Hi,
There is a bug in the code of clearing the bss section for processor
i386.(File: cpu/i386/start.S)
In the code, bss_start addr (starting addr of bss section) is put into
the register %eax, but the code which clears the bss section refers to
the addr pointed by %edi.
This patch fixes this bug by putting bss_start into %edi register.

Fix for compile of JSE target
The attached patch fixes the compile of the JSE board in the
denx git as of 14 may 2007. It is an extremely simple patch,
it just adds the missing define of CFG_SYSTEMACE_WIDTH.
[MPC5xxx] There are networking problems on the Motion-PRO board with

temporarily disables PHY initalization sequence to make the networking
operational, until a fix is found.

[PATCH] Avoid assigning PCI resources from zero address
If a PCI IDE card happens to get a zero address assigned to it, the Linux IDE
core complains and IDE drivers fails to work. Also, assigning zero to a BAR
was illegal according to PCI 2.1 (the later revisions seem to have excluded the
sentence about "0" being considered an invalid address) -- so, use a reasonable
starting value of 0x1000 (that's what the most Linux archs are using).
Alternatively, one might have fixed the calls to pci_set_region() individually
(some code even seems to have taken care of this issue) but that would have
been a lot more work. :-)
