This change from evbarm was omitted in previous, but older binutils in
netbsd-10 seem to need it.

netwinder: specify kernel make variables in the makefile

There's not much sense to specify makeoptions in std.netwinder for
config(1) to move them to the generated makefile, when there's already
Makefile.netwinder.inc where these variables can be specified directly.

Move ENTRYPOINT.  Do NOT move LOADADDRESS - we don't want to use it as
it is kinda wrong and it will override the ld script.  Instead
explicitly set LINKTEXT to be empty to avoid the common kernel
makefile to supply the unwanted -Ttext option.

netwinder: fix base, minimize kern.ldscript diff with evbarm

New binutils align to 0x10000, not 0x8000 (which makes sense), so
adjust the base to be 0x10000 so that we are loaded at a page boundary
and (I guess) don't smash the firmware in the first page.  While here,
sync with ldscript.evbarm.

Makes my netwinder boot again.

netwinder: GENERIC - trim down some
It is still too big to get loaded by the firmware successfully, but
these VERBOSE options and -g symtab are the obvious hogs.

netwinder: GENERIC - trim down some more
Disable more stuff to make GENERIC just about fit.

update from HEAD

Sync with HEAD

Don't need to specify OUTPUT_FORMAT/OUTPUT_ARCH.

According to matt@, .ARM.{extab,exidx} are no longer used.

Redo previous; explicitly adjust .data load addr to get the identical ELF.

Simplify this by deciding load address at one place.

Indent with 2 spaces.

Kill trailing whitespaces.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

sync with head

Put EHABI exception tables at the end of text.
provide __exidx_start and __exidx_end symbols.

Avoid using SIZEOF to compute output section LMAs, it doesn't mix well
with orphaned sections like link_set_*.  Per discussion with Jason
Thorpe <thorpej@netbsd> on tech-toolchain.

Addresses kern/21844.

Lose -nbsd

Clean up Netwinder bootstrap:
* Put the code that runs with the MMU off in a separate section (.start).
* Use a linker script to set the VMA/LMA appropriately for each section.
* Fix kernel page table allocation and mapping of kernel text/data/bss.

...and now that kernel images > 2MB work:
* Add SYMTAB_SPACE to the GENERIC kernel so that we have DDB symbols.
* Use dbsym to load the kernel's DDB symbol area.
