/config/settings/deskbar.
* Other smaller cleanups, changes, and fixes.

Changed to 64 bit physical addresses for x86. This enabled PAE support.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37233 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added commented line to enable PAE.

* config/{HaikuConfig.h,types.h}:
- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
(might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
- Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
and the types __haiku_phys_[s]addr_t. The intention is to use separate
macros and types for virtual and physical addresses, since for some
architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
- Added types phys_[s]addr_t and respective printf() format macros.
- Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
B_HAIKU_PHYSICAL_{32,64}_BIT.

Might break the build under older Haiku installations. Will test next.

* Introduced new header directory "config", which ATM contains HaikuConfig.h
and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.
