Check for USE_IRAM to determine if IRAM should be used.
SoCs that don't define USE_IRAM no longer need to define
IRAMSIZE to 0 either.
When IRAM is not used, any symbols bound for IRAM will
be discarded instead of linking them in DRAM. In theory
these symbols shouldn't exist, since nothing should be
placed into IRAM sections to begin with for !USE_IRAM.
If an IRAM section attribute leaks into the plugin/codec
anyway, it should now cause a link time error.

Move the definition of DRAMSIZE into the SoC-specific
ifdef block below. This keeps the memory map defines
for a SoC together in one place and as a result it is
much easier to understand.

Move the rather large block of code that's been copied
in three separate linker scripts into the CPU header.

Move the definition of NOCACHE_BASE to the CPU headers
instead of having them copy-and-pasted in a few places.

Mostly motivated by PP needing CACHEALIGN_SIZE in linker
scripts, which can't include system.h, so move these to
cpu.h instead. Also gets rid of the default 32 byte line
size that was used if the target didn't define alignment
itself. RK24xx, DM320, and JZ4740 were missing this but
have been confirmed (from datasheets) to use 32-byte cache
lines.
Add checks to make sure the macros are appropriately
(un)defined based on the HAVE_CPU_CACHE_ALIGN define,
and make sure their values are consistent when they
are defined.
Disable HAVE_CPU_CACHE_ALIGN for hosted targets since it
arguably doesn't matter if there's a cache, if we aren't
responsible for cache maintenance.
A few files in rbcodec use CACHEALIGN_SIZE, but these
can be converted to MEM_ALIGN_SIZE, which is identical
to CACHEALIGN_SIZE if the latter is defined. On other
targets, it aligns to at least sizeof(intptr_t).

Remove now-unused stuff related to the PNX0101 processor,

Removing STUBOFFSET in commit 78542df466 caused DRAMSIZE
to be computed incorrectly, not taking into account the
16k offset used for 'IRAM'. As a result plugins & codecs
got shifted 16k upwards from their intended load address,
making them unable to load.

The mess here can be reduced by paying careful attention to
how the linker allocates LMAs/VMAs within MEMORY regions.
Changing the way .ncdata and .ncbss are defined so that they
reserve the LMA/VMA ranges they use in PLUGIN_RAM removes the
need to explicitly set the VMAs of other sections, cutting
down on the number of ifdefs needed and making the script a
bit simpler.

It looks like the GDB stub only ever worked for the Archos

Due to its similarity with S5L8702, clickwheel support and sleep can be used as-is on S5L8720. DRAM and IRAM are also configured.

Do not introduce any change for M:Robe 500 as it uses the two LCD frames
in non-obvious way.
Sansa Connect and Creative ZVM use only single front framebuffer.
Place TTB at DRAM end to minimize memory loss due to alignment.
Reserve as little as possible memory for the LCD frames.
On Sansa Connect this change extends audio buffer by 858 KiB.

The abiflags data is only used to communicate ABI information to a
program loader -- you can see what info is stored with readelf -A.
Dropping it shaves 24 bytes off of every binary (including plugins).

They were never finished, never saw any release ever, and haven't
compiled for the better part of a decade. Given their HW capabilities [1],
they are not worth trying to fix.

On Classic, IRAM1 (second 128Kb of a total of 256KB available IRAM) is
slower than DRAM. Codecs that actually are using regions of IRAM1 runs
faster when DRAM is used, so IRAM1 is disabled and only IRAM0 remains
enabled: 48KB for core and 80KB for codecs/plugins.
The next test_codec results shows how decode time is decreased:
file boosted unboosted
*.ra ~1.5% ~0.5%
*.mpc ~21% ~4.5%
*.ogg ~0.5% ~0%
nero_he*.m4a ~8% ~1%
nero*.m4a ~25% ~7%
wmapro*.wma ~4.5% ~0%
wma*.wma ~25% ~7%
In addition there is a small power save when IRAM1 HW is disabled.

(Take #2)
If .bss wasn't large enough, and .ncdata was empty, .ncbss would be
at an address overlapping the alignment-padded end of .ncdata and
and linking would fail with an overlap error.
Adds plugin load end address that accounts for IRAM going past
the final .bss sections, making IRAM overlay compatible. load_code
could also use this instead of the file size.
The .lds becomes a bit more straightforward and explicit when
assigning addresses.

If .bss wasn't large enough, and .ncdata was empty, .ncbss would be
at an address overlapping the alignment-padded end of .ncdata and
and linking would fail with an overlap error.
There also should no longer be an issue that needs special correction
with iramcopy and empty .bss. The .maps look good in that case.

It's a used by codec/plugin loading and vastly reduces code duplication. It's also a step forward in getting rid of libuisimulator in the application ports.
Apparently sh needs linker symbols prefixed with _ even if they're referenced without from C code.
