Just started to look at reserving some RAM from u-boot and the kernel
and got a bit confused about what config options to use.
I found CONFIG_PRAM and CONFIG_SYS_MEM_TOP_HIDE and from what I can tell
one needs to set both to hide some memory from both u-boot and linux
but CONFIG_SYS_MEM_TOP_HIDE i

r14 is no longer used as non volatile GOT ptr. Instead
the volatile r12 is used so be sure to do GET_GOT in
asm code when you need to access global data.

Using the GOT in IRQ handlers requires r14 to be -ffixed-r14.
Avoid this by relocatate transfer_to_handler too.
This will allow to free up r14 later on.

Answering myself, the symlinks under tools isn't removed, not even a by a
distclean.
Kinda makes sense since now they aren't created anymore
Not sure what is going on but my build broke. I suspect commit
d984fed068b3bec8a7edaf7a3de71479abde080a

Currently, some of the tools instead set CC to be HOSTCC in order to re-use
some pattern rules -- but this fails when the user overrides CC on

To use a different link address than load address,
start.S must not make any absolute accesses. This
makes it so. Use link_off(), if defined, to calculate
the difference in load and link address.

This series removes the needs to access the GOT in

V3: squashed "crc32: Make crc32 build on non Linux too"
into this patch to form one clean patch.
I think this patch is ready for general use.

I have the same optimization queued for linux. Figured it
would be useful for u-boot too.
Testing and feedback welcome.

The #include is Linux specific. Use

Now I am done with crc32 optimizations.
Someone should look at porting over crc32_be from linux
since CRC32 BE is used by bzip and it could probably
benefit from a faster
Don't optimize for len < 4. This reduces size with
8 bytes too.
This crc32 impl is smaller that the orginal if crc32
and crc32_no_comp is impl. two separate functions(like the orginal).
That would, however, be a waste of space when both are defined.

r14 is no longer used as non volatile GOT ptr. Instead
the volatile r12 is used so be sure to do GET_GOT in
asm code when you need to access global data.

the old does four 8 bits loads.
- size is bit bigger for the new crc32:
1392(old) 1428(new) of text. Can probably be shrunk
somewhat by inlining crc32().

Only tested on PPC. little endian testing would be nice too.

NP, it was easy considering I did the first impl. for linux :)
It is probably easier to paste the missing bits into the current crc32 impl.
though.

Can't remember any figures, but is was lots by not scanning empty space. It all
depends on how full your fs is.
