8163f9a129 * Add ${PROGSYM} to CLEANFILES. 
* Instsall either the .bin or the .sym, based on whether or not
  the resulting gzboot needs to be mdsetimage'd.

04f47aa1d2 Allow MAXIMAGESIZE to be set to 0. For gzboot's that are linked 
for flash, this allows us to basically do:

	cat gzboot.bin netbsd.bin.gz > gzimg

to produce the bootable image.

7a3fa51b7f Garbage-collect the DYNAMIC_CRC_TABLE stuff. The table it computed 
was incompatible with the new CRC code, and it is largely unnecessary
now, since the static table is so much smaller.

Fixes PR kern/20935.

eb7195a019 Gzboot support for the ADI BRH eval board. This flash address allows 
the kernel to be decompressed and started at board reset if the BRH's
rotary switch is set to position 5.

d599df9587 Continue the " - . - 8" purge. Specifically: 
add	rd, pc, #foo - . - 8		->	adr	rd, foo
ldr	rd, [pc, #foo - . - 8]		->	ldr	rd, foo

Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.

Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.

a7a582e392 * Call board_init() rather than mem_init() (board_init() will take 
care of that for us).
* Call board_fini() right before jumping to the kernel entry point.

39c165f331 Add support for relocating gzboot's .text out of flash and into 
RAM (while still decompressing the image directly from flash).

This makes gzboot run a LOT faster.

the text (and, thus, the space taken up in flash) a bit.

c39065eb62 Add support for running directly out of flash: 
* Require that the builder Makefile provide a linker script.
* After making sure the MMU is disabled, check to see if
  _etext == __data_start.  If not, then copy the .data contents
  into RAM.
* Put the stack in .bss.

0fac1c42e9 gzboot -- boot a gzip'd kernel image. This is useful for booting 
compressed kernel images from flash.

This needs more work, but is a good first-pass.
