ppc4xx: Add pci_pre_init() for 405 boards
This patch adds support for calling a plattform dependant
pci_pre_init() function for 405 boards. This can be used to
move the current pci_405gp_fixup_irq() function into the
board code.
This patch also makes the CFG_PCI_PRE_INIT define obsolete.
A default function with 'weak' attribute is used when
a board specific pci_pre_init() is not implemented.

Add driver for S-ATA-controller on Intel processors with South
Bridge, ICH-5, ICH-6 and ICH-7.
Implementation:
1. Code is divided in to two files. All functions, which are
controller specific are kept in "drivers/ata_piix.c" file and
functions, which are not controller specific, are kept in
"common/cmd_sata.c" file.
2. Reading and Writing from the S-ATA drive is done using PIO method.
3. Driver can be configured for 48-bit addressing by defining macro
CONFIG_LBA48, if this macro is not defined driver uses the 28-bit
addressing.
4. S-ATA read function is hooked to the File system, commands like
ext2ls and ext2load file can be used. This has been tested.
5. U-Boot command "SATA_init" is added, which initializes the S-ATA
controller and identifies the S-ATA drives connected to it.
6. U-Boot command "sata" is added, which is used to read/write, print
partition table and get info about the drives present. This I have
implemented in same way as "ide" command is implemented in U-Boot.
7. This driver is for S-ATA in native mode.
8. This driver does not support the Native command queuing and
Hot-plugging.

Fixes bug clearing the bss section for i386
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.

[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. :-)

[patch] use unsigned char in smc91111 driver for mac
the v_mac variable in the smc91111 driver is declared as a signed char ...
this causes problems when one of the bytes in the MAC is "signed" like 0xE0
because when it gets printed out, you get a display like:
0xFFFFFFE0 and that's no good
