* startup/Makefile.am: Remove references to linkcmds. PR 606/bsps
* bootloader/pci.c: Fixed IO remapping so buses >= 1 are remapped.
2004-02-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de> Reduced PCI space to match bat2. Fixed incorrect region size
calculation in pci_read_bases. Set PCI latency timers to known
PR 575/bsps sane values. Changed bridge PCI settings to minimum sane instead
* startup/linkcmds: Remove. of whatever sounded neat in the PCI spec. Force pf regions to
memory mapped to preserve byte access.

PR 496/bsps
* startup/sbrk.c: New file.
* startup/bspstart.c: This patch implements 'sbrk'
for the powerpc-shared BSP to work around what's known as the
'32Mb problem' in combination with run-time loaded code.
GCC normally generates (PowerPC) code doing 'short jumps' which
requires all text segments being in the same 32Mb area of memory.
However, some run-time loaders use (e.g. heap-) memory violating the
stated limitation on hardware with more than 32Mb of memory.
(NOTE: portable loaders are probably not even aware of this
GCC/CPU specific problem.)
This patch implements a simple workaround: At boot time, the system is
only provided with 32Mb of memory. The user is supposed to load all
necessary modules prior to that limit being exhausted. Once that
happens, newlib/malloc end up trying to 'sbrk()' for more memory and
the implementation provided by this patch will then make the rest of
the physical memory available.

PR 497/bsps
* bootloader/head.S: Let the bootloader shut down the
network interface. NOTE: this involves a PPCBug system
call and will hence fail if other software is used
to boot. Need to #undef USE_PPCBUG in such cases!

Ethernet driver) would raise machine check exceptions.
