This patch fixes this bug by putting bss_start into %edi register.

All of the PCI/PCI-Express driver and initialization code that was in the MPC8641HPCN port has now been moved into the common drivers/fsl_pci_init.c. In a subsequent patch, this will be utilized by the 85xx ports as well. Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added. Also enable the second PCI-Express controller on 8641 by getting its BATS and CFG_ setup right. Fixed a u16 vendor compiler warning in AHCI driver too.

The code to update some bitfields was compiled only on some processors. Now, the bitfields are programmed as long as the corresponding CFG_SCCR option is defined in the board header file. This means that the board header file should not define any CFG_SCCR macros for bitfields that don't exist on that processor, otherwise the SCCR will be programmed incorrectly.

Can't check if it works on SONATA, don't have a board any more, but it at least compiles. Here is an excerpt from session log on SCHMOOGIE...

Whitespace cleanup. Define and use _START_OFFSET consistent with other processors using ppc_asm.tmpl Move additional code from .text to boot page to make room for exception vectors at start of image.

Prior to this patch the FEC driver discarded contents of a buffer descriptor without the 'LAST' bit set, so the first part of the frame was lost in case of larger frames. This fix allows to safely combine the two pieces into the whole frame.

In this scenario there is the following race condition: the fixup is (by design) set to catch the instruction following the one actually causing the exception; if an interrupt (e.g. decrementer) happens between those two instructions, the ISR code is executed before the fixup handler the machine check is no longer protected by the fixup handler as it appears as within the ISR code. In consequence the fixup approach is being phased out and replaced with explicit suppressing of MCK during a PCIe config read/write cycle.

We now allow to configure up to 16 buses; also, scanning for devices behind the PCIe-PCIe bridge is supported, so peripheral devices farther in hierarchy can be identified.
